Understanding Niger's Phone Number System

ARCEP (Autorité de Régulation des Communications Électroniques et de la Poste) regulates Niger's phone number system and country code +227 allocation. This independent administrative authority, established by Law 2018-47 of July 12, 2018, ensures the numbering system adheres to a predictable structure for both mobile and fixed-line numbers.

Core Number Structure

All Nigerien phone numbers follow this pattern:

+227 XX XXX XXX
│    │  │   │
│    │  │   └── Subscriber Number (Last 3 digits)
│    │  └────── Subscriber Number (Middle 3 digits)
│    └───────── Number Type Prefix (2-9)
└────────────── Country Code

Number Types and Formats

Prefixes indicate number type:

Geographic Prefix Allocation by Region

Fixed-line numbers use prefix 20-21 with specific allocations for major cities and regions (source: ITU Niger numbering plan):

Prefix 21 is used for Wireless Local Loop (WLL) services operated by Niger Telecoms (SONITEL).

Niger Mobile Operators and Network Prefixes

As of 2025, ARCEP regulates four major telecommunications operators in Niger with specific prefix allocations for mobile numbers:

Operator Prefix Assignments

Sources:

• Market share data: ARCEP Q1 2024 report and GlobalData Niger Telecom Report 2025
• Prefix allocations: ITU Niger numbering updates 2019 and Wikipedia: Telephone numbers in Niger

Prefix Details:

• Airtel (96): Includes sub-ranges 96 05-29, 96 40-59, 96 66-67, 96 87-89, 96 96-99
• Moov (93): Includes sub-ranges 93 21-23, 93 80-83, 93 90-93
• Zamani (94): Includes sub-ranges 94 24-25, 94 28, 94 62-63, 94 84-85, 94 94-95
• Niger Telecoms (83): Number block +227 83 XX XX XX allocated for mobile services

Note: Prefix 8 serves newer mobile services and specific operators. Always verify current prefix allocations via ARCEP's official website for the most up-to-date assignments.

Toll-Free and Premium Numbers

Toll-free numbers and premium-rate services in Niger may use different prefixes. While standard consumer numbers use prefixes 2-9, specialized services include:

• Short codes (2-5 digits): Used for value-added services, customer service, and mobile operator functions
• Format: Typically 3-5 digit numbers (e.g., 100, 111, 123, 222, 333)
• Examples: 100 (credit inquiry), 111 (customer service), 222 (prepaid distribution)

For business toll-free number allocation and validation requirements, consult ARCEP's e-services platform for current regulations and number reservations.

Phone Number Validation & Formatting Implementation

Implement Niger phone number validation and formatting using these practical code examples for JavaScript applications.

1. Niger Phone Number Validation with Regex

Validate Niger phone numbers using regex patterns to ensure data integrity and correct format:

// Full international format validation (with optional + or 00)
const internationalPattern = /^(\+227|00227)[2-9]\d{7}$/;

// National format validation
const nationalPattern = /^[2-9]\d{7}$/;

// Type-specific validation
const typePatterns = {
  geographic: /^[2-7]\d{7}$/,
  mobile: /^[89]\d{7}$/,
  mobileNine: /^9\d{7}$/,  // Most common mobile prefix
  airtel: /^96\d{6}$/,      // Airtel Niger (prefix 96)
  moov: /^93\d{6}$/,        // Moov Niger (prefix 93)
  zamani: /^94\d{6}$/,      // Zamani Telecom (prefix 94)
  nigerTelMobile: /^83\d{6}$/  // Niger Telecoms mobile (prefix 83)
};

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

  // Handle international format
  let localNumber = cleanedNumber;
  if (cleanedNumber.startsWith('227')) {
    localNumber = cleanedNumber.slice(3);
  } else if (cleanedNumber.startsWith('00227')) {
    localNumber = cleanedNumber.slice(5);
  }

  if (type === 'any') {
    return nationalPattern.test(localNumber);
  }

  return typePatterns[type] ? typePatterns[type].test(localNumber) : false;
}

// Example usage:
console.log(validateNigerNumber('+22796234567', 'mobile')); // true (Airtel)
console.log(validateNigerNumber('+22793456789', 'moov')); // true (Moov)
console.log(validateNigerNumber('20123456', 'geographic')); // true (Niamey fixed-line)
console.log(validateNigerNumber('0022794234567', 'zamani')); // true (Zamani)
console.log(validateNigerNumber('+22711234567')); // false (invalid: prefix 1 not allocated)
console.log(validateNigerNumber('96123456', 'airtel')); // true (Airtel format)

2. E.164 Number Formatting for Niger

Format Niger numbers consistently in E.164 international format to improve user experience:

function formatNigerNumber(number, format = 'international') {
  const cleaned = number.replace(/\D/g, '');

  // Extract local number
  let local = cleaned;
  if (cleaned.startsWith('00227')) {
    local = cleaned.slice(5);
  } else if (cleaned.startsWith('227')) {
    local = cleaned.slice(3);
  }

  if (!/^[2-9]\d{7}$/.test(local)) {
    return number; // Return as is if invalid format
  }

  switch (format) {
    case 'international':
      return `+227 ${local.slice(0, 2)} ${local.slice(2, 5)} ${local.slice(5)}`;
    case 'national':
      return `${local.slice(0, 2)} ${local.slice(2, 5)} ${local.slice(5)}`;
    case 'e164':
      return `+227${local}`; // E.164 format for storage
    default:
      return number; // Return original if format is unknown
  }
}

// Example usage
console.log(formatNigerNumber('+22796234567', 'international')); // +227 96 234 567
console.log(formatNigerNumber('96234567', 'national')); // 96 234 567
console.log(formatNigerNumber('96234567', 'e164')); // +22796234567

3. Error Handling

Handle errors properly to prevent application crashes and provide user feedback:

class NigerPhoneNumberError extends Error {
  constructor(message, number) {
    super(message);
    this.name = 'NigerPhoneNumberError';
    this.number = number;
  }
}

function validateWithErrorHandling(number) {
  if (!number) {
    throw new NigerPhoneNumberError('Phone number is required.');
  }

  const cleaned = number.replace(/\D/g, '');

  // Handle international prefix
  let local = cleaned;
  if (cleaned.startsWith('00227')) {
    local = cleaned.slice(5);
  } else if (cleaned.startsWith('227')) {
    local = cleaned.slice(3);
  }

  if (!/^[2-9]\d{7}$/.test(local)) {
    throw new NigerPhoneNumberError('Invalid Niger phone number format. Expected 8 digits starting with 2-9.', number);
  }

  return true;
}

// Example usage (within a try...catch block)
try {
  validateWithErrorHandling('+22796234567');
  console.log("Phone number is valid.");
} catch (error) {
  if (error instanceof NigerPhoneNumberError) {
    console.error(error.message, error.number);
  } else {
    console.error("An unexpected error occurred:", error);
  }
}

Best Practices

• Storage: Store numbers in E.164 international format (+22796234567) for consistency and simplified processing. E.164 is the standard format for international telecommunications.
• Display: Use national format (XX XXX XXX) for domestic contexts and international format (+227 XX XXX XXX) for international contexts. Consider user locale for automatic formatting.
• Input Fields: Provide clear instructions on expected format. Use input masking to guide users as they type (e.g., +227 XX XXX XXX).
• Validation: Validate both format and prefix ranges. Prefix 1 is not allocated in Niger's numbering plan.
• Performance: Cache validation patterns and compiled regex for high-volume operations. Pre-compile regex patterns at application startup.
• Carrier Detection: Use prefix-based carrier detection (96=Airtel, 93=Moov, 94=Zamani, 83=Niger Telecoms) for routing optimization.

Security Best Practices for Phone Number Handling

When handling Niger phone numbers in your application, implement these security measures:

• Input Sanitization: Always sanitize and validate phone numbers on both client and server side. Remove all non-digit characters except + before processing.
• Rate Limiting: Implement rate limiting on phone validation/verification endpoints to prevent abuse (e.g., max 5 attempts per hour per IP).
• PII Protection: Treat phone numbers as Personally Identifiable Information (PII). Comply with Niger's Law n°2022-59 on personal data protection.
• Encryption: Store phone numbers encrypted at rest using AES-256 or equivalent. Use TLS 1.2+ for transmission.
• Access Control: Implement role-based access control (RBAC) for phone number data. Log all access attempts.
• SMS Verification Security: Use time-limited OTP codes (5-10 minutes expiry). Implement exponential backoff for failed verification attempts.
• Data Minimization: Only collect and retain phone numbers when necessary. Document retention policies and implement automatic deletion.
• Audit Logging: Maintain audit logs of all phone number access, modifications, and verification attempts for compliance.

Frequently Asked Questions (FAQ)

What is Niger's country code for international calls?

Niger uses country code +227 for all international calls. Format international numbers as +227 followed by the 8-digit local number. For example, a mobile number 96 234 567 becomes +227 96 234 567 in international format or +22796234567 in E.164 format for storage.

How do I validate Niger phone numbers with regex?

Validate Niger phone numbers using the regex pattern ^[2-9]\d{7}$ for national format (8 digits starting with 2-9). For international format, use ^(\+227|00227)[2-9]\d{7}$. Mobile numbers use prefixes 93 (Moov), 94 (Zamani), 96 (Airtel), or 83 (Niger Telecoms) and can be validated with ^9[3-6]\d{6}$ or ^83\d{6}$. Remove non-digit characters before validation.

What are the major mobile operators in Niger?

The major mobile operators are Airtel Niger (formerly Celtel, 44.5-48% market share, prefix 96), Zamani Telecom (26-30% market share, prefix 94), Moov Niger (20% market share, prefix 93), and Niger Telecoms (~6% market share, prefix 83 for mobile). All operators are regulated by ARCEP under Law 2018-47 of July 12, 2018.

What format do Niger mobile numbers use?

Niger mobile numbers use 8 digits with prefixes 93, 94, 96, or 83 for major operators. Formats: 96 XXX XXX (Airtel), 93 XXX XXX (Moov), 94 XXX XXX (Zamani), 83 XXX XXX (Niger Telecoms). International format adds country code: +227 96 234 567. Store numbers in E.164 format: +22796234567.

How do I implement E.164 formatting for Niger numbers?

Implement E.164 formatting by removing non-digit characters, extracting the 8-digit local number (removing international prefixes 00227 or 227), validating the format ^[2-9]\d{7}$, then prepending +227. Example: 96-234-567 becomes +22796234567. Use this format for database storage and API transmission.

What are Niger's emergency phone numbers?

Niger's emergency numbers are 17 (Police), 18 (Fire Brigade), 15 (Medical Emergency/Ambulance), and 112 (General Emergency across all operators). Configure your application to recognize these short codes and prioritize them for emergency service access. These numbers work from all phones, including mobile and fixed lines.

What is ARCEP and what does it regulate?

ARCEP (Autorité de Régulation des Communications Électroniques et de la Poste) is Niger's independent telecommunications regulatory authority, created by Law 2018-47 of July 12, 2018. ARCEP regulates all telecom operators, manages number allocations, enforces quality standards (with fines up to 1.36 billion CFA francs for violations), and provides e-services for license applications and number reservations at www.arcep.ne.

How long are Niger phone numbers?

Niger phone numbers are 8 digits in national format (e.g., 96 234 567) and 11 digits in international format including country code +227 (e.g., +227 96 234 567). Fixed-line numbers use prefixes 2-7 (primarily 20-21 for geographic areas), while mobile numbers use prefixes 8-9 (93, 94, 96, 83 for major operators).

Can I use prefix 1 for Niger phone numbers?

No, prefix 1 is not allocated in Niger's numbering plan. Valid prefixes are 2-7 for geographic (fixed-line) numbers and 8-9 for mobile numbers. Attempting to validate or format numbers starting with 1 will fail. Always verify prefix allocations via ARCEP's official website for current assignments.

How do I call Niger from the United States?

To call Niger from the US, dial 011 (US exit code), then 227 (Niger country code), followed by the 8-digit local number. For example: 011-227-96-234-567 for an Airtel mobile number. Using the + format on mobile phones, dial +227 96 234 567. Remove any leading zeros from the local number.

What is the time zone for calling Niger?

Niger operates in West Africa Time (WAT), UTC+1, with no daylight saving time changes. When calling from the US Eastern Time (EST/EDT), Niger is 5-6 hours ahead. Plan calls during Niger business hours (8 AM - 6 PM WAT) which corresponds to 2-3 AM - 12-1 PM EST.

What is the difference between national and international format?

National format uses 8 digits without country code (e.g., 96 234 567), suitable for domestic use. International format includes country code +227 (e.g., +227 96 234 567), required for international calls. E.164 format removes spaces: +22796234567. Always store numbers in E.164 format for consistency across systems.

Does Niger support mobile number portability (MNP)?

As of 2025, Niger does not have an active Mobile Number Portability (MNP) system. Users cannot currently switch operators while retaining their phone numbers. This means prefix-based carrier identification (96=Airtel, 93=Moov, 94=Zamani, 83=Niger Telecoms) remains reliable. ARCEP may introduce MNP in future regulatory updates—monitor ARCEP announcements for implementation timelines. When MNP is implemented, applications should use HLR (Home Location Register) lookups instead of prefix-based carrier detection.

What are the costs for international calls and SMS to Niger?

International calling and SMS costs to Niger vary by originating country and service provider. Key considerations:

• Dialing: Use full international format +227 XX XXX XXX from outside Niger
• Typical Rates: International calls to Niger typically cost $0.50-$2.00 per minute; SMS $0.15-$0.50 per message (rates vary significantly)
• VoIP Options: Services like WhatsApp, Skype, or specialized VoIP providers often offer lower rates
• Roaming: Niger has roaming agreements with major international carriers. Check with your home operator for specific roaming rates
• Best Practice: For applications sending SMS to Niger numbers, negotiate bulk SMS rates directly with operators (Airtel, Moov, Zamani) or use aggregators

Contact operators directly for current tariffs: see ARCEP website for published operator tariffs and interconnection rates.
