Area Code 620 – Amman

Overview of Jordan Area Code 620

Area code 620 is a geographic National Destination Code (NDC) assigned to the Amman Governorate, the capital and largest metropolitan area of the Hashemite Kingdom of Jordan. It is part of the Jordanian national numbering plan, which adheres to ITU-T E.164 recommendations. The code is used for fixed-line (PSTN) services within specific districts of Amman, including central business areas and surrounding residential zones. It is important to note that Jordan's capital is served by multiple geographic area codes (e.g., 6, 620, 621, 622, 623, 624, 625, 626, 627, 628, 629) to accommodate the high demand for telephone numbers in the densely populated region.

Dialing Formats

When dialing a number within Jordan that uses area code 620, the national subscriber number is typically 8 digits long, including the NDC. The full national significant number (NSN) is 9 digits (including the leading '0' for domestic calls).

• Local calls (within Jordan): Dial 0 620 XXX XXXX (the leading 0 is the trunk prefix).
• International calls from abroad: Dial +962 620 XXX XXXX (drop the leading 0).

Example: If the local number is 620 123 4567, a caller in Amman would dial 0620 123 4567, while an international caller would dial +962 620 123 4567.

Geographic Coverage and Administration

The 620 code covers specific administrative districts within the Amman Governorate, including parts of the capital municipality. It is managed by the Telecommunications Regulatory Commission (TRC) of Jordan, which oversees the allocation of numbering resources to licensed fixed-line operators, such as Orange Jordan and Umniah (fixed services). The code is geographically tied to the physical location of the subscriber's line, meaning that calls to 620 numbers are routed via the PSTN to the corresponding exchange in Amman.

Overlay and Number Portability

Jordan has implemented mobile number portability (MNP) and fixed number portability, allowing subscribers to retain their numbers when changing operators within the same service area. However, geographic codes like 620 remain tied to the Amman region; if a subscriber moves outside the area, they may be required to change their number unless the operator offers a non-geographic alternative. There is no overlay code for 620; instead, adjacent codes (e.g., 621, 622) are used for other parts of Amman.

Caller Instructions

• Local callers: Always include the trunk prefix '0' before the area code when dialing from within Jordan, even if calling from a mobile phone.
• International callers: Use the country code +962 followed by the area code without the leading '0'. Ensure you have the correct international exit prefix (e.g., 00 in most countries) before dialing.

For businesses and residents, understanding the correct dialing format is essential for ensuring reliable connectivity with Amman's fixed-line network.
