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.

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

Travelling Abroad

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.

For more information and for useful tips about using your mobile phone abroad, please see our in-depth guide to this topic.

Leading Zero

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.

Call Costs

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.

If you’d like to call internationally from the UK, see our guide to the best mobile phone networks for international calling.

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).

    +63**** this number appeared on my phone don’t no what code or country it’s from can you help thanks

  • Ken, this passage of knowledge led more questions to my mind. I wonder if I can transfer a foreign phone number to a UK SIM card via foreign PAK code?

    • Hi Shan,
      Sadly not! Phone numbers can only be transferred between two UK mobile networks, and this only works with UK based mobile numbers (+44 7).

  • Hi ken,

    I’m from Australia but applying for jobs in the U.K, I’m just wondering how best I should put my phone number down so I can be contacted

    • Hi Regan,
      Are you using an Australian phone number? If so, I’d recommend providing your phone number with the +61 international prefix at the start. You could also write it with 0061 at the start if you prefer.

    • Hi Sally,
      Thanks for your comment. Your Caller ID will continue to show the phone number associated with the SIM card you’re calling from. Therefore, if you’re using an Irish SIM card in the UK, it will still show up as an Irish phone number to anyone you call.
      Hope this helps,

  • When go abroad is using the same number for whattsapp but if ordanary text does it comeup different and don’t come up plus 44

    • Hi Caroline,
      If you’re using regular SMS, it will come up with the phone number of the SIM card (so your normal +44 number if you’re using your normal UK phone number).
      Hope this helps,

    • Hi there,
      Sadly, it isn’t possible to have a UK phone number on a South African SIM card. However, there might be some voice-over-IP providers that will give you a UK-based phone number, accessible through an app, at a small monthly cost.

    Hi Ken,

    I want to use my U.K. number but it seems that it is no longer working. I was living in the U.K. for some time but came back home to Kenya. My U.K. number cannot receive any messages and the WhatsApp says that my number is no longer registered. What should I do?

    • Hi Sharon,
      Thanks for your comment. I’m sorry to hear that your UK phone number is no longer working – could it be due to Pay As You Go inactivity? Either way, the best thing to do will be to contact your mobile network operator so they can take a look into it for you, and restore the service if applicable.

    • Hi John,
      Do you have a Nigerian SIM card or a UK SIM card? If it’s a Nigerian SIM card, you’ll need to use +234. If it’s a UK SIM card, you’ll need to use the +44 prefix.
      Hope this helps,

    • Hi Okwara,
      Which mobile network are you on? I don’t think there’s a standardised way to find out your phone number, as the instructions may differ depending on your network. Alternatively, you can often find your phone number through the Settings menu in your phone.

  • Hi Ken
    My wife & I will both be taking our UK mobiles to Canada next month.
    I already have her number in the format +44 1234 56789, but when in Canada will I need to add 011 to call her?

    • Hi Huw,
      Thanks for your comment. No, there shouldn’t be any need to add 011 to the start. As long as the phone number is stored in +44 format, it will automatically be recognised as a UK number wherever you are in the world 🙂

    • Hi Frederick,
      Thanks for your comment. You’ll need to prefix your American phone number with +1 (or 001).
      Hope this helps,

  • Hello.
    I have a friend who uses a mobile with Ghana prefix and number.
    Is he ringing me from. Ghana or could he be ringing me from UK?
    Thank you.

    • Hi Jean,
      Thanks for your comment. Unfortunately, it’s impossible to know from the phone number alone. It simply means he is using a Ghana-based mobile phone SIM card (that could either be from inside Ghana or it could be outside in another country using international roaming).

    • It is unlikely they are calling you from Ghana as they really do not have money for calling abroad.They are clever at buying different prefixes too.

  • I’m trying to complete a form for a US website and it won’t except my mobile number in any of the suggested formats?

    • Hi Candy,
      If you need to enter your phone number on a form, I’d normally go for the +44 format. However, in this case, it sounds like the website might not be set up to accept phone numbers from outside the US 🙁

    • Hi Isaac,
      On most mobile phones, you can long press the 0 key to get a +. Alternatively, you can dial 00 in place of the + on a UK handset.
      Hope this helps,

  • Hi I am going to Portugal and will be using my UK mobile and sim. I want to know if I ring someone in the UK how will the caller ID be displayed? My normal number starting with a 0 or something else?

    • Hi Terry,
      Your normal UK phone number will show up on other people’s screen, and if you’re in their address book, it’ll be recognised as you too.
      Hope this helps,

  • I will be travelling to Italy and purchased a sim card which allows to be used across Europe. The sim card is in UK number. If my family member (not from Europe or US) would like to call me, do they add UK country code +44 or +39 which is Italy’s country code. My mobile starts with 077.
    While at it, I tried using the table you have provided and entered my contact number. It shows +44 is required to be added. So I would like to confirm.

    • Hi Mau,
      Thanks for your comment. As you have a UK-based SIM card, they will need to dial the UK country prefix of +44. The country code always refers to where your SIM card is based, rather than which country you’re physically located in at that time.
      Hope this helps!

  • Hi I will be in the USA for 2 weeks on holiday from the UK, my family who live in USA want to ring my mobile to keep in contact, what number should they dial from their US mobile?

    • Hi Karen,
      Are you using your normal UK phone number? If so, it’ll be your normal UK phone number with the 0 at the start replaced by +44 (or 011 44 if they’re calling from a landline).
      Hope this helps,

  • So confused ….
    Ok hope this sounds straightforward .

    I am travelling to Spain Andalucia for 2 weeks , and my son may want to call me from a uk landline / payphone as that’s his only contact . At present I have normal uk number that links to my mobile number , making calls cheaper for him than ringing my actual uk mobile number .
    What codes does he need to dial to get me through each number . Mobile and the land line number linking to my mobile .
    Mobile starts 0777 and landline area code 01432 ?

    Appreciate help Thanks

    • Hi Ros,
      Many thanks for your comment. I believe he just needs to dial the normal UK phone number, and it should connect as usual to your mobile phone, even though you’re in Spain.
      Hope this helps,

      • Thank you Ken for your reply which I found to be correct , when my son called me .
        Really appreciate your help


  • Hi I’m in the uk and someone wants to call me from America will it cost me for them to call me or will it only charge them

    • Hi Matt,
      Thanks for your comment. There are no fees for you to receive the phone call from America, assuming of course, you’re currently in the UK. The fees for international calling will incurred by your friend in the US who is calling you.
      Hope this helps,

  • Hi Ken
    Do you know why t-mobile, here in London, England, have changed all the call numbers and text numbers on my Nokia phone from first digit 0 to +44 and does that mean that they’re routing my calls abroad and charging me inflated fees? Or what are they up to? Or possibly is it some kind of hacking? Or just a fault? I’d assume that it’s t-mobile or hackers trying to rip me off as otherwise what would be the motivation for a change like that. Or what? Thanks if you can help,

    • Hi Dave,
      Many thanks for your message. I can assure you this is definitely not due to hackers or anything like that! Lots of mobile phones actually store phone numbers in your address book with the +44 prefix. The reason for that is so it will continue to work when you go abroad (so even if you were using a SIM card from another country, the +44 prefix ensures it will always be treated as a UK phone number).
      Rest assured, you won’t be charged for an international call if you’re inside the UK (you’ll pay the exact same regardless of whether you dial with +44 or 0 at the start of the number).
      Hope this helps,

    Hi Ken

    My mum made a call to Bangladesh through her mobile phone on vodaphone however it was only 00:00 long how much should she be charged for that

    Thank You in advance for your response

  • MR DEREK LOGAN said:

    Hi Ken
    A quick question; I’m trying to contact an UK car hire company from my mobile here in the UK. The only number they appear to be giving out is their International one starting 0044. Will I be charged at International rates for dialling this number? Thanks and thanks for a very informative web site.

    • Hi Derek,
      Thanks for your comment! If you’re calling the phone number from inside the UK, you’ll only be charged the normal UK rate (so absolutely fine to dial this with the 0044 prefix). If you’d like a bit of extra reassurance, you can replace the 0044 with a 0. This should give you a UK phone number in the normal format.
      Hope this helps,

  • Hi,
    I have to give a transport company my mobile contact number but not sure what prefix they need.
    They will be in Croatia, I will be in Croatia but I have an Australian mobile phone. Do I tell them +61 4……….?


  • Thanks for the article! To confirm, if I visited the US with my UK mobile (roaming), friends in the US would have to call 001447********* even while I was there in their country?

    • Hi Steve,
      That’s right. Though I think the international calling prefix is 011 in the US so they would dial 011447*********. Alternatively, they could long press the zero button on their phone to get a plus sign and they could dial +4477*********.
      Hope this helps,

  • I am trying to book a flight but it wont accept my phone number which is 01946 xxxxxx. I have tried +44 1946 xxxxxx but it doesn’t work.

    • Hi Nancy,
      Thanks for your comment. Some websites won’t allow you to input a plus sign in the phone number field. You can normally omit this without any problems (e.g. just enter your phone number as 441946xxxxxx).
      Hope this helps,

    • Hi Jessica,
      The international dialling code for Australia is +61. When giving your phone number to someone who lives outside of Australia, you should remove the leading 0 and replace it with +61. For instance, 0455 555 555 becomes +61 455 555 555.
      Hope this helps!

  • Ooh, neato. Thanks for this information. I'm not from the UK, but I'm fairly sure of Australia's internation prefix thing, so this has been helpful.
