History
Colombia replaced its former one-digit fixed-line regional indicators with three-digit codes beginning with 60. The unified format became mandatory for domestic calls in December 2021 and for incoming international fixed-line calls in February 2022.
A Colombian geographic destination code covers multiple departments. Mobile number portability also means that a 3xx prefix cannot reliably establish the current carrier or physical location.

Network interpretation
Largest Telephone Carriers
Current operator and market-share data are dynamic. This page avoids assigning a specific number to a carrier from its area code alone.
Landline
Area code 604 is a geographic fixed-line identifier. Consult Comisión de Regulación de Comunicaciones (CRC) for live allocation or licensing information.
Wireless
Wireless numbers commonly use separate non-geographic ranges. Number portability prevents reliable current-carrier identification from a prefix alone.
