Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

Numbers are portable: the General Telecommunications Law (Law 8642) makes keeping your number a user right when switching between similar providers; SUTEL uses an “All Call Query” scheme with a central database, under resolutions RCS-319-2014 and RCS-027-2021 and later amendments, and in 2026 it is tendering for a new portability database operator. We haven't confirmed the porting deadline from the text, so none is given.

  • Kölbi Mobile carrier

    The mobile brand of state-owned ICE; in SUTEL's allocations the large blocks starting with 8 are registered to ICE.

  • Liberty Mobile carrier

    Its ranges weren't confirmed from a current official allocation table, so none are listed.

  • Claro Mobile carrier

    In SUTEL's allocations many blocks starting with 7 are registered to Claro CR Telecomunicaciones.
