Area Code 531 – Madaba

Overview of Jordan's +962 531 Geographic Prefix

The +962 531 prefix is a geographic National Destination Code (NDC) assigned to the Madaba Governorate in the Hashemite Kingdom of Jordan. Madaba, often called the 'City of Mosaics,' is located approximately 30 kilometers southwest of the capital, Amman. The prefix covers the administrative city of Madaba and its surrounding towns and villages, including areas like Dhiban, Ma'in, and the historical site of Mount Nebo. As a fixed-line service, numbers under this prefix are allocated to residential, commercial, and government landlines within this specific geographic region.

Dialing Formats and Procedures

Understanding the correct dialing sequence is crucial for both domestic and international callers.

• Domestic Calls (within Jordan): When calling a Madaba landline from any other location in Jordan, you must include the trunk prefix '0' followed by the NDC and the subscriber number. The format is: 05 31 XXX XXX (where X represents the local subscriber digits). For example, to call a number in Madaba, you would dial 05 31 234 567.
• International Calls (from abroad): Callers outside Jordan need to dial the Jordan country code (+962), followed by the NDC without the leading '0', and then the subscriber number. The format is: +962 5 31 XXX XXX. For instance, from the United States or Europe, you would dial +962 5 31 234 567.

Number Structure and Length

Jordanian fixed-line numbers, including those under the 531 prefix, follow the ITU-T E.164 standard. The complete international number consists of the country code (+962), the NDC (5 for fixed-line services in the Amman and Madaba region, followed by the 31 sub-prefix), and a 7-digit subscriber number. In total, the national significant number (NSN) is 9 digits long, excluding the trunk prefix '0'. The structure is: +962 5 31 XXX XXX.

Geographic Significance and Overlays

Madaba's 531 prefix is part of the larger 5 NDC block that also serves Amman and other central Jordanian governorates. This means that numbers beginning with 05 are not exclusively for Madaba; the following digits (31) specifically route calls to Madaba's central office. There are no overlay codes in this region, so the 531 prefix remains a direct indicator of the geographic location. For businesses, using a local Madaba number can enhance local presence and trust, while for residents, it ensures affordable local call rates within the governorate.

Caller Instructions

For local callers within Madaba, dialing just the 7-digit subscriber number may work if the call is within the same exchange, but it is always safer to dial the full 9-digit number starting with '05' to ensure proper routing. For international callers, always replace the leading '0' with the country code +962. Remember that international dialing from many countries requires an exit code (e.g., 011 from North America, 00 from most European countries) before the +962.
