Area Code 336 – Edinburg/Port Mourant

Overview of Guyana Area Code 336

Area code 336 is a geographic National Destination Code (NDC) assigned to the Edinburg/Port Mourant region in Guyana. This area falls under the administrative jurisdiction of Region 6 (East Berbice-Corentyne), one of the country's ten administrative regions. The code serves the communities of Edinburg, Port Mourant, and surrounding localities, which are situated along the Corentyne River in the eastern part of Guyana, near the border with Suriname.

Geographic Coverage and Primary Localities

The 336 area code covers a predominantly rural and agricultural zone, with Port Mourant being a notable settlement known for its sugar industry and historical significance. Other nearby villages, such as Rose Hall, Albion, and Bush Lot, may also fall within the same NDC. The region is characterized by its flat coastal plain, crisscrossed by drainage canals, and is part of Guyana's productive rice and sugarcane belt.

Dialing Formats and Procedures

For callers within Guyana, dialing a local number in the Edinburg/Port Mourant area requires the national trunk prefix 0, followed by the area code 336 and the subscriber number. The complete national significant number (NSN) is typically seven digits, comprising the area code and a four-digit local number. For example, a local number might be formatted as 336-XXXX. To call from within Guyana, you would dial 0-336-XXXX.

For international callers, the dialing format follows the ITU-T E.164 standard: the international access prefix (e.g., + or 011 in North America), followed by Guyana's country code +592, the area code 336 (without the leading zero), and the local subscriber number. For instance, a complete international number would look like +592 336 XXXX.

Overlay Considerations and Numbering Plan

As of the latest ITU-T recommendations and Guyana's national numbering plan, there are no overlay codes for the 336 area. The country uses a closed numbering plan for geographic codes, meaning the NDC is mandatory for all calls, including local ones. The subscriber numbers within this code are four digits, providing a capacity of up to 10,000 unique numbers. However, due to the rural nature of the region, the actual utilization is lower.

Caller Instructions

• Local callers (within Guyana): Dial 0-336-XXXX for all calls to this region, even if you are calling from a nearby area.
• International callers: Dial your country's exit code (e.g., 00 or 011), then 592, then 336, then the four-digit local number. Example: +592 336 XXXX.

It is important to note that Guyana has been transitioning to a fully digital PSTN and VoIP environment. While traditional copper lines are still in use, many subscribers in the region have migrated to wireless or VoIP-based services. However, the geographic significance of the area code remains for routing and regulatory purposes.
