About Argentina Calling Code
To reach Argentina from another country, first dial the international calling code +54 — assigned by the ITU — followed by the local number. Argentina is located in South America, in South America.
The +54 prefix comes from ITU-T E.164, the numbering standard that keeps Argentina's phone network addressable from anywhere in the world. Because Argentina sits in South America, its code is grouped with the surrounding countries rather than shared randomly.
Where the +54 Calling Code Is Used
The country code +54 is assigned to Argentina, located in South America, with the capital Buenos Aires. This code is part of the international telephony numbering plan and is used for all calls made to Argentina from outside the country.
When a number is written as +54 …, the +54 prefix directs your call to the Argentina national network. After the prefix, dial the area code without its leading zero, then the subscriber number — the same pattern for landlines and mobiles.
ITU-T E.164 groups calling codes by world region; codes beginning with 5 cover the part of the world that includes Argentina, in South America. Storing numbers with +54 and omitting the domestic leading zero keeps contacts dialable from anywhere.
Argentina Phone Number Formats
The ITU E.164 format for Argentina numbers is +54 + area code + subscriber number, used for landlines and mobiles alike. Here is the general structure:
📱 Number Structure
- International format: +54 [area code] [subscriber number]
- From abroad: exit code + +54 + local number (drop the trunk prefix 0)
- Within Argentina: dial the local number directly
Numbering plans come in two shapes: open plans allow variable-length numbers with a trunk prefix, closed plans fix the length everywhere. Argentina follows the published pattern +54 (XX) XXXXXXXX. Either way the rule for calling in from abroad is identical: replace the trunk prefix with +54.
Time Zone in Argentina
The local time in Argentina follows the America/Argentina/Buenos_Aires time zone (UTC-03:00 UTC). Check the time difference before you dial so your call arrives during waking hours.
Time differences matter when calling Argentina: if it is UTC-03:00 there, a morning call from Europe may reach Buenos Aires in the afternoon, while callers in the Americas should check the offset to avoid late-night calls.
If Argentina observes daylight saving time, its UTC offset shifts by an hour twice a year. Double-check the current offset before time-sensitive calls, especially in spring and autumn.

Example: 011 +54 [area code] [number]
