How to Make an International Phone Call

1. Dial the International Access Code (IAC)for the country you are calling from. 
   
   For example, the IDD to call from the United States to another country is 011.  In the United Kingdom and in many other countries, the IDD is 00.  Other countries have different numbers, or may offer more than one depending on the carrier and type of service.  Make sure you have the correct IDD for the country you are calling from.  These will be the first numbers dialed, as shown below.
   
   NDD Prefix (National Direct Dialing)
   
   The NDD prefix is the access code used to make a call within that country from one city to another (when calling another city in the same vicinity, this may not be necessary).  The NDD is followed by the city/area code for the place you are calling (city/area codes, where applicable, can be viewed by following the link from the country name on the table below).  Phone numbers are often written in this format: +44-(0)1224-XXXX-XXXX.  This expresses the numbers used for both international and national long-distance calls.  In the example, +44 indicates the country code, while (0) indicates the NDD.  When dialing from outside the country, the NDD would not be used after dialing the country code; when dialing from within that country, the NDD would be used, but the country code would not. 



2. Dial the country code - the digits immediately after the + sign.  See below for a list of codes.



3. Dial the number - omitting the number, usually a zero, in brackets (if there is one).
