You usually get a library card by applying with your local public library (often online), then showing ID and proof of address when you pick it up in person; kids often need a parent or guardian to sign.

Basic steps

  • Find your local library’s website and look for a “Get a library card” or “Join the library” page; most systems explain eligibility, ages, and what documents you need.
  • Fill out an application form online or in person; many big-city libraries let you pre‑register online and then finalize in a branch.
  • Bring a photo ID plus proof of address (like a driver’s license, recent mail, or student ID) to the desk so staff can verify who you are and where you live.

Adults and teens

  • Public libraries typically offer free cards to people who live, work, or go to school in the service area; some also accept people who pay local property taxes.
  • Many systems let adults and teens 13+ apply online for a full or temporary card, then complete verification later in person; some places do not require teens to show ID if they’re verifying an existing online application.

Kids and families

  • Children usually can get cards from a very young age, but a parent or guardian generally must sign the application for younger kids (often under 12–13).
  • Once the card is set up, parents can use it to check out children’s books, join storytimes, and access digital reading apps for their kids.

Digital and online-only cards

  • Many libraries now offer digital cards or “eCards” that you can get entirely online if you’re a resident; these give access to ebooks, audiobooks, and online databases, but sometimes not to physical checkouts.
  • Some systems issue a temporary online card first, then convert it to a full physical card when you later bring ID and proof of address into a branch.

If you don’t live in the area

  • If you live outside the main service area, some libraries still let you get a card, but you might pay an annual fee instead of getting it free.
  • In regions with shared systems (for example, statewide or countywide networks), one card can often be used at multiple partner libraries and in common ebook apps.
