How to read a number

- +57Country code
- Colombia.
- 3First digit
- Colombian mobile numbers start with 3: a 3-digit mobile area code (3XX) plus a 7-digit subscriber number, 10 digits in all.
- 123456789Remaining 9 digits
- The rest of the area code plus the subscriber number. Blocks are allocated per operator, but numbers are portable, so they don’t reveal who serves it now.
Domestic format: 312 345 6789, no leading 0 — since 1 December 2021 everything is dialled as 10 digits and a landline no longer needs “03” to reach a mobile. Landlines are 60X plus 7 digits, also 10.
Number ranges & quality

|---|---|---|
3 prefix, 10 digits (3XX XXX XXXX) |
Mobile carrier | A mobile number is a 3-digit mobile area code (3XX) plus a 7-digit subscriber number, 10 in all — that's the structure in the CRC's numbering-plan notification to the ITU. Porting has existed since 29 July 2011, so 3XX doesn't identify the operator. |
60X + 7 digits |
Other | Landline range: since 1 December 2021 Colombian landlines are 10 digits too, written as 60 plus one regional digit plus 7 digits (601 for Bogotá, for instance). The same reform scrapped the “03” prefix for fixed-to-mobile calls and the long-distance carrier codes. A number starting with 60 is a landline, and sign-up platforms rarely accept one. |
Physical SIMs can sign up without issues.
Carriers & prefixes
Mobile prefixes by carrier.
Number portability applies — a prefix only shows the original carrier.
Porting rules in full
Mobile porting started operating on 29 July 2011 under CRC Resolution 2355 of 2010, and both prepaid and postpaid can use it. The limit was 5 days at first and came down to 3 days in August 2012; the rules now sit in Chapter 6, Title II of CRC Resolution 5050 of 2016. After more than a decade of porting, a 3XX prefix tells you nothing about the operator, so there is no table here.

Claro Mobile carrier
Formerly Comcel — the ITU's record of Colombia's numbering plan still lists this one as CELULAR COMCEL.
-
Tigo Mobile carrier
Owned by Millicom. On 27 January 2026 Millicom won EPM's remaining shares in UNE EPM (Tigo Colombia) at public auction, closing on 29 January.
-
Movistar Mobile carrier
Formerly Telefónica's Colombia Telecomunicaciones (Coltel). Millicom bought 67.5% on 6 February 2026 and took the state's remaining 32.5% on 27 April 2026. So Tigo and Movistar in Colombia are now one company behind two brands — don't treat them as two independent choices.

WOM Mobile carrier
The fourth operator with its own network.
