Argentina uses country calling code +54 and a ten-digit national significant number for ordinary telephone numbering. Geographic area codes vary from two to four digits, while the local subscriber part shortens accordingly. Drop the domestic trunk 0 after +54; mobile calls from abroad add 9 after +54 and omit the domestic 15.
The examples show a national format and the corresponding international plus format. Actual subscriber lengths can vary where noted.

City guide →Argentina’s Basic National Numbering Plan was approved in 1997 and expanded the national significant number from eight to ten digits by 31 January 1999. A staged programme in 2011–2012 changed 21 geographic area codes and lengthened their local numbers without changing the ten-digit national total.
An area code identifies an ENACOM local numbering area, not an exact address. The code alone does not reveal a subscriber or guarantee the current carrier. Fixed and mobile numbers use different international formats, so the +54 9 mobile rule must be checked before calling a mobile.
Argentina uses country calling code +54.
No. Remove the domestic trunk prefix 0 before adding +54.
No. It describes a numbering-plan association, while portability, forwarding and internet telephony can separate a number from the caller’s present location.
