Hi there!

This is one of our most-viewed guides! If you landed here in search of info on what your mobile number is, would you mind letting us know some details on why you're searching for this, in our feedback topic here? We'd like to gather some insights to understand the issue better. Thanks a lot in advance!

Someone asks you for your number, the mind goes blank. Who dials their own number, right?

Well, fear not: There are 5 fairly simple methods, and one not-so-direct one, to find out what your own phone number is...  Well, OK, ease is relative, but take a look below and see which suits you best!

 


 

1) If you own a PAYG phone, the phone number is printed on the PAYG SIM pack, as shown (partially redacted) below:

2) If you don't have the SIM pack but do have credit, you can call a friend or associate and the number will show up on the recipient's phone:

3) If you don't have your SIM pack OR any credit, O2 Live Chat can get the mobile number, when you ask, but you will need to quote your SIM serial number. This requires you to open the SIM carrier on your phone and carefully remove the SIM card.

  1. The location of the SIM number on a standard SIM card (and on the card the SIM came with) is shown here:
    image8.jpg
  2. The SIM number location on a Micro or Nano sim is shown below:
    image6.png
  3. The link to “O2 Live Chat” can be found here: https://www.o2.co.uk/contactus

4) Text the word NUMBER to 2020 – it's free to send this text and O2 will reply with your phone number, as shown here:
image4.jpg

 


 

5) There should be an option to see My number in your phone’s menus.

 

  1. On an Android-based phone, you can see if your number is listed in
    Settings > About phone > Status > SIM Status > My phone number > 
    image5.jpg
    However: Dependent on the software version, it may or may not show a mobile number.

    Also please note this menu path may vary depending on the Android phone, and the version of Android, in question -  the menus all differ slightly.

  2. If you’re an iPhone owner, navigate to Settings > Phone and My Number will be the first field on the list:
    image1.jpg

 


 

6) It is listed at the very top of the MyO2 app opening screen:

And lastly, if anyone tells you that you can get your telephone number by looking up your phone’s IMEI number (often listed on the package your phone came in), don’t believe them - it’s not impossible, but requires access to telco’s equipment at a level that normally neither you nor the telco have.

Great little guide @pgn

Though I can remember mine. Had it 10 years now

I checked my husbands for him today, it can also be found in Settings >>> About phone... on his Samsung S7edge  (I didn't need to go into Status or Sim status) wink

Thank you, @Cleoriff - and I think your hubby's Samsung S7edge is captured under the caveat "please note this menu path may vary depending on the Android phonethumbsup

Easiest way to find out is by sigining into your account for me although I had the same number for years now. I haven't used PAYG for a few years now so got out of the habit although generally you used to find it in a section called My Number or About telephone as said. Most VMNP have the number displayed there whereas I noticed o2 contracts don't display the number at all for "security" reasons.

Great work @pgn, thanks for taking the time to write this up! slight_smile It might sound surprising but we actually have many people searching on the community how to find their own mobile number, so this will surely be a helpful resource for many.

 

Thanks!

And this Guide has made it onto the Community Carousel, yaay!

 

I think that deserves a blast of this (the extended version!):

 

Thanks everyone for the comments that I could incorporate, and for @anticpated, yes, whilst not on the bill, your number is (if you've remembered it and registered on O2's website) there in front of you when you log in.  I guess options (3) and (6) both need you to have done that, so that's a good suggestion too - the unwritten (7)? wink

You would have to call customer service.Why not just order a free sim online and the mobile number will be on the packaging.

I didn't know that you can text NUMBER to 2020 and it will text you back with your number. You learn something new everyday! 😄

Seen this question asked a lot as I've also asked the question, with all the unusual solutions which don't work on new payasyougo Sims.

 

https://myo2payg.o2.co.uk

 

Turn on mobile data & go to the above in the default browser.  It'll load up to myo2 with your number which will also be present in the address bar although no data it'll still load this part of o2's site

Once the sleeve the SIM is sent to you in is lost or discarded, without credit you cannot call another number, fair point. Interesting.

Good tip about the mobile data, must try it on one of the PAYG phones in the house later, @Onetwo - thank you for the tip.

@Martin-O2  @Breanna - this tip may need to be added to the Guide above, with a screenshot when I get one 👍

I always keep spare Sims but can't always keep packaging.  Had used the mobile site above however forgot what it was as I kept trying to go to my O2 which couldn't detect the number. 

 

Eventually somehow I got to that page and it was the same I used some year's ago so thought certainly need to log it as I've not seen it on O2 or other guides when doing generic searching.

 

The difficulty with new O2 Sims is one can't send free texts for balance, number etc, as the SIM isn't activated as such however can still receive calls, texts.  I also Thought  requesting a pac would text the number to me but with new Sims you can't request PAC via text, it must be done on myo2.

Q: Apple Watch device phone number: how do you find this? 

A: Nowhere – you have to waste your valuable time phoning O2 CS and have them tell it to you

Why does that not surprise me. 🙄

Hello, I’m from the future, as of 13 February 2024, when I text number to 2020 on an O2 pay as you go simcard, the smartphone simply says it can’t send the text message with error message “can’t send message with O2 - error 0”, and reports unknown number under the Android sim manager for O2, whereas it easily reports the number for every other major UK PAYG telecom provider such as EE, 3, and Vodafone!

@OFromTheFuture2 - last used in jul-23, but still working just now:

Try disabling dial-smart-assist on your phone, or enable RCS fully, or try a different messaging app. Type the number anew into your messaging app rather than using the stored number too. Good luck!

@OFromTheFuture2 

Have you topped up your sim Guide How to Top Up (PAYG) ?

You need an active bundle to send the text.

Also, O2 don't push numbers to sim cards like the other networks so your number won't show in Android settings, on O2 it only works for iPhones.
