Your membership number is either the barcode number on your library card or the number on the back of your HillingdonFirst card.
Activating your library membership
If using your HillingdonFirst card as your library membership card, it must have been activated at one of our libraries.
If you haven't been an active library user in the last 2 years, you will need to contact your local library to reactivate your membership, providing additional proof of your name and address. You can also email email@example.com to get set up online.
