What is Oyster?

Oyster card

With an Oyster card you can:

Find out where to get Oyster cards.

Reusable and flexible

You can top up with pay as you go credit or renew your Travelcard or Bus & Tram Pass on the same Oyster card when you need to.

If you keep both pay as you go credit and a Travelcard or Bus & Tram Pass on your Oyster card at the same time, it works out which one to use to make sure you never pay more than you need.

When you get a new Oyster card, you'll need to pay a £5 deposit. If you decide you don't need it anymore, return your Oyster card to us and we'll refund your deposit.

Sign up for Oyster online

If you sign up for an Oyster online account, you can see what's on your Oyster card, see your journey history and apply for refunds. Any Oyster cards that you add to your account will automatically be protected against loss or theft. 

Oyster cards that you add to your online account will automatically be protected if lost or stolen, so that no one can use it once you've reported the loss or theft. You may also be eligible for a refund or replacement of  any remaining pay as you go credit or the days left on your Travelcard or Bus & Tram Pass.

Registering your Oyster card

You need to register your Oyster card if you want to add Travelcards and Bus & Tram Passes valid for longer than a month to it.

To register, fill in an Oyster Card registration form and take it with you to any of the following places:

  • Your local Oyster Ticket Stop
  • A Tube, London Overground or selected National Rail ticket office
  • A Travel Information Centre

If you've protected your card online (by adding it to your online account), you'll still need to register it at a Tube station to buy Travelcards or Bus & Tram Passes valid for longer than a month.

Simply sign in to your Oyster online account, choose the Oyster card you wish to register (if you have more than one card) and then click on 'Card overview'. Here you will find an option to print out a PDF form as proof of ownership. Print out the registration request form and take it to any Tube station ticket office and a member of staff will register your Oyster card.

Visitor Oyster cards can't be registered or protected.

No longer need your Oyster card?

Unused pay as you go credit stays on your Oyster card until you want to use it. If you don't need your Oyster card anymore, you can return it for a refund of any remaining pay as you go and your deposit. Find out more about Oyster refunds.

Lending your Oyster card to others

If your Oyster card only has adult rate pay as you go credit on it, you can lend it to someone else, even if the card is registered in your name.

An Oyster card can't be used by anyone other than the registered user if it has one of the following on it:

  • Travelcard or Bus & Tram Pass season ticket
  • Jobcentre Plus Travel Discount
  • Bus & Tram discount
  • National Railcard discount
