Find out your international phone number so you can receive phone calls and texts from abroad.
If you’d like to receive a phone call from someone in another country, you’ll need to convert your UK phone number into an international phone number. The easiest way to do this is to replace the zero at the start of your phone number with +44.
Your International Phone Number
Enter your UK phone number below to convert it into an international phone number:
Please enter your phone number:
Enter a UK number. For instance, 07123 456 789.
Your international phone number is:
+44 [UK number without leading zero]
Your contacts who are calling from another country will also need to add the relevant international direct dial (IDD) prefix in their country. If you’ve already entered your phone number above, the table below will show the exact phone number your contacts will need to dial:
Alternatively, if your contacts abroad are calling you from a GSM mobile phone, they can input the +44 prefix directly into their handset (to get the plus sign, you’ll need to long-press on the zero button in your mobile phone’s dialler).
If you’re using a UK-based SIM card in the UK or Europe, it will always be free for you to receive an incoming phone call (to be clear, there are no additional charges for receiving an incoming international phone call).
If you’re travelling outside of Europe, the normal roaming charges might apply for receiving an incoming phone call.
Frequently Asked Questions
If you’re travelling abroad to another country and roaming on your UK-based SIM card, your international phone number will still remain the same. The +44 at the beginning of your international phone number refers to the fact you have a UK-based number (you don’t necessarily need to be physically inside the UK).
If you’re using a different SIM card when travelling abroad, you may have a local phone number in the country where you purchased your SIM card. In this case, you’ll also have a new international phone number.

When you convert a UK phone number into an international phone number, you should remove the zero at the start and replace it with +44. A common mistake is to leave the zero in place – this is incorrect and will lead to the phone call failing to connect.
UK phone numbers are sometimes written with the leading zero in brackets: for instance, +44 (0) 7123 456 789. If you see a phone number written in this format, you should remove the zero that’s in brackets to get your international phone number.
Your contacts who are calling you from abroad will need to pay their phone company for an international phone call to the UK.
Typically, a different rate is charged for calls going to a UK landline and to a UK mobile. UK landline phone numbers begin with either +44 1 or +44 2, whereas UK mobile phone numbers begin with +44 7. The interactive tool above will tell you about the type of phone number being called.

Visiting The UK
If you’re visiting the UK on a short-term trip, it may possibly make sense to get a UK-based SIM card. If you do this, you’ll be assigned a new UK-based phone number. Any contacts living outside the UK will need to call you on your international phone number (use the form above to find out your international number).
