Calling Argentina from United States

Dial 011 (the United States exit code), then 54 (Argentina’s country code), then the local number with its leading 0 removed. So +54 11 4321 1234 is dialled as 011 54 11 4321 1234. From a mobile you can dial +54 directly instead of 011.
Dialling Argentina from United States: start with 011, the exit code for United States, then 54 for Argentina, then the local number with its leading 0 dropped. The diagram shows those three blocks and the leading-zero rule that catches most people out.
The + shortcut on a mobile replaces the exit code entirely, which is why it works on any SIM in any country.

Step by step

Dialing Argentina from United States

Four steps, and the third one is where almost every failed call goes wrong.

  1. 1

    Dial 011: the exit code for United States

    011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel.
  2. 2

    Dial 54: the country code for Argentina

    54 is Argentina's country calling code. It never changes and is the same no matter where you are calling from.
  3. 3

    Drop the leading 0 from the local number

    Numbers written for domestic use in Argentina begin with 0. That digit is a national trunk prefix and is not part of the number. Remove it: +54 11 4321 1234 is dialled as 11 4321 1234 after the country code.
  4. 4

    Check the local time before you dial

    Argentina is on ART (UTC−3, no DST) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

One thing about Argentina

To reach an Argentine mobile from abroad you insert a 9 after +54 and drop the domestic 15 prefix. Getting this wrong is the single most common reason calls to Argentina fail.

Frequently asked questions

How do I call Argentina from the United States?
Dial 011, then 54, then the local number with its leading 0 removed. For example, +54 11 4321 1234 is dialled as 011 54 11 4321 1234.
What is the country code for Argentina?
+54. From United States you reach it by dialling 011 first, or by dialling + directly from a mobile.
Do I include the 0 when calling Argentina?
No. The leading 0 is only used inside Argentina. Including it from abroad is the most common reason the call fails to connect.
How do I call a Argentina mobile from United States?
Exactly the same way as a landline: 011 + 54 + the mobile number without its leading 0. A Argentina mobile in international format looks like +54 9 11 4321 1234.
What is the time difference between United States and Argentina?
United States is on ET (UTC−5/−4) and Argentina is on ART (UTC−3, no DST). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
Is it cheaper to call Argentina over the internet?
Usually, yes. Carrier international rates are typically far above VoIP per-minute rates, and calling from an owned local number also means the person you are calling sees a number they can ring back.
