Why do I have to enter my library card number and why is the barcode such a long number?

  • When Ventura County Library purchases databases, ebooks and eaudiobooks, we enter into a license agreement with the vendor regarding who has access to content. These agreements require us to authenticate your library patronage by using the 14-digit barcode found on your library card to gain entry.
  • Library Cards may be obtained at any Ventura County Library location by filling out an application form and presenting it with identification which shows your current street address. (Driver's license is preferred. If you have just moved, a letter or bill with your current address is acceptable. A child may bring in a parent's identification.)
  • Unfortunately, back when barcode cards were created, future applications and usage were unknown. We apologize for the long number!
