How to Format International Telephone Numbers for Dialing a UK Number
The most important part to remember is to add the international country code. UK number always starts with the digits ’07’, for instance ‘079xx xxx456’. If you would not add an international country code, the computer might interpret that phone number otherwise. The country code for Russia is ‘+7’, and Russian mobile phone numbers start with ‘+79’, so ‘+79xx xxx456’ might be a Russian mobile phone as well.
Therefore, you should add ‘+44’ UK’s country code to make the number unambiguous; ‘+44 79xx xxx456’ will always lead to a mobile phone in the UK.
It might be clever to format numbers using the E.164 recommendation. An international E.164 number is designed to include all of the necessary information to successfully route a call or SMS message to an individual subscriber on a nation’s public telephone network.
Here’s how the E.164 numbering plan works:
- A telephone number can have a maximum of 15 digits
- The first part of the telephone number is the country code (one to three digits)
- The second part is the national destination code (NDC)
- The last part is the subscriber number (SN)
- The NDC and SN together are collectively called the national (significant) number
To use the previous example:
- Country code: +44
- National destination code: 7911
- Subscriber number: xx456
- In total: +447911xxx456
Two important things to note: First of all, in the international E.164 notation a leading ‘0’ is removed. The UK mobile phone number ‘07911 xxx456’ in international format is ‘+44 7911 xxx 456’, so without the first zero. Secondly in the E.164 notation all spaces, dashes [‘-‘] and parentheses [ ‘(‘ and ‘)’] are removed, besides the leading ‘+’ all characters should be numeric.

A great way to check whether a phone number is correct or how it should look in E.164 formatting is using the Phone Number Parser. That is part of a piece of software that Google uses to check phone number formatting in Android phones.
