Find your membership number in one of these places:

  • Below the bar code on the pdf pass attached to your membership confirmation email (if you purchased online)
  • If you have printed a membership card, look above your name.
  • If you have a digital membership card, look below the QR code or at the top of the card details.
  • Below your address on a renewal form.
  • Your membership number will be 12 digits long and start with 501.

Search with the Last Name of the Primary Member. If you use the last name of an additional cardholder, the system will not be able to find your membership.

If you cannot find your membership number, our staff is happy to help! Email or call us at 510-632-9525 x160. Please include your full name and address in your message.

To prevent fraud, our online renewal system will not allow you to change the name of an existing cardholder. If you would like to remove or replace a cardholder name, please contact us by phone, email, or in person at the zoo. If you are upgrading to a higher membership level, you will be able to name additional cardholders.
