How to Validate Angola Phone Numbers: Regex Patterns and Code Examples

Implement robust Angola phone number validation to ensure data integrity and prevent formatting errors.

What Regex Patterns Validate Angola Phone Numbers?

Use these regular expressions to validate Angola phone numbers by type:

// Regular expressions for validation
const patterns = {
  landline: /^2[2-9]\d{7}$/,
  mobile: /^9[1-9]\d{7}$/,
  specialService: /^1\d{2}$/,  // 3-digit services like 112, 116
  consumerService: /^1\d{4}$/  // 5-digit services like 15555
};

// Example implementation
function validateAngolanNumber(number, type) {
  return patterns[type].test(number);
}

// Example usage
console.log(validateAngolanNumber('222123456', 'landline')); // true
console.log(validateAngolanNumber('923456789', 'mobile')); // true
console.log(validateAngolanNumber('112', 'specialService')); // true
console.log(validateAngolanNumber('15555', 'consumerService')); // true

The validateAngolanNumber function validates Angola phone numbers by type and returns true if valid, false otherwise. Test your validation logic thoroughly with various valid and invalid inputs to ensure accurate phone number verification.

How to Handle Phone Number Validation Errors

Anticipate validation errors and provide clear feedback to users:

function formatAngolanNumber(number) {
  // Remove any non-digit characters
  const cleaned = number.replace(/\D/g, '');

  // Check length and prefix
  if (cleaned.length !== 9 && cleaned.length !== 3 && cleaned.length !== 5) {
    throw new Error('Invalid number length. Angolan numbers must be 9 digits (landline/mobile), 3 digits (emergency services), or 5 digits (consumer services).');
  }

  // Format according to type
  if (cleaned.startsWith('2')) {
    return `${cleaned.slice(0, 2)} ${cleaned.slice(2, 5)} ${cleaned.slice(5)}`;
  } else if (cleaned.startsWith('9')) {
    return `${cleaned.slice(0, 2)} ${cleaned.slice(2, 5)} ${cleaned.slice(5)}`;
  } else if (cleaned.startsWith('1')) {
    return cleaned; // No formatting needed for special service numbers
  }

  throw new Error('Invalid number format. Please check the prefix.');
}

// Example usage (try-catch block for error handling)
try {
  console.log(formatAngolanNumber('+244923456789')); // Output: 92 345 6789
} catch (error) {
  console.error(error.message);
}

The try-catch block demonstrates graceful error handling for Angola phone number formatting.
