Implement Samoan Phone Number Handling

Integrate Samoan phone numbers into your systems with these practical implementation guidelines.

Validate Number Formats for Data Integrity

Implement robust validation with these requirements:

• Strict Format Checking – Use regular expressions or dedicated libraries to enforce defined number formats
• International Prefix Handling – Support +685 international prefix for incoming and outgoing calls
• Updated Validation Rules – Monitor OOTR announcements for numbering plan changes

Example Validation Function (JavaScript):

function validateSamoanPhoneNumber(phoneNumber) {
  // Remove non-digit characters except leading +
  const cleanNumber = phoneNumber.replace(/^\+685/, '').replace(/\D/g, '');

  // Regex patterns for different number types
  const patterns = {
    landline: /^(?:[2-5]\d{4}|6[0-9]\d{4})$/,  // 5-6 digits
    mobile: /^(?:7[1-35-7]|8[3-7])\d{5}$/,      // 7 digits
    tollFree: /^800\d{3}$/,                      // 6 digits
    emergency: /^911$/                           // 3 digits
  };

  // Check against each pattern
  for (const [type, pattern] of Object.entries(patterns)) {
    if (pattern.test(cleanNumber)) {
      return {
        isValid: true,
        numberType: type,
        e164Format: type === 'emergency' ? '911' : `+685${cleanNumber}`
      };
    }
  }

  return {
    isValid: false,
    numberType: null,
    error: 'Number does not match any valid Samoan format'
  };
}

// Example usage:
console.log(validateSamoanPhoneNumber("61190"));
// { isValid: true, numberType: "landline", e164Format: "+68561190" }

console.log(validateSamoanPhoneNumber("+6857713578"));
// { isValid: true, numberType: "mobile", e164Format: "+6857713578" }

console.log(validateSamoanPhoneNumber("911"));
// { isValid: true, numberType: "emergency", e164Format: "911" }

console.log(validateSamoanPhoneNumber("1234567"));
// { isValid: false, numberType: null, error: "Number does not match..." }

Common validation pitfalls to avoid:

1. Not handling the +685 prefix – Strip it before validation, then add it back for E.164 format
2. Forgetting emergency numbers – 911 should validate even though it's only 3 digits
3. Accepting invalid mobile prefixes – Only 71, 73, 75, 76, 77, 83, 84, 85, 86, 87 are valid
4. Ignoring landline length variation – Landlines can be 5 or 6 digits
5. Missing error messages – Always return actionable error information

Adapt this validation approach to your programming language and framework.

Integrate Beyond Validation

Beyond validation, address these integration factors:

Time Zone Management

Samoa uses Pacific/Apia time zone (UTC+13 standard, UTC+14 daylight saving). Handle time zone conversions correctly for scheduling and logging:

const samoaTimeOptions = {
  timeZone: 'Pacific/Apia',
  timeZoneName: 'short'
};

const now = new Date();
console.log(now.toLocaleString('en-US', samoaTimeOptions));

Number Formatting

• Storage: Use international E.164 format (+685XXXXXXX) for consistency and interoperability
• Display: Show locally appropriate formats for better user experience (e.g., "7713 578" instead of "+6857713578")
• Input: Accept multiple formats but normalize to E.164 before storing
• Validation: Use phone number lookup services to verify carrier and number validity in real-time

Emergency Call Routing

Test emergency call routing rigorously before deployment:

1. Verify 911 routes to emergency services, not your application
2. Ensure calls work even when user authentication fails
3. Test on both WiFi and cellular connections
4. Validate GPS location data transmits correctly
5. Confirm backup routing activates during network failures

API Integration & Rate Limiting

When integrating with Samoan telecom provider APIs:

• Implement exponential backoff for failed requests
• Cache validation results to reduce API calls
• Set reasonable rate limits (typically 10-100 requests/minute for validation)
• Monitor API quotas and usage to avoid service interruptions
• Maintain fallback validation using regex when APIs are unavailable

Info: Regularly review OOTR guidelines for updates to numbering plans and validation requirements. Check regulator.gov.ws quarterly for regulatory changes.

Understand Number Portability Limitations

Samoa does not have Mobile Number Portability (MNP) as confirmed by the Samoa National Numbering Plan 2016. Users must change their number when switching providers.

Strategies for managing number changes:

1. Track multiple contact methods – Store email, secondary numbers, and social media handles
2. Prompt for updates – Ask users to verify their number periodically (every 6-12 months)
3. Detect provider switches – Monitor prefix changes (e.g., 71xx moving to 83xx suggests provider change)
4. Maintain contact history – Keep old numbers with "inactive" status for reference
5. Send verification prompts – Use SMS to verify number is still active before important communications

Database schema recommendation:

CREATE TABLE user_phone_numbers (
  id UUID PRIMARY KEY,
  user_id UUID NOT NULL,
  phone_number VARCHAR(15) NOT NULL,  -- E.164 format
  provider VARCHAR(50),                -- 'Digicel' or 'Vodafone'
  status VARCHAR(20) DEFAULT 'active', -- 'active', 'inactive', 'invalid'
  verified_at TIMESTAMP,
  created_at TIMESTAMP DEFAULT NOW(),
  deactivated_at TIMESTAMP,
  INDEX idx_user_active (user_id, status)
);

While OOTR has authority to implement MNP, no timeline has been announced as of 2024-2025.
