International Country Dialling Codes

Country Dialling Codes (also known as international direct dialing (IDD) codes), are required to access international telephone services. The numbers are assigned by the International Telecommunication Union in standard E.164.

To call internationally from the UK, you will need to dial 00 followed by the relevant Country Dialling Code (listed below) of the country that you are calling.

For example, if you are calling someone in the USA with the national telephone number 516 321 1234 a UK caller should dial as follows:- 001 516 321 1234.

Some countries require the caller to omit the leading 0 of the national area code. For example, to call someone in Germany with the national telephone number 089 123456, a UK caller would need to dial +49 89 123456. However, the same does not apply for other countries e.g. Italy.
