Argentina has 300 active geographic area codes, from 11 in Buenos Aires to four-digit codes for smaller localities. The map places each code at the head-locality listed by ENACOM and shows provincial boundaries for orientation.
How to read the map. At the country view, the map shows the broad two- and three-digit codes. Four-digit locality codes appear when you zoom in; search for one to highlight its point immediately. A dot is placed at the centroid of its ENACOM-listed locality, or at the published locality point cited below; where codes overlap or head-localities coincide, their labels share a pin. Provincial fills and borders provide geographic context only.
The dots do not mark code boundaries. ENACOM publishes the code and its head-locality, but not redistributable boundary polygons for all 300 telephone areas. Telephone areas can cross provincial borders, and a code may cover more than one locality. The map therefore does not draw guessed telephone-area boundaries: search for a locality or code, then zoom in to inspect nearby pins.
