How long is a VA certificate of eligibility good for?

A VA Certificate of Eligibility (COE) does not have an expiration date; it remains valid as long as the veteran maintains their eligibility status. However, if the veteran has used their entitlement for a VA loan and later pays it off, they can restore their entitlement and obtain a new COE. It's important for veterans to periodically check their eligibility status, especially if they plan to apply for another VA loan in the future.
