Dialing out

Trunk prefix

Argentine mobiles wear two disguises. At home you dial the trunk zero, the area code, then 15 and the subscriber number. From abroad the 15 disappears and a 9 slips in between +54 and the area code instead: 011 15 1234 5678 becomes +54 9 11 1234 5678. No arithmetic maps one onto the other, so copy the +54 9 form for anything international.

Area codes run 2 to 4 digits (Buenos Aires is 11); domestic mobiles insert 15 after the area code, subscriber numbers fill the rest to ten digits.
