Comoros Phone Numbers: +269 Country Code Format & Validation Guide

This comprehensive guide covers the Comoros country code (+269) and telephone numbering system for developers, telecommunications professionals, and businesses making international calls. Learn phone number formats, how to dial Comoros from abroad, validation techniques with regex patterns, regulatory considerations, and implementation best practices.

Understanding the Comoros Telephone System

The Comoros archipelago, located in the Indian Ocean, operates streamlined telecommunications infrastructure. The Autorité Nationale de Régulation des TIC (ANRTIC) manages oversight, ensuring consistent standards across the three primary islands: Grande Comore, Mohéli, and Anjouan. The sector evolved from a state monopoly to a competitive market with support from organizations like the World Bank Group and IFC, resulting in improved service quality, lower prices, and increased mobile broadband penetration.

Comoros Phone Number Format: +269 Area Code Structure

Comoros uses a closed numbering plan with a 7-digit structure for National Significant Numbers (NSNs). This consistent format simplifies telecommunications implementation across the islands.

Core components:

• Country Code: +269
• National Significant Number (NSN): 7 digits
• International Prefix: 00

How to Call Comoros: International Dialing Instructions

Domestic Calls Within Comoros

Domestic dialing within Comoros is straightforward – dial the 7-digit number directly for any call type (landline to landline, mobile to mobile, or any combination). No area codes or prefixes are needed for local calls.

International Calls to and from Comoros

1. Dial 00
2. Dial the country code
3. Dial the phone number

Example: To call the United States, dial 00 1 5551234567

Comoros Phone Number Validation: Regex Patterns for Developers

Validate Comoros phone numbers accurately to ensure data integrity and prevent errors in your applications. Use these regular expressions (regex) for robust validation with the +269 country code. For background on international number formats, see our guide on E.164 phone number standards.

JavaScript validation examples:

// Complete number validation (including country code)
const fullNumberPattern = /^\+2693[234]\d{5}$/;

// National number validation (excluding country code)
const nationalNumberPattern = /^(76\d{5}|3[234]\d{5}|8\d{6})$/;

// Mobile number specific validation
const mobileNumberPattern = /^3[234]\d{5}$/;

// Geographic number validation
const geographicNumberPattern = /^76\d{5}$/;

function validateComorosNumber(phoneNumber) {
    const cleanNumber = phoneNumber.replace(/\s+/g, ''); // Remove whitespace
    return fullNumberPattern.test(cleanNumber);
}

function formatComorosNumber(phoneNumber) {
    try {
        const cleaned = phoneNumber.replace(/\D/g, ''); // Remove non-digits
        if (cleaned.length === 7) {
            return `+269${cleaned}`; // Add country code if missing
        } else if (cleaned.length === 10 && cleaned.startsWith('269')) {
            return `+${cleaned}`; // Already in international format
        } else {
            throw new Error('Invalid number format');
        }
    } catch (error) {
        console.error('Number formatting failed:', error);
        return null;
    }
}

Python validation examples:

import re

# Complete number validation (including country code)
FULL_NUMBER_PATTERN = re.compile(r'^\+2693[234]\d{5}$')

# National number validation (excluding country code)
NATIONAL_NUMBER_PATTERN = re.compile(r'^(76\d{5}|3[234]\d{5}|8\d{6})$')

def validate_comoros_number(phone_number):
    """Validate a Comoros phone number."""
    clean_number = phone_number.replace(' ', '')
    return bool(FULL_NUMBER_PATTERN.match(clean_number))

def format_comoros_number(phone_number):
    """Format a phone number to E.164 standard."""
    cleaned = re.sub(r'\D', '', phone_number)

    if len(cleaned) == 7:
        return f'+269{cleaned}'
    elif len(cleaned) == 10 and cleaned.startswith('269'):
        return f'+{cleaned}'
    else:
        raise ValueError('Invalid number format')

Comoros Telecommunications Regulations and Compliance

The ANRTIC regulates telecommunications in Comoros. Key compliance areas include:

• Number allocation
• Service quality
• Consumer protection
• Infrastructure development

Stay updated on ANRTIC regulations to ensure compliance when implementing phone number systems.

Future of Comoros Phone Numbers: Mobile Number Portability

Comoros currently lacks Mobile Number Portability (MNP). Future implementation remains possible as digital transformation initiatives continue. Monitor ANRTIC announcements for updates on MNP, new number ranges, and evolving regulations. The ongoing sector development makes understanding the Comoros numbering system critical for businesses and developers engaging with this market.
