Number format and reaching a +57 number

A Colombian mobile number written in international format appears as +57 321 1234567. The +57 prefix identifies the number as Colombian, and the remaining digits identify the mobile line.

Calls and messages to a +57 number can be made over the internet using a data connection. This applies to a smartphone, tablet or computer with an internet link, rather than a traditional fixed or mobile line. Internet calling and messaging reach Colombian numbers without the need for a local SIM card or a contract with a Colombian operator.

Slashtel also sends prepaid mobile top-ups to Colombia. The operators covered are Claro, Movistar, Tigo and WOM. To add credit to a Colombian mobile line, top up a Colombia number through the Slashtel recharge page.

A caller or sender reaching a +57 number should use the full international format shown above, beginning with the +57 code. The same format applies whether the contact is made by internet call or by message over a data connection.

Colombia uses the Colombian peso for mobile credit and other payments. Spanish is used across the country, including in the capital, Bogotá. The single time zone, America/Bogota at UTC-05:00, applies nationwide, so a call or message to any Colombian number is made against the same local clock. The +57 code, the CO ISO code and the Colombian demonym all refer to this one country in South America.
