Area Code 777 – Mabaruma/Port Kaituma

Overview of Guyana Area Code 777

Area code 777 is a geographic destination code within the Republic of Guyana's national numbering plan, designated for the country's far northwestern region. Specifically, it serves the administrative districts of Barima-Waini and parts of the Pomeroon-Supenaam, encompassing the towns of Mabaruma and Port Kaituma, as well as surrounding riverine and coastal communities. This region, bordering Venezuela and the Atlantic coast, is sparsely populated and relies heavily on both fixed-line PSTN and mobile services for connectivity.

Geographic Coverage and Administrative Jurisdiction

The 777 code covers an area that includes the regional capital Mabaruma, the mining settlement of Port Kaituma, and smaller villages such as Morawhanna, Kumaka, and Hobodia. The region is characterized by its remote location, accessible primarily by river or air, which historically made reliable telecommunications challenging. The code falls under the jurisdiction of the Telecommunications Agency of Guyana (TAG), which oversees the national numbering plan in accordance with ITU-T E.164 recommendations.

Dialing Formats and Caller Instructions

For callers within Guyana, dialing a number in the 777 area requires the national trunk prefix 0 followed by the area code and the subscriber number. The local number format is typically seven digits, composed of the three-digit area code (777) plus a four-digit subscriber line. Thus, a local call would be placed as: 0 777 XXXX.

For international callers, the correct format is: +592 777 XXXX, where +592 is Guyana's country calling code, followed by the area code and subscriber number. It is essential to omit the leading trunk prefix '0' when dialing from abroad. For example, to reach a fixed line in Mabaruma, one would dial +592 777 1234 (using a placeholder subscriber number).

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for the 777 area; it remains a unique geographic code. However, with the ongoing expansion of mobile and VoIP services, some numbers assigned to this code may be used by nomadic or non-geographic services, though the primary allocation remains for fixed-line services. Callers should be aware that while mobile numbers in Guyana typically begin with '6' or '7', the 777 code is specifically geographic and not part of the mobile numbering range.

Practical Guidance for Callers

For local callers within Guyana, ensure you include the trunk prefix '0' when dialing from a different area code. For example, a caller in Georgetown (area code 225) would dial 0 777 XXXX. For foreign callers, always use the international format +592 777 XXXX. If you experience difficulties, confirm the subscriber number length, as some numbers may have been migrated to a longer format during network upgrades. It is also advisable to check with your service provider for any special international dialing prefixes required in your country.
