Area Code 28 – North Region

Geographic Coverage and Administrative Jurisdiction

The +230 28 prefix is a geographic National Destination Code (NDC) assigned to the North Region of Mauritius. This area encompasses the northern coastal and inland districts of the island, including the popular tourist hubs of Grand Baie, Pereybère, and Cap Malheureux, as well as the administrative villages of Pamplemousses, Triolet, and Goodlands. The region is part of the Republic of Mauritius, which follows the ITU-T E.164 numbering plan, and the prefix is managed by the Information and Communication Technologies Authority (ICTA).

Dialing Formats and Caller Instructions

Within Mauritius, calls to landlines in the North Region require dialing the full national significant number (NSN), which is 7 digits long and begins with the prefix '28'. For example, a local caller would dial 28XXXXX (where XXXXX represents the subscriber number). International callers must include the country code and drop the leading trunk prefix '0' (if used domestically). Thus, a call from abroad would be formatted as +230 28XXXXX. For instance, to reach a business in Grand Baie with the subscriber number 12345, an international caller would dial +230 2812345.

Numbering and Overlay Considerations

Mauritius operates a closed numbering plan, meaning the NSN length is fixed at 7 digits for all geographic numbers. The '28' prefix is part of a range of NDCs allocated for fixed-line services in the north, and there are no overlay codes currently in effect. Subscriber numbers within this prefix are typically assigned to residential and business lines connected to the PSTN, as well as to VoIP adapters that use geographic numbers. When dialing locally, the trunk prefix '0' is often used before the NDC (e.g., 0 28XXXXX), but this is not required for international calls.

Technical and Regulatory Notes

Number portability is available in Mauritius, allowing subscribers to retain their numbers when switching between fixed-line operators, provided the service remains within the same geographic area. The '28' prefix is not associated with any mobile network operator; mobile numbers in Mauritius use distinct prefixes such as '5' and '7'. For callers, it is important to note that calls to geographic numbers are typically charged at standard local rates, while international calls incur additional tariffs. Businesses in the North Region often use these numbers for customer service and administrative lines, and they are widely recognized as local points of presence.
