What the City Association Means
The 011 area code serves the Buenos Aires Metropolitan Area; administrative boundaries and the numbering area are not identical.
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.
