Papua New Guinea Phone Numbers: Format, Area Code & Validation Guide

Introduction

Papua New Guinea phone numbers use the country code +675 and follow specific formats for mobile and landline numbers. This comprehensive guide covers PNG phone number validation, NICTA regulations, carrier prefixes for Digicel, bmobile, and Vodafone PNG, plus JavaScript code examples for implementing validation in your applications.

Whether you're building contact forms, CRM systems, SMS platforms, or telecommunications applications, you'll learn how to properly validate, format, and store Papua New Guinea phone numbers using the E.164 international phone number format.

Prerequisites: Basic understanding of regular expressions, phone number validation concepts, and JavaScript/Node.js. Examples use JavaScript, but patterns apply to any language.

PNG Telecommunications Regulatory Authority (NICTA)

The National Information and Communications Technology Authority (NICTA) governs PNG's telecommunications sector, including number allocation and licensing. NICTA operates under the NICTA Act (2009) and publishes regulatory updates through official gazettes – including the National Gazette No. G949 (September 26, 2025) updating Standard and Special Conditions of Individual Licences Rule 2025.

Stay informed about NICTA's regulations at https://www.nicta.gov.pg/. NICTA regularly publishes consultative papers and public inquiries, including the Operator Licensing (Special Temporary Authorisations) Rule (September 2025) and Draft Spectrum Outlook & Roadmap 2025 to 2030 (June 2025). Subscribe to NICTA updates to maintain compliance as numbering plans and licensing requirements evolve.

Compliance Requirements:

• SIM Card Registration: Mandatory since July 23, 2016 under SIM Card Registration Regulation 2016 (Statutory Instrument No.7 of 2016). Register all SIMs with valid identification documents. Failure to register results in SIM deactivation without notice.
• Type Approval: Obtain NICTA type approval for telecommunications equipment before deployment.
• Penalties: Non-compliance with SIM registration results in service deactivation. Mobile network operators face fines for failing to enforce registration requirements. Validate registered numbers to ensure service continuity.

Number Format Specifications

PNG phone numbers consist of 7–8 digits (landlines) or 8 digits (mobile). All numbers use country code +675.

Geographic (Landline) Numbers

Landline numbers follow a regional structure. Identify the general location based on prefix. Regional prefixes (verified from NICTA numbering allocations):

• Port Moresby & Central: +675 3XX XXXX (7–8 digits) – National Capital District
• Other Urban Centers: +675 4XX XXXX (7–8 digits) – Lae/Morobe region
• Regional Areas: +675 5XX XXXX (7–8 digits) – Highlands region

The "+675" is the international country code for PNG. Within PNG, numbers appear without the country code.

Format Selection for Applications:

• Storage: Always use E.164 format (+675XXXXXXXX) for database storage to ensure consistency and enable international portability
• Display: Show local format (without country code) for PNG-based users; show international format (+675) for international contexts
• Input Acceptance: Accept both formats from users, normalize to E.164 before validation and storage
• API Integration: Use E.164 format for all API calls to SMS gateways and telephony services

Key Examples:

• Port Moresby: 3201234 (local) or +6753201234 (international E.164)
• Urban Center: 4201234 (local) or +6754201234 (international E.164)
• Regional Area: 5301234 (local) or +6755301234 (international E.164)

Mobile Numbers

Mobile numbers in PNG are 8 digits and begin with 7 or 8. The market includes three mobile network operators (MNOs) as of 2025:

• Digicel PNG (Telstra-owned since July 2022): +675 7XXX XXXX – Series 70XX to 74XX, 79XX
• bmobile (Bemobile Limited): +675 75XX XXXX, +675 76XX XXXX – Trading as bmobile
• Vodafone PNG (Digitec Communications, launched April 2022): +675 81XX XXXX, +675 82XX XXXX

Market Context (verified January 2025 from Mordor Intelligence):

• Digicel PNG controls approximately 91% market share with 945 cell sites covering 85% of population
• Vodafone PNG launched services in April 2022, becoming PNG's third MNO alongside Digicel and bmobile
• Telstra acquired Digicel Pacific (including PNG operations) in July 2022 with Australian government backing
• bmobile partnered with Vodafone for network infrastructure improvements starting in 2014
• All three MNOs operate GSM, 3G, and 4G LTE networks (no 5G deployment as of 2025)
• Network coverage expanded from less than 3% in 2006 to more than 92% by early 2022
• Coral Sea submarine cable (2024) provides 40 Tbps backhaul capacity, reducing latency

Examples:

• Digicel: 71234567 (local) or +67571234567 (international E.164)
• bmobile: 75123456 (local) or +67575123456 (international E.164)
• Vodafone PNG: 81234567 (local) or +67581234567 (international E.164)

Special Service Numbers

These numbers serve specific functions, such as toll-free services. Recognize these numbers to prevent accidental dialing or incorrect routing.

• Toll-Free: 1800 XXXX (4-digit suffix) – 8 digits total
• Operator Services: 0XX(X) – Various operator and emergency services

Example: 18001234 (accessible only within PNG, not dialable internationally)

Implementation Guide: Building Robust Validation

Implement validation in your application using these techniques.

1. Validation Patterns: Using Regular Expressions

Regular expressions (regex) provide powerful phone number validation. Adapt these patterns:

// Landline validation (7-8 digits)
const landlinePattern = {
    portMoresby: /^3[0-2]\d{5,6}$/,    // Port Moresby/Central: 300-329
    urbanCenters: /^4[2-5]\d{5,6}$/,   // Lae/Morobe: 42X-45X
    regional: /^5[3-4]\d{5,6}$/        // Highlands: 530-549
};

// Mobile validation (8 digits)
const mobilePattern = {
    digicel: /^7[0-4,9]\d{6}$/,        // Digicel: 70-74, 79
    bmobile: /^7[5-6]\d{6}$/,          // bmobile: 75-76
    vodafonePNG: /^8[1-2]\d{6}$/       // Vodafone PNG: 81-82
};

// Special service validation
const tollFreePattern = /^1800\d{4}$/;

// Comprehensive mobile pattern (all operators)
const allMobilePattern = /^[78]\d{7}$/;

// Example usage:
const isDigicel = mobilePattern.digicel.test('71234567'); // Returns true
const isMobile = allMobilePattern.test('75123456'); // Returns true

Edge Cases to Handle:

• Leading zeros: Some users enter 071234567 instead of 71234567 – strip leading zero for mobile numbers
• Country code variations: Accept +675, 675, or no prefix
• Spacing: Handle formats like 7123 4567, 71 234 567, or 71-234-567
• Parentheses: Some users write (675) 71234567 or +675 (71) 234567
• International prefix: Handle 00675 (international access code + country code)
• Length validation: Ensure exactly 7-8 digits for landlines, exactly 8 for mobile after sanitization

2. Input Sanitization: Cleaning Up User Input

Users enter phone numbers with spaces, hyphens, or parentheses. Sanitize the input before validation:

function sanitizePNGNumber(number) {
  // Remove all non-digit characters except leading +
  let cleaned = number.replace(/[^\d+]/g, '');

  // Handle international formats
  if (cleaned.startsWith('+675')) {
    cleaned = cleaned.substring(4); // Remove +675
  } else if (cleaned.startsWith('00675')) {
    cleaned = cleaned.substring(5); // Remove 00675 (international access)
  } else if (cleaned.startsWith('675')) {
    cleaned = cleaned.substring(3); // Remove 675
  }

  // Remove leading zero for mobile numbers
  if (cleaned.startsWith('0') && cleaned.length === 9) {
    cleaned = cleaned.substring(1);
  }

  return cleaned;
}

// Example usage:
console.log(sanitizePNGNumber('+675 7123 4567')); // Returns: '71234567'
console.log(sanitizePNGNumber('(675) 71-234-567')); // Returns: '71234567'
console.log(sanitizePNGNumber('071234567')); // Returns: '71234567'

This function removes all non-digit characters, handles international prefixes (+675, 00675, 675), and strips leading zeros from mobile numbers.

3. Comprehensive Validation: Putting It All Together

Combine sanitization and regex validation into a single function with detailed error handling:

function validatePNGNumber(number) {
  // Sanitize input
  const cleanedNumber = sanitizePNGNumber(number);

  // Check if empty
  if (!cleanedNumber) {
    return { valid: false, type: null, error: 'Empty number' };
  }

  // Validate mobile numbers (8 digits)
  if (cleanedNumber.length === 8) {
    if (mobilePattern.digicel.test(cleanedNumber)) {
      return { valid: true, type: 'mobile', operator: 'Digicel PNG', cleaned: cleanedNumber };
    }
    if (mobilePattern.bmobile.test(cleanedNumber)) {
      return { valid: true, type: 'mobile', operator: 'bmobile', cleaned: cleanedNumber };
    }
    if (mobilePattern.vodafonePNG.test(cleanedNumber)) {
      return { valid: true, type: 'mobile', operator: 'Vodafone PNG', cleaned: cleanedNumber };
    }
    return { valid: false, type: null, error: 'Invalid mobile number prefix' };
  }

  // Validate landline numbers (7-8 digits)
  if (cleanedNumber.length === 7 || cleanedNumber.length === 8) {
    if (landlinePattern.portMoresby.test(cleanedNumber)) {
      return { valid: true, type: 'landline', region: 'Port Moresby/Central', cleaned: cleanedNumber };
    }
    if (landlinePattern.urbanCenters.test(cleanedNumber)) {
      return { valid: true, type: 'landline', region: 'Lae/Urban Centers', cleaned: cleanedNumber };
    }
    if (landlinePattern.regional.test(cleanedNumber)) {
      return { valid: true, type: 'landline', region: 'Highlands', cleaned: cleanedNumber };
    }
  }

  // Validate toll-free numbers
  if (tollFreePattern.test(cleanedNumber)) {
    return { valid: true, type: 'toll-free', cleaned: cleanedNumber };
  }

  // Invalid number
  return {
    valid: false,
    type: null,
    error: `Invalid PNG number format. Expected 7-8 digits for landline or 8 digits for mobile, got ${cleanedNumber.length} digits`
  };
}

// Example usage:
const result1 = validatePNGNumber('+675 7123 4567');
console.log(result1);
// { valid: true, type: 'mobile', operator: 'Digicel PNG', cleaned: '71234567' }

const result2 = validatePNGNumber('3201234');
console.log(result2);
// { valid: true, type: 'landline', region: 'Port Moresby/Central', cleaned: '3201234' }

const result3 = validatePNGNumber('12345');
console.log(result3);
// { valid: false, type: null, error: 'Invalid PNG number format...' }

The function returns an object with validation status, number type, operator/region information, and cleaned number for further processing.

4. Error Handling and User Feedback

Provide clear, specific error messages based on validation failure type:

function displayValidationError(validationResult, inputValue) {
  if (validationResult.valid) {
    return null; // No error
  }

  const cleaned = sanitizePNGNumber(inputValue);

  // Specific error messages based on failure reason
  if (!cleaned) {
    return 'Enter a phone number.';
  }

  if (cleaned.length < 7) {
    return 'PNG phone numbers must be at least 7 digits. Check your number.';
  }

  if (cleaned.length > 8) {
    return 'PNG phone numbers cannot exceed 8 digits. Remove extra digits.';
  }

  if (cleaned.length === 8 && cleaned[0] !== '7' && cleaned[0] !== '8') {
    return 'PNG mobile numbers must start with 7 or 8. Check your number.';
  }

  if (validationResult.error === 'Invalid mobile number prefix') {
    return 'This mobile number prefix is not assigned to PNG operators. Valid prefixes: 70-74, 75-76, 79, 81-82.';
  }

  // Generic error
  return 'Invalid PNG phone number format. Enter a valid PNG landline (7-8 digits) or mobile number (8 digits starting with 7 or 8).';
}

// Example usage:
const result = validatePNGNumber(userInput);
if (!result.valid) {
  const errorMsg = displayValidationError(result, userInput);
  displayErrorMessage(errorMsg);
}

5. Number Formatting: Displaying Numbers Consistently

Format numbers consistently to improve readability and ensure data integrity. The E.164 format (+675XXXXXXX) is the international standard and is recommended for storing phone numbers:

function formatToE164(number) {
  const cleaned = sanitizePNGNumber(number);

  // Validate before formatting
  const validation = validatePNGNumber(number);
  if (!validation.valid) {
    throw new Error(`Cannot format invalid number: ${validation.error}`);
  }

  return `+675${cleaned}`;
}

// Format for display with spacing
function formatForDisplay(number, international = false) {
  const cleaned = sanitizePNGNumber(number);
  const validation = validatePNGNumber(number);

  if (!validation.valid) {
    return number; // Return original if invalid
  }

  if (international) {
    // International format with spacing
    if (cleaned.length === 8) {
      return `+675 ${cleaned.substring(0, 4)} ${cleaned.substring(4)}`;
    } else {
      return `+675 ${cleaned}`;
    }
  } else {
    // Local format with spacing
    if (cleaned.length === 8) {
      return `${cleaned.substring(0, 4)} ${cleaned.substring(4)}`;
    } else {
      return cleaned;
    }
  }
}

// Example usage:
console.log(formatToE164('71234567')); // +67571234567
console.log(formatForDisplay('71234567', true)); // +675 7123 4567
console.log(formatForDisplay('71234567', false)); // 7123 4567

6. Mobile Number Portability (MNP): Handling Carrier Changes

Users can switch carriers while keeping their mobile number through Mobile Number Portability (MNP). NICTA initiated Phase 2 of MNP Public Consultation in April 2024, indicating ongoing development of MNP business rules and implementation.

MNP Status (verified January 2025):

• Implementation Phase: NICTA completed Phase 1 inquiry (2016-2019) and is developing Phase 2 business rules
• Current Status: MNP not yet operational in PNG market; planned for future implementation
• Carrier Identification: Prefixes (7XX vs. 8XX) currently reliably indicate carrier, but will become unreliable once MNP launches
• Developer Impact: Applications requiring current carrier identification will need to integrate with MNP database once service launches

MNP Integration Guidance (for Future Implementation):

• Monitor NICTA consultations page for MNP launch announcements
• Once operational, integrate with official MNP database via API (specifications to be published by NICTA)
• Expect real-time or batch lookup services to determine current carrier from ported numbers
• Plan for additional latency (50-200 ms) and costs for per-lookup MNP queries
• Cache MNP lookup results with short TTL (24-48 hours) to balance cost and accuracy
• Implement fallback logic if MNP service is unavailable

7. Network Interoperability: Testing Across Networks

Test your validation and formatting logic across different network types and operators to ensure consistent performance:

Testing Methodology:

1. Unit Testing: Test validation functions with known valid/invalid numbers for each operator
2. Integration Testing: Send test SMS or make test calls to real numbers across all three operators
3. Cross-Network Testing: Verify Digicel-to-bmobile, Digicel-to-Vodafone, and bmobile-to-Vodafone connectivity
4. Format Handling: Test international format (+675), local format, and various spacing patterns
5. Edge Case Testing: Test boundary conditions (minimum/maximum lengths, invalid prefixes, special characters)

Test Framework Example (Jest/Mocha):

describe('PNG Phone Number Validation', () => {
  test('validates Digicel mobile numbers', () => {
    expect(validatePNGNumber('71234567').valid).toBe(true);
    expect(validatePNGNumber('79999999').valid).toBe(true);
  });

  test('validates bmobile numbers', () => {
    expect(validatePNGNumber('75123456').valid).toBe(true);
    expect(validatePNGNumber('76123456').valid).toBe(true);
  });

  test('validates Vodafone PNG numbers', () => {
    expect(validatePNGNumber('81234567').valid).toBe(true);
    expect(validatePNGNumber('82123456').valid).toBe(true);
  });

  test('validates Port Moresby landlines', () => {
    expect(validatePNGNumber('3201234').valid).toBe(true);
  });

  test('rejects invalid prefixes', () => {
    expect(validatePNGNumber('91234567').valid).toBe(false);
    expect(validatePNGNumber('60123456').valid).toBe(false);
  });

  test('handles international format', () => {
    const result = validatePNGNumber('+675 7123 4567');
    expect(result.valid).toBe(true);
    expect(result.cleaned).toBe('71234567');
  });
});

8. Regional Variations and Future-Proofing

Account for potential regional variations in number formats within PNG and anticipate future changes:

Known Regional Patterns (from Wikipedia):

• Port Moresby/Central: 300-329 prefix range
• Southern Region: Oro (642), Milne Bay (641-643), Western (645-646), Gulf (648)
• Momase Region: Madang (422-424), East Sepik (450, 456), Sandaun (457-459)
• Highlands: Eastern Highlands (530-532), Chimbu (535), Southern Highlands (540, 549), Western Highlands (541-542, 545-546), Enga (547)
• Islands: Manus (970), North Solomons (973, 975-976), East New Britain (980-982, 985, 987, 989), New Ireland (983), West New Britain (984)

Design Patterns for Flexibility:

// Configuration-driven validation (externalize patterns)
const PNG_VALIDATION_CONFIG = {
  version: '1.0.0',
  lastUpdated: '2025-01-15',
  patterns: {
    mobile: {
      digicel: { regex: /^7[0-4,9]\d{6}$/, description: 'Digicel PNG' },
      bmobile: { regex: /^7[5-6]\d{6}$/, description: 'bmobile' },
      vodafone: { regex: /^8[1-2]\d{6}$/, description: 'Vodafone PNG' }
    },
    landline: {
      portMoresby: { regex: /^3[0-2]\d{5,6}$/, description: 'Port Moresby/Central' },
      urban: { regex: /^4[2-5]\d{5,6}$/, description: 'Urban Centers' },
      highlands: { regex: /^5[3-4]\d{5,6}$/, description: 'Highlands' }
    }
  }
};

// Load patterns from external config (JSON/API) for easy updates
async function loadValidationRules() {
  try {
    const response = await fetch('https://api.yourservice.com/png-validation-rules');
    return await response.json();
  } catch (error) {
    // Fallback to embedded rules
    return PNG_VALIDATION_CONFIG;
  }
}

Future-Proofing Checklist:

• Externalize regex patterns to configuration files or remote API
• Version your validation rules to track changes over time
• Subscribe to NICTA updates and review quarterly for numbering plan changes
• Build admin interface to update validation rules without code deployment
• Log validation failures to identify emerging patterns requiring rule updates

9. Historical Context and Infrastructure Development

PNG's telecommunications infrastructure has evolved significantly. Starting with 17 telephone exchanges in 1955, the country experienced substantial growth and modernization. The National Transmission Network (NTN), operated by PNG DataCo, comprises over 7,000 km of fiber optic cable connecting PNG to the global digital landscape.

Network coverage expanded from less than 3% of population in 2006 to more than 92% by early 2022 (verified January 2025). The ongoing NTN expansion into remote areas bridges the digital divide, opening new user bases for applications targeting PNG markets. The Coral Sea submarine cable (operational 2024) provides 40 Tbps backhaul capacity, reducing latency by 100× and wholesale costs by 80%.

10. Compliance and Regulatory Updates

Stay compliant with NICTA's regulations:

• Type Approval: Obtain NICTA type approval for telecommunications equipment before deployment (validity: 3 years under new regulations)
• Error Handling: Implement proper error handling to provide clear feedback on validation failures
• SIM Card Registration: All mobile numbers must be registered with valid ID; unregistered SIMs face deactivation
• Numbering Standards: Follow official NICTA numbering allocations and formats

Recent Regulatory Updates (verified January 2025):

• National Gazette No. G949 (September 26, 2025): Standard and Special Conditions of Individual Licences Rule 2025
• Operator Licensing (Special Temporary Authorisations) Rule (September 2025)
• Consumer Protection Rule Amendment 2024 (Draft, May 2025)
• Draft Spectrum Outlook & Roadmap 2025 to 2030 (June 2025)

Developer Impact:

• Licensing Rules: Ensure your application/service complies with operator licensing requirements if providing telecommunications services
• Quality of Service: New Telecommunications QoS Rule-2022 sets performance standards for network reliability
• Type Approval: If deploying telecom equipment, obtain approval under ICT Equipment Type Approval Rule-2022
• Spectrum Usage: 5G-ready spectrum allocations (700 MHz, 3.5 GHz) signal future network upgrades – plan for higher bandwidth requirements

Monitor NICTA's consultations and public notices to stay current with evolving regulatory requirements.

Testing and Verification

Test thoroughly to ensure your implementation works as expected across all PNG number formats and operators:

Comprehensive Test Suite:

Testing Framework Example (Complete):

describe('PNG Phone Validation - Comprehensive Tests', () => {
  const validNumbers = [
    { input: '71234567', type: 'mobile', operator: 'Digicel PNG' },
    { input: '75123456', type: 'mobile', operator: 'bmobile' },
    { input: '81234567', type: 'mobile', operator: 'Vodafone PNG' },

    test(`validates ${input} as ${type}`, () => {
      const result = validatePNGNumber(input);
      expect(result.valid).toBe(true);
      expect(result.type).toBe(type);
      if (operator) expect(result.operator).toBe(operator);
    });
  });

  const invalidNumbers = [
    '91234567',  // Invalid prefix
    '712345',    // Too short
    '712345678', // Too long
    'abcdefgh',  // Non-numeric
    '',          // Empty
    '+1234567890' // Wrong country code
  ];

  invalidNumbers.forEach(input => {
    test(`rejects invalid number: ${input}`, () => {
      const result = validatePNGNumber(input);
      expect(result.valid).toBe(false);
    });
  });
});

Recommended Testing Tools:

• Unit Testing: Jest, Mocha, or Jasmine for JavaScript validation logic
• Integration Testing: Twilio/MessageBird test numbers for SMS delivery verification
• Load Testing: Artillery or JMeter to test validation performance under load
• Monitoring: Log validation failures in production to identify edge cases requiring rule updates

Frequently Asked Questions (FAQ)

What is the country code for Papua New Guinea?

The country code for Papua New Guinea is +675. All PNG phone numbers use this international dialing code. When calling from outside PNG, dial +675 followed by the local number (7–8 digits for landlines, 8 digits for mobile). From within PNG, dial only the local number without the country code.

How do I format a PNG phone number in E.164 format?

Format PNG phone numbers in E.164 format as +675XXXXXXXX (no spaces or special characters). Remove all spaces, hyphens, and parentheses, then prepend +675 to the local number. For example, the local number 71234567 becomes +67571234567 in E.164 format. E.164 is the recommended format for database storage and API integration. Learn more about E.164 phone number formatting.

What mobile operators serve Papua New Guinea?

PNG has three mobile network operators (MNOs) as of 2025:

• Digicel PNG (Telstra-owned since July 2022): Prefix 70XX-74XX, 79XX | ~91% market share | 945 cell sites
• bmobile (Bemobile Limited): Prefix 75XX-76XX | Partnership with Vodafone since 2014
• Vodafone PNG (Digitec Communications, launched April 2022): Prefix 81XX-82XX | Newest entrant

All operators provide GSM, 3G, and 4G LTE networks covering 92%+ of population. No 5G services available as of 2025.

How do I validate Papua New Guinea mobile numbers?

Validate PNG mobile numbers by checking they are exactly 8 digits and begin with 7 or 8:

• Digicel: 70-74, 79 prefixes → /^7[0-4,9]\d{6}$/
• bmobile: 75-76 prefixes → /^7[5-6]\d{6}$/
• Vodafone PNG: 81-82 prefixes → /^8[1-2]\d{6}$/

Always sanitize input first by removing non-digit characters and stripping country code prefix (+675). See code examples in sections 1-3 above.

What is Mobile Number Portability (MNP) in Papua New Guinea?

Mobile Number Portability (MNP) allows PNG users to switch carriers while keeping their phone number. Current Status: NICTA initiated Phase 2 of MNP Public Consultation in April 2024, but MNP is not yet operational in PNG (as of January 2025). Once implemented, carrier prefixes (7XX vs. 8XX) will no longer reliably indicate current carrier. Applications requiring carrier identification will need to integrate with NICTA's official MNP database via API (specifications pending).

Typical MNP Process (once operational):

• Request port from new carrier
• Porting typically takes 3-5 business days
• Number remains active during port
• Old SIM deactivates, new SIM activates upon completion

What telecommunications authority regulates PNG phone numbers?

The National Information and Communications Technology Authority (NICTA) governs PNG's telecommunications sector under the NICTA Act (2009). NICTA handles:

• Number allocation and numbering plans
• Operator licensing (mobile, fixed, VoIP)
• Type approval for telecommunications equipment
• SIM card registration enforcement
• Regulatory updates via official gazettes

Contact NICTA: +675 303 3200 | P.O. Box 8444, BOROKO, NCD, Papua New Guinea

How do I distinguish PNG landline numbers from mobile numbers?

Landline numbers: 7–8 digits starting with 3, 4, or 5

• Port Moresby/Central: 3XX XXXX (300-329)
• Urban Centers/Lae: 4XX XXXX (420-459)
• Highlands: 5XX XXXX (530-549)

Mobile numbers: Exactly 8 digits starting with 7 or 8

• 7 prefix: Digicel or bmobile
• 8 prefix: Vodafone PNG or bmobile

Use the first digit and length to quickly identify number type in your application.

• Validate both mobile (8 digits, prefixes 7X/8X) and landline (7-8 digits, prefixes 3X/4X/5X) formats
• Handle international format variations (+675, 00675, 675) and sanitize input
• Comply with NICTA SIM card registration requirements (mandatory since 2016)
