Frequently Asked Questions
Format Yemen phone numbers using the E.164 international standard: +967[Area Code][Subscriber Number]. This format ensures compatibility with global systems and simplifies validation, crucial for cross-border communication.
Yemen landline area codes are two digits, ranging from 1 to 7, followed by a six-digit subscriber number. The complete format is +967[1-7][6-digit Subscriber Number], adhering to the E.164 standard.
Yemen uses different number lengths to distinguish between landlines (6-digit subscriber number) and mobiles (7-digit subscriber number) after the two-digit area code. This differentiation is essential for routing calls and SMS messages effectively.
Use 2G for basic communication due to its wide coverage (85% of the population). Choose 3G for moderate data speeds in urban areas (60% coverage), and 4G for high-speed data in major cities (30% coverage but expanding).
Yes, you can use regular expressions to validate Yemen phone numbers. The article provides Python examples demonstrating regular expression usage for both landline (+967[1-7]\d{6}) and mobile (+967[71378]\d{7}) number formats.
Yemen has three primary mobile network operators: Yemen Mobile (45% market share), Sabafon (30%), and YOU (formerly MTN Yemen, 25%). Understanding this competitive landscape is crucial for developers.
Implement retry logic with exponential backoff for failed API calls, cache frequently accessed number data, and establish fallback validation methods like basic format checks to mitigate network instability issues.
The Yemen Telecommunications Regulatory Authority (YTRA) governs the telecom sector, managing spectrum allocation, enforcing service quality standards, and setting consumer protection guidelines.
Store numbers in E.164 format (+967...), use separate fields for country code, area code, and subscriber number for flexible querying, and choose a suitable data type like VARCHAR with appropriate length.
Use try-except blocks in Python to catch exceptions like ValueError during format validation and area code checks, log errors using logging libraries, and handle potential edge cases.
Yemen requires government ID validation, biometric data, address verification, and digital identity linking for SIM registration. Developers need to be aware of these requirements for system integration.
Use consistent E.164 formatting for API calls, implement robust error handling for API errors and network issues, and be mindful of API rate limits by using throttling mechanisms.
Consider potential variations in area code lengths, service availability differences across regions, and implement format flexibility to handle these variations effectively.
Yemen's telecommunications operates despite ongoing conflict, influencing network availability and performance. Developers must consider this context and the varied network technologies (2G, 3G, 4G) when designing applications.

Yemen Phone Numbers: Format, Area Code & Validation Guide
This guide provides a comprehensive overview of Yemen's telecommunications landscape and phone number formatting for developers, system administrators, and telecom professionals. You'll learn about the country's mobile network operators, infrastructure, numbering structure, validation techniques, and best practices for integrating Yemen phone numbers into your applications. We'll also cover common challenges and solutions, along with advanced technical considerations for API integration and error handling.
Yemen's Mobile Ecosystem: Operators and Infrastructure
Yemen's telecommunications sector demonstrates remarkable resilience, continuing to operate despite ongoing conflict. Understanding this context is crucial for developers working with Yemeni phone numbers. The market is primarily served by three major mobile network operators (MNOs):
This competitive landscape influences network availability and performance, which you should consider when designing your applications.
Network Technologies and Coverage
Yemen's mobile infrastructure spans multiple generations of technology, balancing coverage reach with data capacity. This layered approach is essential for providing services across diverse geographical terrains and population densities.
Network performance varies significantly by region and technology, with average download speeds ranging from 512 Kbps to 10 Mbps. You should design your applications to handle these variations and provide fallback mechanisms for areas with limited connectivity. As noted by nPerf (a network performance measurement company), real-world data collected through their app provides valuable insights into actual network conditions. You can leverage this data to optimize your application's performance in different regions.
Infrastructure Resilience
Maintaining service continuity in a challenging environment requires innovative solutions. Yemen's MNOs have implemented several strategies to ensure network resilience:
These measures are vital for ensuring reliable communication, but you should still anticipate potential disruptions and design your applications accordingly.
Regulatory Framework
The Yemen Telecommunications Regulatory Authority (YTRA) governs the telecommunications sector, focusing on:
Understanding these regulations is important for ensuring compliance and providing reliable services. Additionally, the Ministry of Telecommunications and Information Technology (MTIT) plays a crucial role in developing and expanding telecommunications services. You can find more information on their website (Arabic only), as highlighted in the Additional Context.
Enhanced Security: SIM Registration
Modern security requirements mandate strict subscriber verification:
These measures aim to enhance security and prevent fraud, but they also introduce complexities for developers. You'll need to be aware of these requirements when integrating with Yemeni telecommunication systems.
Yemen Phone Number Structure and Formatting
Yemen adheres to the ITU-T E.164 international standard, which you should always use for storing and processing phone numbers. This ensures interoperability with global systems and simplifies number validation. The general format is
+967[Area Code][Subscriber Number]
.Area Codes and Number Lengths
Area Codes and number lengths is crucial for accurate validation. Yemen uses a two-digit area code system, with variations in subscriber number lengths:
+967[1-7][6-digit Subscriber Number]
+967[7, 1, 3, 7, 8][7-digit Subscriber Number]
(Note the repetition of 7, indicating potential overlap or changes in allocation)This structure allows for a clear distinction between landlines and mobile numbers, which is important for routing calls and sending SMS messages.
Number Validation in Python
Here's an improved Python function for validating Yemen phone numbers. It handles both landline and mobile formats and provides more detailed error handling:
This function now includes detailed comments, handles various input formats, and provides informative error messages. Remember to test your validation function with a variety of inputs, including edge cases and invalid formats, to ensure its robustness.
Data Storage Best Practices
When storing Yemen phone numbers in your database, consider these best practices:
