Interaction with national area codes

 

 

 

 

 

Some countries such as Germany and the United Kingdom require the caller to omit the leading “0” of the national area code when used internationally. It’s because the leading zero is an indicator that a national prefix follows, rather than simply a local number. This is similar to the use of a trunk code  in countries like the United States, which uses a leading “1” to indicate that a national area code follows.

 

 

 

 

 

For international dialing, the national prefix is always used, and so the trunk code is not needed. For example, to call a subscriber in Germany with the national telephone number 089 (Munich) 987 65 43, somebody outside of Germany would have to dial +49 89 987 65 43, where the “+” stands for the international prefix.
