In Argentina, area codes are two, three, or four digits long (after the initial zero). Local customer numbers are six to eight figures long. The total number of digits is ten, for example, phone number (11) 1234-5678 for Buenos Aires is made up of a 2-digit area code number and an 8-digit subscriber's number, while (383) 123-4567 would be an example of a Catamarca number.
Local landline phone numbers in Argentina can have 6, 7 or 8 digits, depending on where they are located:
Local numbers usually begin with a 4, although in recent times numbers having 2, 3, 5, 6, or even 7 as the first digit are not uncommon.
Thus, for example to call a local number within Buenos Aires, one should dial 1234-5678; within Mar del Plata, 123-4567 and within Villa Carlos Paz, 12-3456. For mobile phone dialing, see the corresponding section below.
In March 2011, the CNC (National Communications Commission, the telecommunications regulatory agency in Argentina) announced changes to be carried out in 21 local areas throughout the country. The reason being the soaring demand in mobile lines causing lines to be nearly depleted in many areas. The changes will take place in three stages, starting in November 2011 with the final cities having their numbering plan changed in April 2012. Users in these areas will have an extra 4 added in front of their subscriber's numbers as well as having the area code shortened. Thus, they will go from a (xxxx) xx-xxxx format to a more resourceful (xxx) xxx-xxxx. On 1 April, seven cities had their numbering changed as described above, thus completing the update process.
To dial a long-distance number in Argentina (whether landline or mobile), the area code must be dialed before the subscriber's number.
As explained before, area codes can have 2, 3 or 4 digits and must be dialed before the local subscriber's phone number.
In addition, to place a domestic long distance call, trunk code 0 must be dialed as well.
Thus, for example, in order to call a landline phone in Ushuaia from Salta, one should dial: 0 + 2901 + xx-xxxx, where 0 is the trunk code, 2901 is the Ushuaia area code, and xx-xxxx is the local phone number.
The same rule applies to mobile phone numbers, with the addition of the mobile prefix 15 right in front of the local subscriber's number. Using the same example above, to reach a Ushuaia mobile from Córdoba, one should dial: 0 + 2901 + 15 + xx-xxxx
Although trunk code 0 is not part of the long distance area code, it is normally represented as if it were part of the long distance prefix. Thus, when given a long distance number already including a 0 in front of it, no additional 0 is to be added in order to call domestically.
