Where is telephone country code 54?

Answer 1

Telephone country code +54 (dialed as 00 54 from many places) is Argentina. All numbers have 10 more digits after the country code. Note that you must omit the trunk prefix 0 from the beginning of the Argentinian number when calling internationally. For example, Buenos Aires' area code 011 becomes +54 11.

Mobile numbers use the same geographic area codes as landlines. Within Argentina, the prefix 15 must be added between the area code and the subscriber number when calling to a mobile phone. However, this prefix is not added when dialing internationally.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

Answer 2

Telephone country codes never begin with zero.

Country code +54, dialed as 00 54 from many places, is Argentina.

Country code +4, dialed as 005 4 from many places, is an incomplete code somewhere in Europe. You need one or two more digits to specify the country. For example, +49 is Germany.

To avoid confusion, it is best to write an international telephone number in correct international format, beginning with the plus symbol and the correct telephone country code (e.g., +54 or +49), omitting any dialing prefix.
