Area Code 636 – Maareb

Overview of Yemen's +967 636 Geographic Code

The +967 636 prefix is a geographic National Destination Code (NDC) assigned to the Maareb (Marib) governorate in the Republic of Yemen. This code is part of the national numbering plan administered by the Public Telecommunication Corporation (PTC) of Yemen, following ITU-T E.164 recommendations. The Maareb region, located in the eastern part of the country, is served by this code for fixed-line PSTN (Public Switched Telephone Network) services. It is important to note that this is a landline prefix, not a mobile code; mobile numbers in Yemen typically begin with 7 (e.g., +967 7x xxx xxx).

Dialing Format and Usage

When calling a fixed-line number in Maareb from within Yemen, subscribers must dial the trunk prefix '0' followed by the area code and the subscriber number. The national format is: 0 636 XXX XXX (where X represents the local subscriber digits). For example, a local number might be 0 636 123 456.

For international callers, the number must be dialed in full international format: +967 636 XXX XXX (or 00967 636 XXX XXX from many countries). For instance, to call a Maareb landline from the United States, you would dial: 011 967 636 123 456. From the United Kingdom, you would dial: 00 967 636 123 456.

Geographic Coverage and Administrative Context

The 636 code covers the Maareb Governorate, which includes the city of Marib and its surrounding districts. Marib is historically significant and serves as the administrative center of the governorate. The region is known for its oil and gas resources, and the fixed-line network supports government offices, businesses, and residential subscribers. As with many rural areas in Yemen, network infrastructure may be limited, and service availability can be affected by regional conditions.

Caller Instructions and Considerations

• Local callers within Yemen must always include the trunk prefix '0' when dialing any fixed-line number, even if calling from the same area code. For example, to call a Maareb number from Sana'a, you would dial: 0 636 123 456.
• International callers must replace the trunk prefix '0' with the country code +967. Do not dial the '0' when calling from abroad.
• Overlay considerations: As of the latest available data, there is no overlay code for Maareb; 636 remains the sole geographic code for the region. However, numbering plan changes may occur, so it is advisable to verify with current telecom authorities.
• Service limitations: Fixed-line services in Yemen may experience outages or reduced quality due to infrastructure challenges. VoIP services may route calls differently; always check with your service provider for specific dialing instructions.

Understanding the correct dialing format for +967 636 ensures reliable connectivity to Maareb. Whether you are a business contacting local partners or an individual reaching family, using the proper international prefix is essential.
