Area Code 6010 – Cundinamarca

Overview of Colombia's 6010 Geographic Prefix

The +57 6010 prefix is a geographic National Destination Code (NDC) assigned to the Cundinamarca department in Colombia, with its primary service area centered on the capital district of Bogotá. This prefix is part of the national numbering plan administered by the Comisión de Regulación de Comunicaciones (CRC) under ITU-T E.164 guidelines. As a geographic code, 6010 is used for fixed-line PSTN and VoIP services that are physically located within the assigned region, although number portability allows subscribers to retain their numbers when switching providers.

Coverage and Administrative Jurisdiction

The 6010 prefix covers the Bogotá Capital District and the surrounding municipalities within Cundinamarca, including Soacha, Chía, Cota, and La Calera. This area is Colombia's economic and political hub, hosting major government institutions, corporate headquarters, and residential zones. The prefix is allocated for local fixed-line services, distinguishing it from mobile prefixes (e.g., 310, 320) that are non-geographic and not tied to a specific region.

Dialing Formats and Caller Instructions

For local callers within the 6010 area, the national format requires dialing the three-digit area code (601) followed by the seven-digit subscriber number. For example, a local call to a number 6010 123456 would be dialed as 601 123456 from within Colombia. International callers must dial the full international format: +57 601 123456 (or 0057 601 123456 when using international exit codes). Note that the '0' in the area code is part of the national dialing plan and is dropped when dialing from abroad, but the prefix 6010 is often used in documentation to denote the full area code plus the first digit of the subscriber number.

Overlay and Numbering Considerations

Bogotá and Cundinamarca have implemented several overlay codes (e.g., 601, 602, 603) to expand numbering capacity, but 6010 remains a distinct prefix within the 601 area code. When dialing within the same area code, callers may omit the area code for local calls, but due to overlay, ten-digit dialing (area code + subscriber number) is recommended to avoid routing errors. The CRC has mandated that all fixed-line numbers in the region be dialed with the area code, even for local calls, to ensure consistency.

Service and Usage

Numbers under 6010 are primarily used for residential and business fixed lines, including corporate PBX systems and VoIP services. They are not designated for toll-free or premium-rate services, which use separate non-geographic codes (e.g., 018000 for toll-free). For callers outside Colombia, it is essential to use the correct country code (+57) and to verify the number length, as Colombian fixed-line numbers are ten digits in total (including the area code).
