Area Code 64 – Goiás

Overview of Area Code +55 64

Area code 64 is a geographic National Destination Code (NDC) assigned to the central-western Brazilian state of Goiás under the country calling code +55. It serves a significant portion of the state, including the capital Goiânia and its metropolitan region, as well as several other municipalities. This code is used for both fixed-line (PSTN) and mobile services, although mobile numbers are non-geographic in nature and can be ported across different area codes within Brazil.

Geographic Coverage and Administrative Jurisdiction

The 64 area code covers the central and southern regions of Goiás, including the state capital and major cities such as Aparecida de Goiânia, Anápolis, Rio Verde, and Itumbiara. It is one of several area codes in Goiás; other codes like 61 (Brasília and surrounding areas), 62 (northern Goiás), and 65 (Mato Grosso) serve neighboring regions. The administrative jurisdiction falls under the Brazilian National Telecommunications Agency (ANATEL), which oversees numbering allocation and local dialing rules.

Dialing Formats and Caller Instructions

For local calls within the same area code, Brazilian users typically dial only the eight-digit subscriber number (or nine digits for mobile). However, for international callers, the full international format is required: +55 64 XXXX-XXXX for fixed lines or +55 64 9XXXX-XXXX for mobile numbers. For example, a fixed line in Goiânia might be dialed as +55 64 3212-3456, while a mobile number would appear as +55 64 99123-4567. When calling from another Brazilian area code, you must dial the national trunk prefix 0 followed by the carrier code (e.g., 0XX64), but from abroad, simply use +55 64.

Overlay and Numbering Considerations

Currently, there is no overlay code for 64; it is the sole area code for its region. However, due to growing demand, ANATEL has implemented number pooling and may introduce additional digits in the future. Mobile numbers in Brazil are nine digits long, starting with '9', and are not tied to a specific geographic location—they can be ported to other area codes. Fixed-line numbers are eight digits long and are geographically assigned. For international callers, it is essential to omit the leading '0' of any national trunk prefix and to use the country code +55.

Practical Tips for Callers

When dialing from outside Brazil, always replace the '+' with your international access code (e.g., 011 from the US). Ensure you have the correct number of digits: fixed lines have 8 digits, mobiles have 9. If you are unsure whether a number is fixed or mobile, note that mobile numbers always start with '9' after the area code. For VoIP users, the same international format applies. Always verify the current dialing rules with your service provider, as carrier-specific prefixes may be required for domestic long-distance calls.
