Area Code 634 – Aljawf

Overview of Yemen's +967 634 Geographic Code

The international dialing code +967 634 corresponds to a geographic numbering area within the Republic of Yemen, specifically allocated to the Al Jawf Governorate (also spelled Al-Jawf or Aljouf). This code is part of Yemen's national numbering plan, which adheres to the ITU-T E.164 standard. The prefix 634 serves as the National Destination Code (NDC) for fixed-line telephone services within this governorate, routing calls to the public switched telephone network (PSTN) infrastructure serving the region.

Geographic Coverage and Administrative Jurisdiction

Al Jawf Governorate is located in the northeastern part of Yemen, bordering Saudi Arabia to the north. The administrative center is the city of Al Hazm, which is the primary hub for telecommunications in the governorate. Other significant towns and districts covered under this code include Al Maton, Khabb wa ash Sha'af, and Al Humaydat. The code is geographically fixed, meaning it is tied to the physical telephone exchanges in these areas, and is not portable across different regions of Yemen.

Dialing Formats and Caller Instructions

When calling a fixed-line number in Al Jawf from abroad, the international format is: +967 634 XXX XXX (where X represents the subscriber's local number). The total number of digits after the country code is typically 9, including the NDC. For example, a local number might be 634 123 456, which would be dialed internationally as +967 634 123 456.

For callers within Yemen, the national trunk prefix 0 is used before the area code. Thus, to call from Sana'a or any other governorate, you would dial: 0 634 XXX XXX. However, if you are calling from within the same Al Jawf area, you may only need to dial the local subscriber number, depending on the local dialing procedures. It is always recommended to use the full national format to avoid misrouting.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for Al Jawf; the 634 code is exclusively assigned to this governorate. However, due to the ongoing telecommunications expansion, it is advisable to check with your service provider for any recent changes. The code is used for both residential and business fixed lines, and it supports standard PSTN services, including fax and dial-up internet, though most users now rely on mobile and VoIP services.

For international callers, it is important to note that Yemen's country code is +967, and the international exit code from most countries is 00 or 011 (e.g., from the US, you would dial 011 967 634 XXX XXX). Ensure you have the correct international prefix for your country.
