Overview

CLI routes to Argentina

A CLI route to Argentina is a wholesale path that keeps the caller ID you send intact all the way to the handset. CLIRoutes only places CLI-tier traffic on paths that passed CLI test calls on Argentina’s main networks, and removes paths that stop passing.

Argentine CLI routes carry your authorised Buenos Aires or regional number on Personal, Claro and Movistar. We test fixed and mobile destinations separately because their E.164 formats differ.

Argentina is a significant nearshore destination for Spanish-language collections and customer care. Mobile dialing format is the most common cause of failed calls on new routes.

+54 followed by a 10-digit national number; mobiles add a 9 after the country code in E.164.

Caller ID rules in Argentina

A practical summary for operations teams, not legal advice. Confirm current requirements with counsel before you launch.

Last reviewed

Caller-ID presentation

Callers must present a valid number. Law 26.951 created the Registro Nacional No Llame, and telemarketing to registered numbers is prohibited. ENACOM administers the numbering plan.

Registro Nacional No Llame

Law 26.951 created the national Do Not Call registry. Telemarketers must check it before calling consumers, and fines apply per call.

Personal data (Law 25.326)

The Personal Data Protection Law, supervised by the AAIP, applies to lead lists and recordings.

Consumer defence

The Consumer Defence Law gives consumers a right to clear information about the caller and the offer at the start of the call.

Calling hours

The National Do Not Call Registry framework and consumer rules discourage calls outside 9am–8pm.

Dialing & setup

Dialing Argentina correctly

  • Mobiles: +54 9, then the area code without 0, then the number without 15. 011 15 1234 5678 becomes +54 9 11 1234 5678.
  • Area codes are 2–4 digits and the total national number is always 10 digits.
  • Argentina is on UTC−3 all year.
  • Scrub consumer lists against No Llame and keep evidence of each scrub.

Caller ID best practice

Present an Argentine number you hold, usually Buenos Aires (+54 11). Keep the CLI in the correct national format for its type, because mobile and fixed numbers are written differently.

FAQ

Argentina CLI routes: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Why do my Argentine mobile calls fail?

In E.164, Argentine mobiles need a 9 after +54: +54 9 11 xxxx xxxx. The national format (011 15 xxxx xxxx) does not work on international routes.

Do I need to scrub against No Llame?

Yes, for marketing calls to consumers. Download the registry regularly and keep evidence of each scrub.

Should I drop the 15 from Argentine mobile numbers?

Yes. In international format the 15 is removed and a 9 is added after +54. Leaving the 15 in or forgetting the 9 makes the call fail.

How long are Argentine area codes?

Two to four digits. The area code and subscriber number always add up to 10 digits, so a 4-digit area code means a 6-digit subscriber number.

Does Argentina change clocks?

No. Argentina has stayed on UTC−3 all year since 2009.

Which caller ID can I present on Argentina calls?

Only numbers you own or are authorised to use. Present an Argentine number you hold, usually Buenos Aires (+54 11). Keep the CLI in the correct national format for its type, because mobile and fixed numbers are written differently.
