How Do You Properly Endorse a Check?
Flip any check over and there’s a blank strip of lines on the back waiting for a signature — a small step that’s easy to rush through, but the way it’s filled in actually changes what can be done with the check next.
The short answer
Endorsing a check means signing the back of it, and the correct way to do so depends on how the check is being deposited or cashed. A standard signature works for an in-person deposit or cash-out, a restrictive endorsement is generally required for mobile deposit, and a check made out to two people may need one or both signatures depending on how the payee names are joined.
The standard endorsement
For a routine in-person deposit or when cashing a check at a teller window, the payee typically just signs their name on the back, matching how it appears on the front of the check as closely as possible. This is sometimes called a blank endorsement, and once it’s signed this way, the check technically becomes payable to whoever is holding it, which is part of why it’s worth signing a check only right before depositing or cashing it rather than in advance.
The restrictive endorsement for mobile deposit
Most banks ask for a restrictive endorsement when a check is being deposited through a mobile banking app, typically the signature plus a line such as “for mobile deposit only” and sometimes the account number. This limits what can be done with the check once it’s endorsed, which matters because a photographed check that’s already been scanned and deposited could otherwise still be usable if the physical paper isn’t destroyed. Banks often specify their exact wording requirement in the app itself, and skipping it is a common reason a mobile check deposit gets rejected or delayed.
When a check is made out to two people
How a check names two payees determines whether one or both signatures are needed:
- Joined by “and.” A check made out to “Jordan Lee and Sam Lee” generally requires both people to endorse it, since the wording implies the funds belong to both jointly.
- Joined by “or.” A check made out to “Jordan Lee or Sam Lee” can typically be endorsed and deposited by either person alone, since the “or” phrasing treats either payee as authorized on their own.
- Ambiguous wording. If it’s unclear which format applies, or the names are simply listed with no connecting word, a bank may default to requiring both signatures to avoid a dispute later.
This distinction is one reason couples or joint bank account holders sometimes run into friction depositing a shared check, since the account being joint doesn’t override how the check itself is worded.
Why the details matter
A check with a missing, illegible, or mismatched endorsement can bounce back at deposit or cause a delay while the bank sorts it out, and a check endorsed too early — before it’s actually being deposited — creates a small window where it could be cashed by someone else if lost. This is different from something like a cashier’s check or money order, which involves its own separate verification steps, but the underlying idea is the same: the signature on the back is what authorizes the transfer, so it’s worth treating carefully.
A practical habit
Waiting to endorse a check until the moment of deposit, using the exact restrictive wording a mobile app requests, and confirming how multiple payees are joined before assuming either signature will do are all small habits that keep an otherwise routine deposit from turning into an unnecessary delay.
