Area Code 2057 – Maroantsetra/Sainte Marie

Geographic Coverage and Administrative Jurisdiction

The area code 2057 is a geographic National Destination Code (NDC) within the Republic of Madagascar's national numbering plan, conforming to ITU-T E.164 standards. It designates the northeastern coastal region encompassing the town of Maroantsetra and the island of Sainte Marie (Nosy Boraha). Administratively, this code falls under the Analanjirofo region and serves as the primary routing identifier for fixed-line PSTN subscribers in these localities. Maroantsetra serves as a key economic hub for the region, while Sainte Marie is a prominent tourist destination, making the code essential for both local residents and international visitors requiring reliable telecommunication services.

Dialing Formats and Caller Instructions

For domestic callers within Madagascar, the number must be dialed in the national format: 020 57 XX XXX. The leading '0' is the trunk prefix used to access the national PSTN. For international callers, the country code +261 replaces the trunk prefix, and the area code is dialed without the leading zero, resulting in the format: +261 20 57 XX XXX. For example, a local call to a Maroantsetra subscriber would be placed as 020 57 123 45, while an international caller would dial +261 20 57 123 45. It is crucial to omit the initial '0' when dialing from abroad to ensure proper call routing.

Numbering Structure and Overlay Considerations

Madagascar's fixed-line numbers typically consist of 10 digits when dialed domestically, including the trunk prefix '0', the NDC (20 57), and a subscriber number of 5 to 6 digits. Currently, no overlay codes have been implemented for the 2057 area; the region maintains a single NDC. However, as the national telecommunications sector evolves, the regulatory authority may introduce additional codes or renumbering schemes. Subscribers and businesses in Maroantsetra and Sainte Marie should stay informed about potential changes to ensure uninterrupted communication.

Service Providers and Usage

Fixed-line services in this region are primarily provided by the incumbent operator, Telma Madagascar, alongside other licensed operators. These lines are used for residential, commercial, and governmental communications. Given the tourist influx in Sainte Marie, many hotels and resorts rely on these fixed lines for reservations and guest services. For travelers, understanding the correct dialing format is essential for reaching local accommodations and services. International callers should verify the current dialing procedures with their service provider, as some may require additional prefixes for international calls.
