Area Code 773 – Aishalton

Overview of Guyana's +592 773 Geographic Prefix

The +592 773 prefix is a geographic National Destination Code (NDC) assigned to the Aishalton area within the Upper Takutu-Upper Essequibo region of Guyana. Aishalton is a remote indigenous village located in the Rupununi savannah, near the border with Brazil. This prefix is used for fixed-line PSTN services, and it enables callers to reach landlines in this specific locality.

Geographic Coverage and Administration

The 773 code is administered under Guyana's national numbering plan, which follows the ITU-T E.164 recommendation. It serves the Aishalton township and its immediate surrounding communities. The region is characterized by its distance from the capital, Georgetown, and its limited telecommunications infrastructure, which historically relied on satellite and microwave links. The prefix is part of the geographic numbering scheme, meaning that the number itself identifies the physical location of the subscriber's line.

Dialing Formats and Instructions

For callers within Guyana, the national dialing format is 773-XXXX. When dialing from a local fixed line, you would typically dial just the seven-digit number (773 plus the four-digit subscriber number). However, from a mobile phone in Guyana, you may need to include the trunk prefix '0' before the area code, resulting in 0-773-XXXX. For international callers, the format is +592 773 XXXX (or 011 592 773 XXXX from North America). For example, to call a fixed line in Aishalton from the United States, you would dial 011 592 773 XXXX. From the UK, you would dial 00 592 773 XXXX.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Aishalton area; the 773 prefix is unique to this region. However, as Guyana's telecommunications sector evolves, especially with the expansion of mobile and VoIP services, it is essential to verify the current dialing procedures with your service provider. Number portability is not widely implemented for fixed lines in this region, so the prefix generally remains tied to the geographic location.

Caller Guidance

For local callers, ensure you have the correct four-digit subscriber number. For international callers, be mindful of time zone differences (Guyana Time, UTC-4) and potential network congestion due to the area's remote nature. It is also advisable to confirm the number with the recipient, as some lines may be shared or have limited availability.
