Your Clubcard number is a unique number that is used to identify your Clubcard account. It's made up of 18 digits. When signing in to your Clubcard account, you may be asked to enter some digits from this number for security purposes.
Some customers may have more than one Clubcard number linked to their account. For instance, if you have a Tesco credit card, this will have its own Clubcard number.
You can find your Clubcard number on the front of your plastic Clubcard, your key fobs or in the Tesco Grocery & Clubcard app – under ‘Clubcard management’. It's also listed in your Clubcard account online.
If you have a Tesco Bank card, it'll be on the back, underneath your signature.
