The Argentina country code is +54 — reaching Latin America's 3rd-largest economy + 46 million Argentinians across 23 provinces + the autonomous city of Buenos Aires, plus ~60 million mobile subscriptions across Personal, Movistar Argentina, Claro Argentina. The land of tango, Messi + Mercado Libre.
Argentina was assigned +54 by the ITU in 1949 — placing it in zone 5 with the rest of Latin America. The Argentine numbering system has a unique quirk for mobiles — a leading "9" required for international mobile dialing.
Argentina has used the +54 country code since 1949, when the ITU placed it in zone 5 alongside Brazil +55, Mexico +52, Cuba +53, Chile +56, Colombia +57 + most of Latin America. The "4" suffix was the fourth single-digit slot in zone 5 — Argentina got one of the shortest LatAm codes.
Argentina's telecom industry is regulated by ENACOM (Ente Nacional de Comunicaciones, founded 2016, replacing AFTIC + CNC). Three major mobile carriers operate: Personal (~22M subs, owned by Telecom Argentina), Movistar Argentina (~18M, owned by Telefónica), Claro Argentina (~20M, owned by América Móvil). All are GSM/LTE/5G — Argentina deployed 5G in 2023.
Argentina has a unique mobile-dialing rule: to call a mobile from <b>outside Argentina</b>, you must add a <b>9</b> between the country code + area code (so +54 <b>9</b> 11 XXXX XXXX for Buenos Aires mobile, not +54 11 XXXX XXXX). Domestically, mobiles are dialed as 011 15 XXXX XXXX. This is the only country with this specific quirk.
Argentina is the only country where mobile dialing differs internationally vs domestically. Domestically, Argentinian mobiles are dialed as 011 15 XXXX XXXX (with a "15" between area code + subscriber, indicating mobile). Internationally, you replace the "15" with a "9" placed BEFORE the area code — so the same number becomes +54 9 11 XXXX XXXX from abroad. This unique convention was set by SECOM (now ENACOM) in 2002 to distinguish mobile billing.
An Argentine phone number in international format is written as +54 [área] [local] for landlines, or +54 9 [área] [local] for mobiles. For example, +54 11 4321 1000 for a Buenos Aires landline, or +54 9 11 1234 5678 for a Buenos Aires mobile (note the "9" between +54 and 11).
Major Argentine area codes: 11 Buenos Aires (the city + Greater Buenos Aires AMBA). 351 Córdoba. 341 Rosario. 261 Mendoza. 221 La Plata. 381 Tucumán. Domestically, all Argentinian numbers start with 0 (national trunk prefix) — dropped when dialing internationally.
From the Obelisco in Buenos Aires to the glaciers of Ushuaia, every Argentine number lives behind a +54. Pick the código de área that matches your customer city.
Every country uses a different international exit code before the +54 Argentina country code. From any mobile, the + symbol replaces the exit code automatically — so +54 11 4321 1000 works worldwide. For mobiles, insert "9" between +54 and the area code (e.g. +54 9 11 1234 5678).

Argentine mobiles need the "9" inserted between +54 and the area code — +54 9 AC NNNN NNNN (e.g. +54 9 11 1234 5678). This is unique to Argentina. The leading 0 is always dropped from abroad.
