Area Code 455 – Bartica

Overview of Guyana's +592 455 Geographic Prefix

The +592 455 prefix is a geographic National Destination Code (NDC) assigned to the Bartica area in Guyana. Bartica, often called the 'Gateway to the Interior,' is a riverside town located at the confluence of the Essequibo, Mazaruni, and Cuyuni rivers in the Cuyuni-Mazaruni region. This code is used for fixed-line PSTN services within this specific locality, distinguishing it from other geographic codes like Georgetown (225) or Linden (444).

Dialing Format and Number Structure

In the international format, a Bartica number is written as +592 455 XXXX, where XXXX is the local subscriber number. The full national number is 455 XXXX, with a total length of 7 digits after the country code. When dialing locally within Guyana, callers must include the NDC (455) even when calling from another landline in the same area, as per the national numbering plan. For international callers, the format is: +592 455 XXXX. For example, a typical Bartica number might be +592 455 1234.

Geographic Coverage and Administrative Jurisdiction

The 455 prefix specifically serves the town of Bartica and its immediate surrounding communities. Bartica is the capital of the Cuyuni-Mazaruni region and is an important hub for mining, logging, and river transport. The area code is administered by the Guyana Telecommunication Agency (GTA) and is allocated to the incumbent operator, Guyana Telephone and Telegraph Company (GTT), which provides fixed-line services in this region. It is important to note that this is a geographic code, meaning it is tied to a physical location, unlike mobile or non-geographic codes.

Caller Instructions and Overlay Considerations

For local callers within Guyana, dialing a Bartica number requires the full 7-digit number (455 XXXX) from any other fixed or mobile line. There is no trunk prefix '0' used in Guyana's international dialing; callers simply dial the country code followed by the NDC and subscriber number. As of now, there is no overlay code for Bartica, meaning 455 is the sole geographic code for this area. However, with the growth of VoIP and mobile services, callers should be aware that number portability may allow some numbers to be routed to different networks, but the geographic association remains.

Practical Usage and Examples

When calling from abroad, you would dial your international access code (e.g., 011 from the US or Canada), then 592, then 455, followed by the local number. For instance, to reach a business in Bartica, you might dial +592 455 7890. It is always advisable to confirm the number with the recipient, as misdialing can lead to unintended destinations. For businesses, having a 455 number establishes a local presence in Bartica, which can be beneficial for customer trust and regional operations.
