If your library card number and PIN don't seem to work, here are some common causes:
- Make sure you type the card number and PIN without spaces. Your card number can be found under the barcode on the back of your card.
- Your library card number may have expired if you have not used your library card at all in several years. If you replaced your library card with a new card, you previous card number will no longer work.
- Our records may indicate a different PIN. To reset your PIN, visit sonoma.bibliocommons.com/user/forgot - enter your library card number or username, and and a recovery link will be emailed to the email address associated with your account.
- There may be a problem with the library's network—or your own network or device. Try again after a little while.
If you forgot your library card number, please call or visit your local branch. You may also send us your full name, address and year of birth by webform, email, or text message (707) 632-4591 and we can look up that information for you.
