How do I activate my Tesco Bank Credit Card?

If you are the primary card holder you can activate your card via the Mobile Banking App, or by calling us on 0345 072 9072* (Minicom 0345 671 0676*). If there are additional card holders on the account then this will also activate their cards.


You will be asked to enter your 16 digit credit card number so please have this with you when you call. If you’ve registered for Online Banking you will also need to enter selected digits from your Security Number.


*This number may be included as part of any inclusive call minutes provided by your phone operator.

I am trying to activate my new credit card but I am currently abroad. My son will do it for me but he is having problems. How can I rectify this? 

Hi @Royc



To activate the card you will need to either give us a call on our international number +44 1268 508 027 (24/7, charges can be reversed by letting the operator know) or download the banking App. I appreciate this may be inconvenient for you if you are abroad, however it needs to be you who activates the card as opposed to your son on your behalf. 




Unfortunately there is no system here for reverse charge calls. Would they call me back if I asked? 

We wouldn't be able to arrange a call-back for you via this channel I'm afraid @Royc, although if you download the banking App you can activate the card on there and this won't cost you to do so :-)

I have received my Tesco credit card how do I activate it pleasewhat does it mean my security number .

@Babygirl62 I've responded to your other post here


How can I activate my Tesco card when I fine do you have to speak to anyone and what information will they ask for please as I find it hard to speak on the done 

Hi @Babygirl62, it's an entirely automated service. As long as you have your 16 digit card number then there will be no issues :)


How long after activating my credit card can I use it? I activated it via the app but just tried to use the card and it was declined.

If the card is activated it should work straight away @Rieley, did you use the contactless functionality? If so, this won't work first time around as you have to use the chip and PIN feature first. 


If it was chip and PIN, can you confirm what message was displayed when the payment was declined?
