Dialing into Colombia means working with an open numbering plan under country code +57: a 2-digit prefix plus a 8-digit subscriber number, 10 digits total. Locally, numbers usually carry a leading "0" that gets dropped when calling Colombia from outside the country.
Carriers & language
With 65% internet penetration, Colombia is covered by 3 major carriers — Claro Colombia, Movistar Colombia, Tigo Colombia. VoIP is permitted and regulated by CRC (Comisión de Regulación de Comunicaciones). IVR prompts, SMS copy, and business hours here should account for the local language (Spanish) and currency (COP).
Americas context
Numbering across the Americas mixes the North American Numbering Plan (+1) with national E.164 plans, so mobile and fixed-line prefixes vary from country to country.
Skipping the exit code
Colombia calls from the US need 011 first, then +57 — the exit code isn't optional.
Keeping the national trunk "0"
If a Colombia number is written with a leading 0 for domestic use, omit that 0 after the +57 country code when calling from abroad.
Ignoring the time difference
Before dialing Colombia, check the local clock — it runs on UTC-5, and off-hours calls tend to go unanswered.
