Area Code 57 – Damietta

Overview of Egypt's Area Code 57

Area code 57 is the National Destination Code (NDC) assigned to the Damietta Governorate in the Arab Republic of Egypt. This geographic code is part of Egypt's national numbering plan, which adheres to ITU-T E.164 recommendations. Damietta is located in the northeastern part of the country, along the Mediterranean coast, and is known for its port, furniture industry, and agricultural activities. The code serves the city of Damietta (also known as Dumyat) and its surrounding districts, including New Damietta, Ras El Bar, and Kafr Saad.

Dialing Formats

When calling a fixed-line number in Damietta, the international dialing format is:

• From abroad: +20 57 XXX XXXX (replace X with the local subscriber number).
• From within Egypt: 0 57 XXX XXXX (using the national trunk prefix '0').

For example, a typical Damietta landline number might be +20 57 234 5678 when dialed internationally, or 057 234 5678 domestically. The local subscriber number is typically 7 digits long, but the total length of a national significant number (NSN) is 9 digits, including the NDC.

Geographic Coverage and Administration

Damietta Governorate is administratively divided into several cities and markaz (centers). The area code 57 covers all fixed-line services within the governorate, including the capital city of Damietta, the industrial zone of New Damietta, and the coastal resort of Ras El Bar. The governorate is bordered by the Mediterranean Sea to the north, Lake Manzala to the east, and the Nile's Damietta branch to the west. This geographic allocation ensures that calls are routed to the correct central office exchange within the governorate.

Caller Instructions

For local callers within Damietta: If you are calling from another fixed-line number in the same governorate, you may need to dial only the local subscriber number (7 digits) without the area code, depending on your telephone operator's local dialing plan. However, for clarity and consistency, it is recommended to always use the full national format (0 57 XXX XXXX) when dialing from a mobile phone or from a different region.

For international callers: When dialing from outside Egypt, you must first dial the international access prefix of your country (e.g., 00 or +), followed by Egypt's country code +20, then the area code 57 (without the leading '0'), and finally the local subscriber number. For example, a caller from the United States would dial 011 20 57 234 5678.

Overlay and Numbering Considerations

As of the latest ITU-T operational bulletins, Egypt has not introduced overlay codes for Damietta; the area code 57 remains exclusive to the governorate. However, with the growth of telecommunications services, the government has implemented number portability, allowing subscribers to retain their numbers when switching operators. This does not affect the geographic significance of the code.

For businesses and individuals in Damietta, it is essential to display numbers in international format on websites and communications to facilitate global reach. Always verify the current dialing procedures with your service provider, as local dialing rules may vary.
