How to check your Vodafone SIM card phone number

The quickest way to find your Vodafone SIM card phone number is to dial *#100# from the handset the SIM is inserted in. If that returns nothing useful, try *#101# as a fallback. Both are USSD codes that prompt the network to display the number linked to your SIM.

How do you dial the USSD code to get your Vodafone number?

Insert your Vodafone SIM into a compatible phone, open the standard dialler (the same screen you use to call someone), and type *#100# then press the call button. The number should appear on screen within a second or two. No call is actually made and nothing is charged.

If the screen shows nothing, or shows a blank result, dial *#101# the same way. According to a JustAnswer smartphone expert, both codes can display the phone number on a Vodafone UK Pay As You Go SIM, and trying the second code is the sensible next step if the first one fails.

What if the phone shows "unknown" instead of a number?

This happens. It means the number is not stored on the SIM card itself, which is more common than people expect, particularly with newer SIMs where the number lives on Vodafone's network records rather than on the card. The USSD code can only surface what the network sends back, so if the network does not return a number, the phone has nothing to display.

A few things to try at that point:

• Ask someone to call or text you, then check the incoming caller ID on their phone.
• Log in to My Vodafone at vodafone.co.uk, where your number appears under account details.
• Call Vodafone customer service on 191 free from a Vodafone SIM, and the adviser can confirm the number on the account.

Does this work on Android phones?

Yes. The USSD method works on Android handsets running any reasonably recent version of Android. A YouTube tutorial by the channel vijay raee walking through exactly this process has clocked up 34,000 views, which gives a sense of how many people run into this question. The steps are the same regardless of whether you have a Samsung, a Motorola, or any other Android device: open the phone dialler, type the code, press call.

The codes also work on basic feature phones, since USSD is a network-level function and does not depend on a smartphone operating system.

Is the USSD code the same as the SIM serial number?

No, these are two different things. The number returned by *#100# or *#101# is your mobile phone number, the one people dial to reach you. The SIM serial number (sometimes called the ICCID) is a 19 or 20-digit number printed physically on the SIM card or its plastic carrier. You would need the ICCID when activating a new SIM or porting a number, but it is not the same as your phone number and the USSD codes do not display it.

A quick reference

If neither code works and you cannot access My Vodafone online, calling 191 from the SIM in question remains the most direct route to getting the number confirmed.

insert the SIM into a compatible phone and dial *#100# or *#101# to display the number
