Region vs. Telephone Area
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.
A code listed beside a city reflects a featured numbering association; it does not assert that every community in Buenos Aires Province uses that code or that the code stops at the administrative border.
