Yemen Phone Numbers: Format, Area Code & Validation Guide

Yemen uses the international country code +967 for all phone calls and SMS messages. This comprehensive guide covers Yemen phone number formatting, validation code examples, and integration with mobile operators (Yemen Mobile, Sabafon, YOU, Y Telecom). Learn how to implement E.164 international standard formatting, validate Yemen mobile and landline numbers in Python and JavaScript, and navigate infrastructure challenges including conflict-related disruptions and Starlink's 2024 deployment.

Yemen Mobile Operators and Network Infrastructure

Yemen's telecommunications sector demonstrates remarkable resilience, operating despite ongoing conflict that has severely damaged infrastructure. Understanding this context is crucial when working with Yemeni phone numbers. Four major mobile network operators (MNOs) serve the market under challenging dual-governance conditions:

• Yemen Mobile: State-owned operator holding the largest market share (approximately 45%) with extensive rural coverage. First to offer CDMA services in the Middle East, currently executing nationwide CDMA-to-LTE migration.
• Sabafon: Private operator with approximately 30% market share, offering innovative service packages and competitive pricing through parent company Beyon's infrastructure resources.
• YOU (formerly MTN Yemen): Backed by international investment (Emerald International Investment LLC holds 82.8% stake as of November 2021), focusing on data services and aggressive southern 4G expansion with about 20% market share.
• Y Telecom: Fourth operator completing the market alongside three major carriers commanding over 95% of subscribers.

Critical Infrastructure Context: As of 2024–2025, conflict has irreversibly damaged over 25% of Yemen's telecommunications infrastructure, with virtually all parties targeting telecom facilities. Operators face dual taxation and regulatory compliance from both Sana'a and Aden authorities – duplicate licensing, spectrum fees, and separate compliance reports. International connectivity relies on limited inadequate gateways following Red Sea undersea cable cuts in early 2024.

Consider this competitive yet fragmented landscape when designing applications – it significantly influences network availability and performance.

Mobile Network Coverage: 2G, 3G, 4G LTE Availability

Yemen's mobile infrastructure spans multiple generations of technology, balancing coverage reach with data capacity. This layered approach provides services across diverse geographical terrains and population densities.

• 2G/GSM (Primary Coverage): Operating on 900 MHz (rural) and 1800 MHz (urban) frequencies, 2G provides the widest coverage, reaching approximately 85% of the population. Use this for reliable basic communication services.
• 3G/UMTS: Deployed on the 2100 MHz band, 3G delivers primary data service in urban areas, covering around 60% of the population. Choose this for applications requiring moderate data speeds.
• 4G/LTE: Strategically deployed in major cities, 4G uses Band 3 (1800 MHz) for capacity and Band 7 (2600 MHz) for high-capacity urban coverage. As of 2023, at least 4G signal covers approximately 56.7% of the population, with continued expansion in urban centers.

Performance Reality: Yemen has the world's slowest mobile data speeds at 3.98 Mbps (as of May 2023), with fixed broadband averaging 10 Mbps. Only 17.7% of Yemen's 34.83 million population had internet access as of January 2024. Design applications with extreme latency tolerance and offline-first capabilities.

Starlink Deployment: In September 2024, Starlink officially launched satellite internet service in Yemen under a five-year licensing agreement (ending January 2029). Initial deployment in Aden improved speeds from 10–12 Mbps to over 140 Mbps. Coverage remains limited but offers a significant alternative for high-reliability applications in Starlink-accessible areas. Pricing, availability zones, and user detection methods remain undisclosed for Yemen.

Network performance varies significantly by region and technology, with average download speeds ranging from 512 Kbps to 10 Mbps on traditional networks. Design your applications to handle these variations and provide fallback mechanisms for limited-connectivity areas.

Infrastructure Resilience

Yemen's MNOs implement several strategies to ensure network resilience:

• Redundant Systems: Distributed network architecture, multiple backup power systems, and alternative routing capabilities minimize disruptions from infrastructure damage or power outages.
• Coverage Strategy: Urban areas use multi-layer network deployment (4G/3G with 2G fallback), while rural regions prioritize 2G reliability with extended range configurations and solar-powered sites.

These measures ensure reliable communication, but anticipate potential disruptions and design accordingly.

Regulatory Framework

Yemen's telecommunications sector operates under a fragmented regulatory environment due to ongoing conflict. The Ministry of Telecommunications and Information Technology (MTIT) is the primary regulatory body, providing, developing, and expanding telecommunications and postal services, regulating radio frequency spectrum, and granting licenses per international standards.

Critical Regulatory Challenges:

1. Dual Governance: Operators must comply with separate requirements from both Sana'a-based and Aden-based authorities, resulting in duplicate licensing, spectrum fees, customs duties, and compliance reporting.
2. Northern Network Control: Houthi forces control state-run telecom networks in northern Yemen, imposing frequent internet shutdowns, extensive surveillance, and platform censorship.
3. Spectrum Management: Dynamic frequency allocation, interference monitoring, and prioritizing emergency communications remain challenging under divided authority.
4. Service Standards: Quality of Service (QoS) metrics, coverage obligations, and consumer protection guidelines are inconsistently enforced across territories.

Understand this fragmented regulatory landscape to ensure compliance and manage operational risks. The MTIT website (Arabic only) provides official information, though conflict limits access and updates.

Enhanced Security: SIM Registration

Modern security requirements mandate strict subscriber verification:

• Government ID validation
• Biometric data collection
• Address verification
• Digital identity linking

These measures enhance security and prevent fraud while introducing integration complexities. Verify data access permissions before implementing number verification features.

Yemen Phone Number Format and Structure

Yemen phone numbers follow the ITU-T E.164 international standard with country code +967. The complete format is +967[Area Code][Subscriber Number]. Using E.164 formatting ensures global interoperability and simplifies phone number validation for SMS and voice calls.

Yemen Area Codes and Phone Number Length

Yemen uses a two-digit area code system with variations in subscriber number lengths:

• Landlines: +967[1-7][6-digit Subscriber Number] (8 digits total after +967)
• Mobile numbers: +967[7][7-digit Subscriber Number] (8 digits total after +967)

For example, a Yemen mobile number might be +967771234567. When sending SMS to Yemen or making voice calls, always include the country code +967.

This structure provides clear distinction between landlines and mobile numbers for routing calls and sending SMS messages.

Yemen Phone Number Validation in Python

This Python function validates Yemen phone numbers, handling both landline and mobile formats with detailed error handling:

import re

def validate_yemen_number(phone_number):
    """Validates a Yemen phone number.

    Args:
        phone_number: The phone number to validate (string).

    Returns:
        True if the number is valid, False otherwise.
    """
    cleaned_number = re.sub(r'\D', '', phone_number)  # Remove non-numeric characters

    try:
        if re.match(r'^967[1-7]\d{6}$', cleaned_number):  # Landline
            return True
        elif re.match(r'^967[71378]\d{7}$', cleaned_number):  # Mobile
            return True
        else:
            raise ValueError("Invalid Yemen number format")
    except ValueError as e:
        print(f"Validation error: {e}")  # Log or handle the error appropriately
        return False

# Example usage:
print(validate_yemen_number("+967771234567"))  # Valid mobile number
print(validate_yemen_number("+96712345678"))  # Invalid landline number (too many digits)
print(validate_yemen_number("967771234567")) # Valid mobile number without +
print(validate_yemen_number("abc967771234567")) # Valid mobile number with non-numeric characters

Test your validation function with various inputs, including edge cases and invalid formats, to ensure robustness.

Storing Yemen Phone Numbers: Database Best Practices

Store Yemen phone numbers in your database following these practices:

• E.164 Format: Always store numbers in the international E.164 format (+967…). This ensures consistency and simplifies integration with other systems.
• Separate Fields: Store the country code, area code, and subscriber number in separate fields for more flexible querying and analysis.
• Data Type: Use a suitable data type for storing phone numbers (e.g., VARCHAR with appropriate length).

This SQL schema demonstrates these practices:

CREATE TABLE phone_numbers (
    id SERIAL PRIMARY KEY,
    country_code VARCHAR(4) NOT NULL DEFAULT '+967',
    area_code VARCHAR(2) NOT NULL,
    subscriber_number VARCHAR(9) NOT NULL, -- Accommodates both landline and mobile lengths
    full_number VARCHAR(15) GENERATED ALWAYS AS (country_code || area_code || subscriber_number) STORED -- Concatenated number for easy retrieval
);

This schema enforces the E.164 format, stores components separately, and provides a generated column for the full number. Adapt this schema to your specific needs.

Implementation Challenges and Solutions

Yemen's telecommunications infrastructure presents unique challenges. Here are common issues and their solutions:

Network Stability

Network instability can disrupt communication. Mitigate this with:

• Implement Retry Logic: If an API call fails due to network issues, retry it after a short delay. Use exponential backoff to increase the delay between retries.
• Cache Number Data: Cache frequently accessed number data to reduce reliance on real-time API calls.
• Fallback Validation Methods: If primary validation methods fail due to network issues, use fallback methods (e.g., basic format checks) to provide reasonable validation.

These strategies improve the reliability of your application despite network instability.

Cross-border Communication

When handling international calls to and from Yemen, ensure your system correctly formats numbers in the international format. This JavaScript function formats Yemen numbers:

function formatYemenNumber(number) {
  // Remove all non-numeric characters and leading "+"
  const cleaned = number.replace(/[^0-9]/g, '');

  // Add the country code if it's missing
  if (!cleaned.startsWith('967')) {
    return `+967${cleaned}`;
  } else {
    return `+${cleaned}`;
  }
}

// Example usage:
console.log(formatYemenNumber("0771234567")); // Output: +967771234567
console.log(formatYemenNumber("+967771234567")); // Output: +967771234567
console.log(formatYemenNumber("771234567")); // Output: +967771234567

This function handles various input formats, including numbers with or without the country code and leading plus sign. It removes any non-numeric characters, ensuring clean and consistent output.

Regional Variations

Yemen's telecommunications landscape varies significantly across regions. Consider these variations when designing your applications:

• Area Code Lengths: While area codes are typically two digits, prepare for potential variations or future changes.
• Service Availability: Service availability and quality differ across regions. Provide fallback mechanisms for areas with limited connectivity.
• Format Flexibility: Implement flexibility in your number formatting and validation to accommodate potential variations in number formats across regions.

Address these regional variations to improve the usability and reliability of your application for users across Yemen.

Advanced Technical Considerations

SMS and Voice API Integration Guidelines

When integrating Yemen phone numbers with SMS APIs or telecommunications services, follow these guidelines:

• Consistent Formatting: Always format numbers in the E.164 format before sending them to an API.
• Error Handling: Implement robust error handling to manage API errors and network issues.
• Rate Limiting: Be mindful of API rate limits and implement appropriate throttling mechanisms.

This Python class handles Yemen numbers in API interactions:

import re

class YemenNumberHandler:
    def format_for_api(self, number):
        """Formats a Yemen phone number for API calls."""
        cleaned = re.sub(r'\D', '', number)
        return f"+967{cleaned}" if not cleaned.startswith('967') else f"+{cleaned}"

    def validate_response(self, response):
        """Validates the API response."""
        # Implement your API-specific response validation logic here
        pass

# Example usage:
handler = YemenNumberHandler()
formatted_number = handler.format_for_api("771234567")
print(formatted_number)  # Output: +967771234567

This class provides a structured approach to formatting numbers for API calls and validating API responses. Adapt this class to your specific API integration needs. Handle potential exceptions and edge cases in your API integration logic.

Error Handling and Validation

Robust error handling is crucial for managing unexpected situations. This Python validation function demonstrates improved error handling:

import re
import logging

# Configure logging
logging.basicConfig(level=logging.ERROR)
logger = logging.getLogger(__name__)

def is_valid_area_code(area_code):
    """Checks if the area code is valid (placeholder for a more comprehensive check)."""
    # Replace with your actual area code validation logic
    return area_code in ["1", "2", "3", "4", "5", "6", "7"]


def validate_yemen_number(number):
    """Validates a Yemen phone number with enhanced error handling."""
    try:
        # Basic format validation
        if not re.match(r'^\+967\d{8,9}$', number):
            raise ValueError("Invalid Yemen number format")

        # Area code validation
        area_code = number[4:6]
        if not is_valid_area_code(area_code):
            raise ValueError("Invalid area code")

        return True
    except ValueError as e:
        logger.error(f"Validation error: {str(e)} for number: {number}")
        return False
    except Exception as e:
        logger.exception(f"An unexpected error occurred during validation: {str(e)} for number: {number}")
        return False

# Example usage
print(validate_yemen_number("+967771234567")) # Valid
print(validate_yemen_number("+967871234567")) # Invalid area code
print(validate_yemen_number("+96777123456")) # Invalid format

This function includes specific exception handling, logging capabilities, and a placeholder for comprehensive area code validation. Replace the placeholder with your actual area code validation logic. Handle edge cases specific to Yemen's telecommunications infrastructure, such as network instability and varying number formats across regions. Yemen Mobile uses CDMA technology, while other operators primarily use GSM. This technological difference impacts device compatibility and service availability. Consider these factors when designing your applications. Furthermore, the regulatory landscape in Yemen is subject to change, so stay updated on the latest regulations from the MTIT to maintain compliance.
