If you wish to register for Decathlon Loyalty program, you can do it either online or while shopping at any of your local Decathlon stores (please see the link for all Decathlon UK stores contact and address information --> http://www.decathlon.co.uk/decathlon-stores.html).
To register online, please visit the link https://www.decathlon.co.uk/en/newcustomer#nomPage=creationCompte1 which will ask you to create an account with us first. Once you have an account, your Loyalty Card will be automatically generated for you and you will be able to see your Loyalty Card number while in your account, personal information section (should be next to your name).
Please note that if you create your Loyalty Card online, physical card will not be sent to you by post but all purchases done online will be automatically recorded. In order to have physical card we would recommend to visit your Local Decathlon branch and you will be able to print card free of charge in the store (you will have an option for different designs as well and can print more than few copies if needed).
I hope this information helps and if you have any more questions, feel free to ask me.
