Area Code 51 – Deir Ezzour

Overview of Area Code 51 in Syria

Area code 51 is a geographic National Destination Code (NDC) within the Syrian Arab Republic's national numbering plan, conforming to ITU-T E.164 standards. It is assigned to the Deir Ezzour Governorate, located in eastern Syria along the Euphrates River. The code serves the administrative center of Deir Ezzour city as well as surrounding towns and rural communities within the governorate, including Al-Mayadin, Abu Kamal, and Al-Bukamal.

Dialing Formats and Usage

For callers within Syria, the national dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a landline in Deir Ezzour, you would dial: 0 51 XXX XXXX (where X represents the local subscriber digits). Internationally, callers must use the country code +963, omit the leading trunk prefix, and dial: +963 51 XXX XXXX. This format is essential for international callers to reach fixed-line subscribers in the region.

The subscriber numbers associated with area code 51 typically consist of 6 to 7 digits, depending on the specific exchange and the operator's numbering plan. The total length of a national significant number (NSN) in Syria is generally 8 to 9 digits, including the NDC.

Geographic Coverage and Administrative Jurisdiction

Deir Ezzour Governorate is one of Syria's largest governorates by area and is strategically significant due to its oil and gas resources. The area code 51 covers not only the provincial capital but also smaller districts and villages. This geographic allocation means that the code is tied to a physical location, and numbers are primarily used for fixed-line PSTN services. However, some operators may also use this code for fixed wireless or VoIP services that are registered to a specific address within the region.

Overlay Considerations and Numbering Changes

Currently, there is no overlay code for Deir Ezzour; area code 51 remains the sole geographic code for the governorate. The Syrian Telecommunications Establishment (STE) and the Ministry of Communications and Technology regulate the numbering plan. In recent years, due to the conflict and infrastructure changes, some areas may experience service disruptions, but the numbering scheme remains officially unchanged. Callers should always verify the current status of the line, especially for business or government numbers.

Caller Instructions

• Local callers (within Syria): Dial 0 51 followed by the subscriber number. Example: 0 51 234 5678.
• International callers: Dial your country's exit code (e.g., 00 or 011), then 963 51 followed by the subscriber number. Example: 00 963 51 234 5678.
• Mobile to fixed: When calling from a Syrian mobile phone, you must include the trunk prefix 0 before the area code, just as you would from a fixed line.

Understanding the correct dialing format is crucial for ensuring successful call completion. Always use the international format (+963 51...) when storing numbers in your contacts for use abroad.
