Area Code 227 – Georgetown

Overview of Guyana's +592 227 Geographic Code

The +592 227 prefix is a geographic National Destination Code (NDC) assigned to the central business district and surrounding neighborhoods of Georgetown, the capital city of Guyana. As part of the nation's E.164 numbering plan, this code routes calls to fixed-line PSTN and VoIP services within a specific exchange area. The prefix is administered by the Guyana Telecommunications Agency (GTA) and allocated to licensed fixed-line operators, primarily GTT (Guyana Telephone and Telegraph Company), which holds the dominant market share for landline services in the capital.

Geographic Coverage and Administrative Jurisdiction

Georgetown, located on the Atlantic coast at the mouth of the Demerara River, serves as the nation's political, commercial, and cultural hub. The 227 exchange area encompasses key districts such as Bourda, Lacytown, Queenstown, and the central business district along Regent Street and Avenue of the Republic. It also covers government buildings, financial institutions, and major commercial enterprises. The code is strictly geographic: it does not serve mobile or nomadic services, and its use is limited to the defined exchange boundaries. Overlay codes have not been introduced in Guyana, so 227 remains the sole NDC for this part of Georgetown.

Dialing Formats and Caller Instructions

For local callers within Guyana, dialing a 227 number requires only the seven-digit subscriber number (e.g., 227-XXXX). For international callers, the full E.164 format must be used: +592 227 XXXX. For example, a typical number might be +592 227 4567. When calling from a mobile phone, the plus sign can be replaced with the international access code (e.g., 011 from the US, 00 from most European countries). It is important to note that Guyana's numbering plan does not use trunk prefixes (such as '0' or '1') for domestic calls; therefore, the national significant number (NSN) is always seven digits for geographic numbers, with the NDC being the first three digits.

Technical and Regulatory Considerations

Fixed-line numbers under 227 are primarily used for voice calls, but they can also support fax and DSL internet services. Number portability is not yet fully implemented in Guyana, meaning that if a subscriber switches from GTT to another fixed-line provider (where available), they may need to change their number. However, the GTA has been working toward introducing local number portability in the future. For businesses, having a 227 number signals a physical presence in the capital, which can be important for customer trust and local branding. VoIP providers offering geographic numbers in Guyana must comply with GTA regulations, ensuring that calls to 227 numbers are properly routed and that emergency services (911) are accessible.
