Argentina numbers sit under country code +54 in an open plan. Each one has a 2-digit area or mobile prefix and an 8-digit subscriber line. That is 10 digits in all. A domestic "0" usually comes before the prefix. Drop it when you dial Argentina from abroad.
Carriers & language
3 major networks cover Argentina: Claro Argentina, Personal (Telecom), Movistar Argentina. Internet penetration is 74%. VoIP is permitted and regulated by ENACOM (Ente Nacional de Comunicaciones). Spanish is the main language and ARS is the currency. Use both when you write IVR scripts, SMS content and support hours.
Americas context
Numbering across the Americas mixes the North American Numbering Plan (+1) with national E.164 plans. Mobile and fixed-line prefixes vary from country to country.
Skipping the exit code
Reaching Argentina from the US requires the 011 exit code ahead of +54 — skip it and the call won't connect.
Keeping the national trunk "0"
That leading 0 on an Argentina number is for domestic calls only; leave it out when dialing in after +54.
Ignoring the time difference
Argentina runs on UTC-3. Check local hours before dialing so calls don't land outside business time.
