Argentina numbering plan & how to dial
Under country code +54, Argentina numbers follow an open plan built from a 2-digit area or mobile prefix and a 8-digit subscriber line — 10 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Argentina internationally.
3 major networks cover Argentina (Claro Argentina, Personal (Telecom), Movistar Argentina), against 74% internet penetration. VoIP is permitted and regulated by ENACOM (Ente Nacional de Comunicaciones). Because Spanish is the primary language and ARS the local currency, both should inform IVR scripts, SMS content, and support hours.
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
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 a 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.
Permitted — ENACOM regulated
Regulated by ENACOM (Ente Nacional de Comunicaciones)
- VoIP providers must register with ENACOM and comply with Resolution 1523/2010 for numbering and interconnection.
- Local number portability (LNP) is mandatory; carriers must support ported number routing within regulated timelines.
- Emergency service access (911) must be maintained by all VoIP operators serving Argentine subscribers.

FAQ
Calling Argentina — frequently asked questions
Dial 011 (US exit code), then 54 (the Argentina country code), then the area or mobile prefix and subscriber number. Drop any leading domestic trunk 0 — that digit is only used for calls placed from inside Argentina itself.
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. In Argentina specifically, that's overseen by ENACOM (Ente Nacional de Comunicaciones), which sets the compliance bar Twiching's routes are built to meet.
Where locally supported, yes — Twiching's Argentina numbers can send and receive SMS in addition to voice calls. That makes a single number usable for both two-way conversations and outbound notifications.
Calls from the US to Argentina start at $0.015/min on Twiching, billed per second on Tier-1 routes. That's the same rate whether the call lands on a mobile or fixed-line number in the country.
A full national Argentina number is 10 digits after the +54 country code — a 2-digit area or mobile prefix plus a 8-digit subscriber number. Getting this length right matters: too few or too many digits and the call simply won't connect.
