Area Code 27 – North Region

Geographic Coverage and Administrative Jurisdiction

The area code 27 is a geographic National Destination Code (NDC) assigned to the North Region of Mauritius. This region falls under the administrative jurisdiction of the Pamplemousses District and includes key localities such as Triolet, Pamplemousses, Grand Baie, and Cap Malheureux. The code serves both residential and business subscribers within this northern part of the island, which is known for its tourism infrastructure and agricultural activity.

Dialing Formats and Number Structure

Mauritian fixed-line numbers follow the ITU-T E.164 standard with a total length of 8 digits when dialed locally, excluding the trunk prefix '0'. For the North Region, the national significant number (NSN) comprises the NDC '27' followed by a 6-digit subscriber number. The local dialing format is 27XX XXXX (or 27XXXXXX without spacing). When calling from abroad, you must use the international format: +230 27XX XXXX. For example, a number in Triolet might be +230 27 123 456 (fictional).

Caller Instructions

• Local callers (within Mauritius): Dial the 8-digit number directly: 27XX XXXX. No trunk prefix is required for calls within the same NDC, but if you are calling from a different region, you still dial the same 8-digit number.
• International callers: Dial your country's exit code (e.g., 00 from Europe, 011 from North America), then 230 (Mauritius country code), followed by 27XX XXXX.

Overlay and Numbering Considerations

As of the latest ITU-T national numbering plan, Mauritius has not implemented overlay codes for geographic areas. The '27' prefix is exclusively assigned to the North Region, and no overlay is currently active. However, number portability is available for fixed-line services, meaning a subscriber may retain their number even if they move to a different operator, but the geographic significance remains tied to the original location.

Regulatory and Technical Notes

The allocation of geographic codes is managed by the Information and Communication Technologies Authority (ICTA) of Mauritius. These codes are used for PSTN and VoIP fixed-line services. For VoIP providers, the geographic code still applies, but calls are routed over IP networks. Emergency services (police: 999, ambulance: 114) are accessible without area codes. When dialing from a mobile phone in Mauritius, you may need to include the '0' trunk prefix if your mobile network requires it, but typically national dialing is 8 digits.
