Area Code 633 – Maareb

Overview of Area Code 633 (Maareb, Yemen)

Area code 633 is a geographic National Destination Code (NDC) assigned to the Maareb Governorate in the Republic of Yemen. Under the ITU-T E.164 international numbering plan, the full country calling code for Yemen is +967. When dialing a fixed-line subscriber in Maareb from abroad, you must use the international format: +967 633 XXX XXX (or the local 9-digit national significant number, which includes the NDC and the subscriber number). Within Yemen, callers dial the area code without the leading international access code, typically as 0 633 XXX XXX (the leading 0 is a trunk prefix used for domestic calls).

Coverage and Administrative Jurisdiction

Maareb (also spelled Marib) is the capital of the Maareb Governorate, located in the eastern highlands of Yemen. The area code 633 covers the city of Maareb and its surrounding districts, including key administrative and commercial zones. The governorate is strategically important due to its oil and gas resources and its location along major trade routes. Fixed-line services in this region are primarily provided by the state-owned incumbent operator, Yemen Public Telecommunications Corporation (PTC), which operates the PSTN infrastructure. The geographic nature of the code means that the number is tied to a physical exchange, and the tariff for calling a 633 number is typically based on the distance and the operator's national pricing plan.

Dialing Formats and Instructions

• International call from abroad: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), followed by Yemen's country code 967, then the area code 633 (without the leading 0), and the subscriber's 6-digit local number. Example: 00 967 633 123456.
• Domestic call from within Yemen (outside Maareb): Dial the trunk prefix 0, then 633, and the 6-digit local number. Example: 0 633 123456.
• Local call within Maareb: In many cases, you can dial the 6-digit subscriber number directly without the area code, but this depends on the local exchange configuration. For clarity, always use the full national format 0 633 123456.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletin, there is no overlay code for Maareb; the 633 code is unique to this geographic area. However, due to network expansions and the introduction of VoIP services, some numbers may be routed over IP networks, but the geographic significance remains for emergency services and number portability. Callers should be aware that due to the ongoing situation in Yemen, network availability and routing may be affected, and it is advisable to confirm with your service provider for the most reliable dialing instructions.
