Area Code 259 – Clonbrook/Unity

Overview of Guyana Area Code 259

Area code 259 is a geographic destination code within the Republic of Guyana's national numbering plan, assigned to the region encompassing Clonbrook and Unity, two adjacent communities situated along the East Coast Demerara corridor in the Demerara-Mahaica administrative region. This area lies approximately 20 kilometers east of Georgetown, the national capital, and forms part of the densely populated coastal belt where the majority of Guyanese reside.

Geographic Coverage and Administrative Context

The 259 prefix serves the telephone exchanges in Clonbrook and Unity, as well as nearby villages such as Victoria, Belfield, and Good Hope, which are interconnected within the same local calling area. Administratively, these communities fall under the purview of the Neighbourhood Democratic Council (NDC) of Unity, which oversees local governance. The region is primarily residential, with a mix of agricultural activity and small-scale commerce, and is well-connected by the public road network and the East Coast Railway alignment, facilitating communication with Georgetown and other major towns.

Dialing Formats and Caller Instructions

For local callers within Guyana, the subscriber number is typically seven digits, with the area code 259 being an integral part of the national significant number (NSN). To place a call from another area code within Guyana, you must dial the full NSN: 259 followed by the four-digit subscriber line, for example, 259-1234. However, when calling from a mobile phone within Guyana, it is common practice to include the country code and area code, even for domestic calls, due to the structure of the mobile network.

For international callers, the correct format is: +592 259 XXXX, where +592 is Guyana's country calling code, 259 is the area code, and XXXX is the local four-digit number. For instance, a call from the United States to a fixed line in Clonbrook would be dialed as 011 592 259 1234 (from a landline) or +592 259 1234 (from a mobile phone).

Numbering Plan Considerations

Guyana's numbering plan is administered by the Guyana Public Utilities Commission (PUC) and follows the ITU-T E.164 recommendation. The country code +592 is allocated to Guyana, and the national destination code (NDC) for geographic areas is the first three digits after the country code. The 259 area code is part of the geographic numbering scheme, and there are currently no overlay codes in this region; the area code is mandatory for all calls, including local calls, as Guyana uses a closed dialing plan. This means that even within the same exchange, callers must dial the full seven-digit number.

As the country continues to develop its telecommunications infrastructure, including the migration to IP-based networks, the numbering plan may undergo changes. However, as of the latest update, area code 259 remains the designated code for Clonbrook and Unity, ensuring reliable connectivity for residents and businesses in this growing region.
