  • 5G: Peak download speeds up to 6 Gbps (mmWave), theoretical speeds up to 20 Gbps, latency 5–10 ms (real-world), as low as 1 ms (theoretical) (Source: Faroese Telecom)
• Network Redundancy: Multiple routing paths guarantee service reliability and minimize disruptions.
• Key Operators: Faroese Telecom (Føroya Tele) is the primary operator, providing nationwide coverage and infrastructure backbone for other providers like Hey (formerly Nema) and Vodafone. (Source)

Faroe Islands Phone Number Format and Validation

Understanding the +298 Number Structure

Faroe Islands phone numbers are 6 digits long, preceded by the country code +298 for international calls. The first digit indicates the service type (landline, mobile, or special service).

Number Allocation Ranges (Source: ITU/Wikipedia):

+298 [2-9] [XXXXX]

Examples of formatted numbers:

• Landline: +298 30 20 10 (Tórshavn municipality city hall)
• Mobile: +298 21 23 45, +298 55 67 89
• Freephone: +298 80 12 34
• Premium Rate: +298 90 45 67

How to Validate Faroe Islands Phone Numbers (JavaScript Examples)

function validateFaroeseNumber(phoneNumber) {
  // Normalize by removing non-digit characters and the country code
  const normalizedNumber = phoneNumber.replace(/\D/g,'').replace(/^298/, '');

  // Check for 6-digit length and valid prefix
  return normalizedNumber.length === 6 && /^[2-9]/.test(normalizedNumber);
}

console.log(validateFaroeseNumber('+298234567')); // true
console.log(validateFaroeseNumber('298512345')); // true
console.log(validateFaroeseNumber('123456')); // false
console.log(validateFaroeseNumber('+4512345678')); // false (Danish number)

// Edge case handling
console.log(validateFaroeseNumber(null)); // throws error – handle with try/catch
console.log(validateFaroeseNumber('')); // false
console.log(validateFaroeseNumber(undefined)); // throws error – handle with try/catch

Robust validation with edge case handling:

function validateFaroeseNumberSafe(phoneNumber) {
  // Handle null, undefined, non-string inputs
  if (!phoneNumber || typeof phoneNumber !== 'string') {
    return false;
  }

  // Normalize by removing non-digit characters and the country code
  const normalizedNumber = phoneNumber.replace(/\D/g,'').replace(/^298/, '');

  // Check for 6-digit length and valid prefix (2-9)
  return normalizedNumber.length === 6 && /^[2-9]/.test(normalizedNumber);
}

// Edge cases
console.log(validateFaroeseNumberSafe(null)); // false
console.log(validateFaroeseNumberSafe(undefined)); // false
console.log(validateFaroeseNumberSafe('')); // false
console.log(validateFaroeseNumberSafe('abc')); // false
console.log(validateFaroeseNumberSafe('+298 30-20-10')); // true (handles special chars)

Advanced Phone Number Validation: Distinguishing Landline, Mobile & Emergency Numbers

Refine validation to distinguish between landlines, mobile, and emergency numbers:

const FAROE_PATTERNS = {
  landline: /^[2-4]\d{5}$/,
  mobile: /^[5-9]\d{5}$/,
  emergency: /^(112|113|1870)$/
};

function validateFaroeseNumberByType(number, type) {
    const normalizedNumber = number.replace(/\D/g,'').replace(/^298/, '');

    if (!FAROE_PATTERNS[type]) {
        return { valid: false, error: 'Invalid type. Use: landline, mobile, or emergency' };
    }

    const isValid = FAROE_PATTERNS[type].test(normalizedNumber);
    return { valid: isValid, type: isValid ? type : null };
}

console.log(validateFaroeseNumberByType('212345', 'landline')); // { valid: true, type: 'landline' }
console.log(validateFaroeseNumberByType('+298712345', 'mobile')); // { valid: true, type: 'mobile' }
console.log(validateFaroeseNumberByType('112', 'emergency')); // { valid: true, type: 'emergency' }
console.log(validateFaroeseNumberByType('212345', 'invalid_type')); // { valid: false, error: '...' }

How to Integrate Faroe Islands Emergency Services (112, 113)

Integrate with Faroe Islands emergency services by implementing these technical and regulatory requirements:

• Priority Routing: Identify emergency numbers (112, 113, 1870) and prioritize their routing.

function handleEmergencyCall(phoneNumber) {
  const emergencyNumbers = {
    '112': 'general',
    '113': 'police',
    '1870': 'medical-nonemergency'
  };
  return emergencyNumbers[phoneNumber]
    ? { priority: 'high', service: emergencyNumbers[phoneNumber] }
    : { priority: 'normal', service: 'standard' };
}

• Critical Requirements:
  • Accessibility: Emergency numbers must be reachable even on locked devices.
  • Location Services: Provide accurate caller location information to emergency services. EU regulations require caller location information with defined accuracy and reliability criteria. (Source: EU E112 Regulation)
  • Network Precedence: Emergency calls must receive priority on the network, bypassing normal traffic management.
  • Fallback Mechanisms: Ensure emergency calls can be made on any available network, including roaming networks.
  • Multi-technology Support: Support location services via GPS, Galileo (required for EU smartphones), Wi-Fi positioning, and Advanced Mobile Location (AML).

Legal and Compliance Standards:

• EU Electronic Communications Code: The Faroe Islands follows EU-aligned standards for emergency communications, ensuring 112 access with caller location information.
• Data Protection: Emergency call data must comply with the Faroe Islands Data Protection Act (Act No. 80 of 2020), which mirrors GDPR principles. (Source)
• Location Accuracy: Define accuracy and reliability criteria for caller location information to enable effective emergency response.
• Accessibility for Disabilities: Emergency communications must provide equivalent access for users with disabilities through alternative methods (SMS, real-time text, video).

Location Services Implementation:

• Use device GPS/GNSS capabilities to determine precise coordinates.
• Implement cell tower triangulation as fallback.
• Support Wi-Fi positioning when available.
• Transmit location data immediately upon emergency call initiation.
• Format location data according to local PSAP requirements.
• Test location accuracy regularly (target: <50 m in urban areas, <300 m in rural areas per EU guidelines).

Best Practices for Handling Faroe Islands Phone Numbers

Phone Number Storage and E.164 Format

• E.164 Format: Store phone numbers in international format (+298XXXXXXXX) for consistency and interoperability.
• Robust Validation: Validate thoroughly to prevent invalid numbers from entering your system. Use regular expressions and check against known prefixes.
• International Formatting: Display numbers in both international and local formats.
• Database Storage: Use VARCHAR(15) for E.164 formatted numbers. Index this column for fast lookups. Consider separate columns for country code and national number if needed for reporting.
• Normalization: Normalize input (remove spaces, hyphens, parentheses) before validation and storage.

Example normalization and storage:

function normalizeAndStore(phoneNumber) {
  // Normalize to E.164 format
  const cleaned = phoneNumber.replace(/\D/g, '');
  const withCountryCode = cleaned.startsWith('298') ? `+${cleaned}` : `+298${cleaned}`;

  // Validate before storage
  if (!validateFaroeseNumberSafe(withCountryCode)) {
    throw new Error('Invalid Faroe Islands phone number');
  }

  return {
    e164: withCountryCode,
    countryCode: '298',
    nationalNumber: withCountryCode.slice(4),
    displayFormat: withCountryCode.replace(/^(\+298)(\d{2})(\d{2})(\d{2})$/, '$1 $2 $3 $4')
  };
}

Service Integration

• Secure Protocols: Use TLS 1.3 or later for all API communication.
• Rate Limiting: Implement rate limiting to prevent abuse and ensure service availability. Recommended: 10 requests per second per client for validation APIs, 100 requests per minute for bulk operations.
• Network Monitoring: Continuously monitor network stability and performance to proactively address potential issues.
• Authentication: Use API keys or OAuth 2.0 for service authentication. Rotate keys every 90 days.
• Authorization: Implement role-based access control (RBAC) for different API operations.
• Audit Logging: Log all number validation and calling operations with timestamps, client IDs, and outcomes for security and compliance audits.

Rate limiting example:

const rateLimit = require('express-rate-limit');

const validationLimiter = rateLimit({
  windowMs: 1000, // 1 second
  max: 10, // 10 requests per second
  message: 'Too many validation requests, please try again later'
});

app.post('/api/validate-number', validationLimiter, (req, res) => {
  // Validation logic
});

Error Management

• Graceful Fallbacks: Implement error handling and fallback mechanisms to maintain functionality during network issues or service disruptions.
• Logging: Log validation failures and errors for debugging and analysis.
• Service Availability Monitoring: Monitor service availability and implement alerts for downtime.

Common Error Codes and Handling:

Error handling pattern:

async function validateWithRetry(phoneNumber, maxRetries = 3) {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      const result = await validateFaroeseNumberSafe(phoneNumber);
      return { success: true_ valid: result };
    } catch (error) {
      if (error.code === 'SERVICE_UNAVAILABLE' && attempt < maxRetries) {
        // Exponential backoff: 1s_ 2s_ 4s
        await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, attempt - 1)));
        continue;
      }
      // Log error and return failure
      console.error(`Validation failed after ${attempt} attempts:`, error);
      return { success: false, error: error.message, code: error.code };
    }
  }
}

Time Zone Handling

Use the correct time zone identifier (Atlantic/Faroe) when dealing with time-sensitive operations.

const FAROE_TZ = 'Atlantic/Faroe';
const options = { timeZone: FAROE_TZ };
const faroeTime = new Date().toLocaleString('en-US', options);

Network Operator Detection

Identify the network operator based on the prefix:

function detectOperator(prefix) {
  const operators = {
    '2': 'Faroese Telecom',
    '3': 'Faroese Telecom',
    '4': 'Faroese Telecom',
    '5': 'Faroese Telecom',
    '7': 'Hey',
    '8': 'Hey',
    '6': 'Vodafone',
    '9': 'Vodafone'
  };
  return operators[prefix] || 'Unknown';
}

Note: Prefix 4 is allocated to Faroese Telecom for fixed network services. Use operator detection cautiously – number portability allows users to switch operators while retaining their number.

Regulatory Compliance

Data Protection

The Faroe Islands Data Protection Act (Act No. 80 of 7 June 2020) governs personal data processing, including phone numbers. The Faroe Islands is not part of the EU but meets GDPR adequacy standards for data transfers (deemed adequate since 2010). (Source)

Key Requirements:

• Consent: Obtain explicit consent before processing phone numbers for marketing or non-essential purposes.
• Data Minimization: Only collect and store phone numbers necessary for your service.
• Security: Implement appropriate technical and organizational measures to protect phone number data (encryption at rest and in transit, access controls, audit logs).
• Retention: Define and enforce data retention periods; delete phone numbers when no longer needed.
• Right to Access: Users can request access to their stored phone number data.
• Right to Erasure: Users can request deletion of their phone number data ("right to be forgotten").
• Data Breach Notification: Report data breaches involving phone numbers to the Faroe Islands Data Protection Authority within 72 hours.

Number Portability

Number portability allows users to retain their phone numbers when switching between operators. As a developer:

• Don't rely solely on prefix-based operator detection.
• Query carrier lookup APIs for current operator information.
• Handle number portability in billing and routing systems.

Note: The Faroe Islands telecommunications framework supports number portability as part of competitive market regulations.

Emergency Service Access

• Mandatory Access: Provide unrestricted access to emergency numbers (112, 113) in all telecommunications applications.
• Priority Handling: Emergency calls must bypass call queues, rate limits, and credit checks.
• No Blocking: Never block or restrict emergency calls under any circumstances, including non-payment scenarios.
• Testing: Test emergency call routing regularly using test facilities – never dial actual emergency services.

Compliance Checklist

• Store phone numbers in E.164 format with encryption
• Implement user consent mechanisms for phone number collection
• Provide emergency number access without restrictions
• Implement caller location services for emergency calls
• Log all number processing operations for audit trails
• Define and enforce data retention policies
• Implement secure API authentication (TLS 1.3+, API keys/OAuth)
• Test emergency call routing (use test facilities)
• Document data processing activities (DPA Article 44 requirement)
• Establish data breach notification procedures
• Provide user access to their stored data
• Honor right to erasure requests within 30 days

Troubleshooting Common Issues

Q: Validation fails for numbers with spaces or hyphens.

Normalize input by removing non-digit characters before validation.

Q: Emergency calls not connecting.

Verify emergency numbers are not subject to rate limiting, authentication, or credit checks. Test routing with official test facilities.

Q: Caller location not accurate.

Ensure GPS/GNSS permissions are granted, implement Wi-Fi positioning fallback, and test in various environments (urban, rural, indoor).

Q: International calls to Faroe Islands fail.

Confirm country code +298 is used (not Denmark's +45). The Faroe Islands has had a separate country code since 1998.

Q: Operator detection returns wrong carrier.

Number portability allows users to switch operators while keeping their number. Use real-time carrier lookup APIs instead of prefix-based detection.

Testing Recommendations

• Unit Testing: Test validation functions with valid/invalid numbers, edge cases (null, empty, special characters), and all prefix ranges.
• Integration Testing: Test with actual Faroese phone numbers (use test numbers provided by operators).
• Emergency Call Testing: Use designated test facilities, never dial actual emergency services for testing.
• Load Testing: Validate rate limiting and performance under high request volumes (target: <100 ms response time for validation).
• Location Testing: Test location services in different environments and with different positioning technologies.
• Internationalization Testing: Test with different locale settings and number formatting conventions.
