Safe-deposit boxes

Does Illinois auction unclaimed safe-deposit-box contents?

Yes. Illinois held or listed a state sale in 2025–26. The Treasurer's sale runs online on HiBid through Lincoln Auction. In 2026: 15% buyer's premium, pickup only at the Treasurer's office in Springfield (the auction company doesn't ship), and first-time bidders must submit a government ID.

Not yet verified: How often Illinois holds the sale isn't stated on the auction page.

After a sale

If the box was already sold, can I still claim the money?

The Illinois pages we read don't say what happens to the money after a sale. Ask Illinois State Treasurer directly; its contact details are on the official site ↗.

How to check

How do I check Illinois for free?

1. Open Illinois's official search: icash.illinoistreasurer.gov ↗. Check that the address is this one before you type anything in.
2. Search your name, any past or maiden names, and any business you ran. If a relative has died, search their name too: heirs can often claim. Ask the state office what proof it needs.
3. If you've lived or worked in other states, search those too. MissingMoney.com ↗, NAUPA's free site, searches most states at once and links back to each state's official claim page.
4. File the claim on the official site and send the proof it asks for, such as ID. Each state sets its own rules.

Finders

Do I need to pay someone to claim it?

No. NAUPA, the national association of state unclaimed property administrators, says there's no fee to search for and claim your property if you use your state's official program. Paid finders are legal in most cases but never required. Some states cap their fees and many require them to register, so check with the state office before you sign a finder's contract. NAUPA ↗
