Area Code 6015 – Bogotá

Overview of Colombia's Geographic Code 6015

In Colombia's national numbering plan, the country calling code +57 is followed by a two-digit National Destination Code (NDC) for fixed telephony. The prefix 6015 corresponds to the capital district, Bogotá, and its surrounding metropolitan area. More precisely, the NDC 60 identifies the Bogotá geographic region, and the subsequent digits, such as 15, represent a Central Office Code (COC) within that region. Thus, a complete national significant number (NSN) for a fixed line in Bogotá typically consists of the NDC (60) plus an eight-digit subscriber number, with the first two digits of that subscriber number often being 15. This results in a total NSN length of 10 digits (excluding the leading +57).

Geographic Coverage and Administrative Jurisdiction

The 6015 prefix is allocated to fixed-line services within the city of Bogotá, which serves as the capital of Colombia and the administrative center of the Cundinamarca department. The coverage area includes the urban districts of Bogotá (such as Chapinero, Usaquén, and Suba) and may extend to certain suburban areas within the Bogotá savanna. As a geographic code, it is tied to a specific physical location, and calls to 6015 numbers are routed over the PSTN or VoIP networks to the corresponding exchange in Bogotá.

Dialing Formats and Caller Instructions

For callers within Colombia, dialing a Bogotá fixed line requires the national trunk prefix '0' followed by the NDC and subscriber number. For example, to call a number with the prefix 6015, a local caller would dial 0 6015 XXX XXX. However, within Bogotá, local calls may be dialed using only the eight-digit subscriber number (e.g., 15 XXX XXX) if the caller is in the same geographic area and the number is not subject to overlay complexities. For international callers, the format is +57 6015 XXX XXX (or +57 60 15 XXX XXX). It is important to note that the leading '0' of the national trunk prefix is not included when dialing from abroad.

Overlay Considerations and Numbering Evolution

Bogotá has not implemented an overlay code for fixed lines; the NDC 60 remains the sole geographic code for the capital. However, due to the growth of mobile and VoIP services, some numbers with the 6015 prefix may be assigned to non-geographic services, but they still retain the geographic identity. Callers should be aware that while the prefix indicates a Bogotá location, the actual physical location of the called party may vary if number portability has been applied, though this is less common for fixed lines.

Practical Examples for Callers

• Local call (within Bogotá): 15 XXX XXX
• National call (from other Colombian cities): 0 6015 XXX XXX
• International call (from abroad): +57 6015 XXX XXX

When dialing from a mobile phone in Colombia, the national trunk prefix '0' is often omitted, and the call is placed as 6015 XXX XXX. Always verify the correct number length and format with your service provider, as some VoIP services may require the full international format.
