Area Code 6045 – Medellín

Overview of Area Code 6045 in Colombia

Area code 6045 is a geographic National Destination Code (NDC) assigned to the city of Medellín, the capital of the department of Antioquia, and its surrounding metropolitan area. As part of Colombia's national numbering plan, which follows ITU-T E.164 recommendations, this code is used for fixed-line (PSTN) services. Medellín is the second-largest city in Colombia and a major industrial and commercial hub, so this code serves a dense population and numerous businesses.

Geographic Coverage and Jurisdiction

The 6045 code covers the urban and suburban areas of Medellín, including municipalities such as Bello, Envigado, Itagüí, and Sabaneta, which form the Aburrá Valley metropolitan area. The administrative jurisdiction is the Mayor's Office of Medellín and the Metropolitan Area of the Aburrá Valley. This code is used for both residential and corporate fixed-line connections within this region.

Dialing Formats

When calling a number in Medellín from within Colombia, you must dial the national trunk prefix 0, followed by the area code 6045 and the subscriber number (typically 7 digits). For example, a local number might be dialed as 0-6045-XXXXXXX from other parts of Colombia. However, within the same area code, local calls may be dialed using only the 7-digit subscriber number, depending on the operator's dialing plan.

For international callers, the format is +57 6045 XXXXXXX (or +57 6045 XXXXXXX). The plus sign represents the international access code from your country, 57 is Colombia's country code, and 6045 is the area code. Note that the leading '0' is omitted when dialing from abroad.

Overlay and Numbering Considerations

Currently, there is no overlay code for Medellín; the area code 604 is the traditional code for the region. However, due to the growing demand for telecommunication services, the Colombian regulatory authority (CRC) has implemented number pooling and other measures to ensure sufficient numbering resources. The 6045 prefix is part of the 604 block, which is assigned to fixed-line services. Mobile numbers in Colombia use different prefixes (e.g., 3xx) and are non-geographic.

Caller Instructions

For local callers within Medellín, simply dial the 7-digit subscriber number. For callers from other Colombian cities, dial 0-6045-XXXXXXX. For international callers, dial +57 6045 XXXXXXX. Always check with your service provider for any additional charges or special dialing requirements, especially when calling from VoIP or mobile networks.
