How to Get a Library Card in Any U.S. State

By the Public-Libraries.com Editorial Team · Updated September 13, 2026

What you need to get a library card

Almost anyone who lives, works, attends school, or owns property in a library’s service area can get a free card. To sign up you’ll usually need two things: proof of identity (a photo ID such as a driver’s license or state ID) and proof of address (the ID itself, a piece of mail, a lease, or a utility bill). Requirements are set by each library system, so a nearby branch is the final word — but this combination works almost everywhere.

How to get a library card, step by step

1. Find your library. Look up the public library that serves your town or county (you can browse by state and city in our library directory).
2. Apply online through the library’s website or in person at any branch.
3. Verify your identity and address.
4. Get your card — a physical card at the desk, or a card number instantly online.
5. Start borrowing books, e-books, and more, in person and through apps like Libby.

Get a digital library card in minutes

Many library systems now issue an instant digital card. You register on the library’s website (or right inside the Libby app), confirm you live in the service area, and immediately get a card number you can use to borrow e-books and audiobooks and to sign in to your state’s online resources. A physical card can follow later if you want one for in-branch use.

How to get a library card for a child

Children can have their own library card, and at most U.S. public libraries there is no minimum age. A library will issue a card to a baby or toddler as long as a parent or legal guardian signs the application. The adult is usually asked to show their own ID or proof of address and is responsible for whatever the child borrows. A few systems set a minimum age only for signing up online on your own — older children can self-register while younger ones register in person with a parent — so check your library’s page.

Three real examples show the pattern. The New York Public Library issues cards to children ages 0–12 once a parent or guardian completes and signs the application, and lets the parent choose whether the child can borrow all materials or only juvenile items. The Los Angeles Public Library asks for no ID at all from anyone under 18 — a parent or adult sponsor’s signature stands in for it. The Chicago Public Library issues a youth card to children under 14 when a parent or “guarantor” signs and shows one ID with a Chicago address.

Two things make a child’s card easier than it used to be. First, many large systems are now fine-free — Chicago dropped daily overdue fines in 2019, so a late picture book no longer builds up charges (you still replace a lost item). Second, some cities give students a card automatically through school programs: every Los Angeles Unified K–12 student is assigned a fine-free Student Success Card, and New York City’s MyLibraryNYC links a student’s school and public-library accounts. These are city-specific programs, not available everywhere, so ask your local library or school.

Is a library card free? What it can cost

For residents, a public library card is free — that’s the whole point of a public library. Some systems sell an optional non-resident card (an annual fee) to people who live outside the service area but want borrowing privileges. Late fees are also increasingly a thing of the past: many U.S. libraries have gone fine-free for overdue items.

Lost card, or forgot your number?

Your library card number is the barcode number printed on the card, and it also shows in your online library account and in apps like Libby — useful when you’re signing in to a database or borrowing an e-book and don’t have the card in hand. If you can’t find it, your branch can look it up for you with a photo ID.

If your card is lost or stolen, tell the library promptly so they can deactivate it — you’re responsible for anything checked out until you report it — then ask for a replacement. The fee is small and varies by system: the New York Public Library charges $1, the Los Angeles County Library charges $3, and some libraries replace it for free. See our guide to replacing a lost library card for the steps.

One card, many libraries: reciprocity and consortia

In much of the country your single card reaches far beyond one building. Regional consortia let you borrow across dozens of libraries with one card — for example the Jefferson County Library Cooperative around Birmingham, the Allegheny County Library Association around Pittsburgh, and Ocean State Libraries across Rhode Island. Ask your library whether it belongs to a shared network.

What your library card unlocks in every state

Beyond books, your free card signs you in to your state’s free online library — research databases, magazines and newspapers, learning tools, and e-books. Here’s the statewide resource in each state; for the full breakdown see our guide to free online library resources by state.
