54 Country Code: Argentina (+54)
Country code 54 (+54) belongs to Argentina. Argentina uses the international dialing code +54, assigned by the International Telecommunication Union (ITU) under the E.164 standard. The ISO 3166-1 alpha-2 code is AR.
You will see the same code written several ways depending on origin: +54 (universal + prefix, works from mobile), 0054 (from countries that use 00 as their international exit code — most of Europe, Asia, and Latin America), 011 54 (from the US and Canada), 0011 54 (from Australia), or the bare 54. All refer to the same Argentina country code.
Argentina uses a 2-4 digit area code followed by a 6-8 digit local number — Buenos Aires is 11 (domestic 011), Córdoba is 351, Rosario is 341. The dialing quirk that catches almost everyone: when calling an Argentine mobile from abroad you must insert a "9" between the country code and the area code (e.g. +54 9 11 1234 5678), and drop the domestic "15" mobile prefix. Landlines do not need the 9. Drop any leading 0 from area codes when dialing internationally.

Calling Argentina Successfully: Common Mistakes & Best Practices
Most failed calls to Argentina come from one of four mistakes, not from network problems. The most common is mishandling the leading 0: domestically, Argentina numbers are written with 0 at the front (e.g. 01112345678), but that 0 is the domestic trunk prefix and must be removed when calling from outside Argentina. Dial +54 followed directly by the local number without the 0.
The second is misreading the area code on landline numbers — Argentina area codes are not uniform length (Buenos Aires 11, Córdoba 351, Rosario 341), so confirm the city before dialing. The third is dialing during off-hours — Argentina uses Spanish business hours and consumer phones are usually answered between 8 AM and 9 PM local time. The fourth and most expensive mistake is assuming your US carrier's WiFi calling feature makes the call cheap. It does not — see WiFi calling vs VoIP for international calls for why.
For scam-call awareness: +54 is the legitimate Argentina country code, and most unsolicited calls from +54 numbers are legitimate calls from Argentina-based businesses, hospitals, family members, or call centers serving US customers. Caller-ID spoofing exists, so if a call from a +54 number claims to be from a US government agency, your bank, or the IRS, hang up and call the agency back on its published number. Real authorities never demand payment over the phone.
When you are ready to place a call, the cheapest reliable route is to dial +54 from your browser using Kinvo — no app, no carrier add-on, and the per-minute rate is shown before you connect so there are no bill surprises.
