Landline numbers in Togo are easily identifiable by their distinct prefix, which always starts with '2':

Format: 2[2-7]XXXXXX

This means the second digit can be any number from 2 to 7, followed by six more digits. Here are a couple of examples to illustrate:

• 22234567 (Lomé region)
• 23345678 (Central region)

Recognizing this pattern is key for accurate number type identification within your applications.

📱 Mobile Numbers: Key Prefixes for Major Operators

Mobile numbers utilize specific prefixes assigned to the major operators. This allows for quick identification of the service provider associated with a given number. The formats are as follows:

Format: 7[019]XXXXXX | 9[0-36-9]XXXXXX

Here's a breakdown by operator:

• Togocel:
  • 70XXXXXX
  • 71XXXXXX
  • 90XXXXXX
• Moov Togo:
  • 79XXXXXX
  • 96XXXXXX
  • 97XXXXXX

Knowing these prefixes can be valuable for routing calls, sending SMS messages, or implementing operator-specific features in your applications.

🚨 Special Service Numbers: Short Codes for Essential Services

Emergency and utility services employ shorter, easily memorable formats:

Format: XXX or XXXX

Some common examples include:

• 117: Police
• 118: Fire Department
• 1011: Customer Service (example)

These numbers are crucial for public safety and utility access, so handling them correctly in your applications is paramount.

Developer Implementation Guide: Best Practices and Practical Tips

This section provides actionable guidance on implementing Togo's phone number system in your applications. We'll cover validation, formatting, and best practices to ensure seamless integration.

Validation Rules: Ensuring Data Integrity

Robust validation is crucial for preventing errors and ensuring data quality. You can implement these regular expressions (regex) for accurate validation of Togolese phone numbers:

// Complete validation regex (pre-number portability)
const togoPhoneRegex = /^(2[2-7]\d{6}|7[019]\d{6}|9[0-36-9]\d{6})$/;

// Usage example
function validateTogoPhone(phoneNumber) {
  return togoPhoneRegex.test(phoneNumber.replace(/\s+/g, ''));
}

// Future-proof validation regex (post-number portability, accounts for potential changes)
const togoPhoneRegexFuture = /^(228)?[2-9]\d{7}$/;

// Future-proof validation with metadata
const validateTogoNumber = (number) => {
  const cleanNumber = number.replace(/\D/g, '');
  const isValidFormat = /^(228)?[2-9]\d{7}$/.test(cleanNumber);
  const metadata = {
    isPortable: cleanNumber.startsWith('7') || cleanNumber.startsWith('9'),
    originalOperator: determineOperator(cleanNumber) // Implement your operator lookup
  };
  return { isValid: isValidFormat, ...metadata };
};

Remember to consider the implications of number portability, as discussed later in this guide. The togoPhoneRegexFuture example provides a more adaptable approach. You should choose the regex that best suits your application's needs.

E.164 Formatting: The Gold Standard

Always store and transmit phone numbers in the international E.164 format. This ensures consistency and compatibility across different systems and regions. Here's how you can format a number to E.164:

function formatToE164(phoneNumber) {
  // Remove all non-digit characters
  const cleaned = phoneNumber.replace(/\D/g, '');

  // Add country code if not present
  return cleaned.startsWith('228')
    ? '+' + cleaned
    : '+228' + cleaned;
}

This function cleans the input and adds the + prefix and country code if needed, ensuring adherence to the E.164 standard.

Best Practices and Common Pitfalls: Avoiding Development Headaches

Here are some best practices to keep in mind when working with Togolese phone numbers:

1. Number Storage: Always store numbers in E.164 format with the '+' prefix. Use VARCHAR(15) for database columns to accommodate the full length. This ensures consistency and simplifies querying.

2. Input Validation: Strip all whitespace and special characters before validation. Verify the prefix matches operator ranges and validate the length (8 digits + country code). This prevents invalid data from entering your system.

3. Display Formatting: Use spaces for readability (+228 XX XX XX XX). Consider local vs. international display contexts. Implement click-to-call formatting for mobile devices to enhance user experience.

By following these best practices, you can avoid common pitfalls and ensure your application handles Togolese phone numbers correctly.

Regulatory Compliance: Staying on the Right Side of the Law

The Autorité de Régulation des Communications Électroniques et des Postes (ARCEP) governs Togo's telecommunications sector. Key regulatory requirements include:

• Regular audit of number allocation
• Compliance with national emergency number standards
• Adherence to international formatting standards (E.164)
• Proper handling of customer data (GDPR compliance if applicable)

Staying informed about ARCEP's regulations is crucial for maintaining compliance and avoiding potential legal issues. You can find more information on their official website (https://arcep.tg/). Additionally, be aware of international standards like those defined by the ITU-T (https://www.itu.int/rec/T-REC-E.164).

Troubleshooting Common Issues: Practical Solutions for Developers

This section addresses common challenges developers face when working with Togolese phone numbers and provides practical solutions.

1. Invalid Number Format: Double-check for the correct prefix, verify the digit count, and ensure proper country code usage. Refer to the validation rules section for regex patterns.

2. Operator Identification: Validate against current prefix lists. Check ARCEP's website for updated operator assignments. Be aware that number portability can affect operator identification. Togo launched mobile number portability in May 2024, allowing users to switch operators while keeping their numbers (source: https://www.africanwirelesscomms.com/news-details?itemid=7671).

3. International Dialing: Confirm the international prefix (00) is used correctly. Verify the country code (+228) is included. Check for proper number formatting according to E.164.

By understanding these common issues and their solutions, you can effectively troubleshoot problems and ensure your application functions smoothly.
