How Long Are Uncashed Checks Good for?

Personal checks

With the personal check, if the check hasn't been cashed after 180 days or six months, it will be considered invalid.

Do checks expire if not cashed?

Personal, business, and payroll checks are good for 6 months (180 days). Some businesses have “void after 90 days” pre-printed on their checks. Most banks will honor those checks for up to 180 days and the pre-printed language is meant to encourage people to deposit or cash a check sooner than later.

What is the oldest a check can be and still be cashed?

Banks don't have to accept checks that are more than 6 months (180 days) old. That's according to the Uniform Commercial Code (UCC), a set of laws governing commercial exchanges, including checks.
