Important Information about your Library Card and Account

Your full-access library card is free and allows you to borrow materials from all 26 community libraries of the Contra Costa County Library. In addition, a full-access library card provides access to online resources, free and discounted museum passes, internet access, and more. Applicants must be present to receive a library card. Your Library card is valid for 3 years from the date of issue. Expired cards can be renewed for free in person at any Community Library upon presentation of valid picture ID and proof of current address.

Children under 13 must be able to write or print their names (first name only is acceptable). The signature of the parent or legal guardian is required on applications of children under 13 years of age. Before signing as a parent or legal guardian, please be sure you have reviewed the privacy policy statement. The applicant, parent, or legal guardian must provide picture identification and address verification.

The following picture ID and address verification will be accepted when applying for or renewing a library card:

  • Current California driver’s license or California ID card (temporary driver’s license is not acceptable)

OR any combination of two from this list, including the following:

  • Any government-issued picture ID (military ID, green card, etc.)
  • Student ID card
  • Recent student report card
  • A credible ID issued by a reputable business or organization
  • Imprinted bank check (personal check or payroll check made payable to customer)
  • A piece of first class mail postmarked within the past 30 days
  • Voter registration card
  • Utility bill (print or electronic)
  • Automobile registration
  • A letter from a Social Service Provider stating that the individual receives mail at the provider’s address

If no verification for a permanent address can be shown, an Address Verification Postcard can be sent to the patron’s residence. The postcard can then be returned to the library in person and presented along with photo ID to receive a library card.

You need only one library card.

Contra Costa County Library has contracted with Unique Management Services (UMS) to act as our materials recovery/billing agency to recover identified overdue materials, charges, and fees. Accounts sent to UMS are assessed a $10.00 collection/service fee to cover the cost of doing business with the agency.

After 60 days past due, delinquent accounts with a balance of $50.00 or or more will be referred to UMS.

Those borrowers under 18 years of age will not be contacted directly by the materials recovery service. All correspondence will be directed to the “parent or guardian of…."

When an account is referred to UMS, a $10.00 charge is automatically posted to the account and any account referred to UMS is blocked from checking out additional materials. The account must be resolved and all items returned and/or paid in full before borrowing privileges are re-instated.


The Library will send notifications as follows:

Holds ready for pick-up:

  • WHEN A REQUESTED ITEM IS AVAILABLE FOR PICK-UP: When an item is available at the requested pick up location a hold pick-up notification will be sent by email, phone, text, or U.S. mail. Items will be held for 7 days.

Due date reminder notifications:

  • 2 DAYS BEFORE ITEMS ARE DUE: Courtesy due date reminder notice is sent by text or email.

Overdue notifications are sent as follows:

  • 10 DAYS OVERDUE: Library sends overdue notice by e-mail, phone, or U.S. mail
  • 30 DAYS OVERDUE: Overdue items are now set to Lost. Library sends a bill by U.S. mail for lost item(s). The account is blocked.
  • 60 DAYS OVERDUE: Account balances of 50.00 or more are referred to a materials recovery agency, Unique Management Services (UMS, aka Unique National Collections); and a $10.00 materials recovery fee is added to the library card account to cover that cost. UMS will attempt to contact the cardholder or their parent (if cardholder is a minor), both by phone and U.S. Mail. Accounts will be blocked and remain in collections status until overdue materials are returned and/or outstanding fees and charges are paid in full, and any remaining account delinquencies are otherwise resolved. All inquiries and payments should continue to be directed to Contra Costa County Library.

You will be provided with the due date at the time materials are borrowed. You may also check your due dates and current account status online at, by calling 1-800-984-4636, or visiting your nearest community library. Library Notices are provided as a courtesy. Borrowers are responsible for returning materials on-time.
