How to endorse (sign) a check

When someone pays you with a paper check, you can't just walk it into a store and spend it. First you have to 'endorse' it — a fancy word that simply means signing the back to prove you're the person it was written to and that you're okay with it being paid out. It takes about ten seconds once you know where to sign. This guide walks through it.

Where the endorsement goes

Flip the check over. On the back, at one end, you'll see a short section with a few printed lines and often the words 'Endorse Here' and a warning like 'Do not write, stamp, or sign below this line.' That little box is the only place you write. The blank space below it is reserved for the bank. Keep everything you write inside that endorsement area.

The three kinds of endorsement

There isn't just one way to sign a check. Which one you use depends on what you want to happen to the money. All three are easy.

1. Blank endorsement — just your signature

You simply sign your name on the endorsement line, exactly as it appears on the front. That's it. A blank endorsement makes the check cashable by whoever holds it — which is convenient but risky. If you drop it or it's stolen after you've signed, someone else could potentially cash it. So only use a blank endorsement at the very last moment: standing at the teller window or right as you deposit it, not on your kitchen table the night before.

2. Restrictive endorsement — 'For deposit only'

This is the safest option and the one most people should default to. You write 'For deposit only' (some add their account number) and then sign your name underneath. This locks the check so it can only be deposited into your account — not cashed by a stranger. If you're depositing with your phone's mobile-deposit feature, your bank usually requires you to write 'For mobile deposit only' or check a box; follow whatever wording the app tells you.

3. Special endorsement — signing it over to someone else

Occasionally you want to hand your check to another person and let them cash it. You write 'Pay to the order of [their name]' and then sign your own name below. Now they can deposit it. Be warned: many banks are reluctant to accept these 'third-party checks' because they're a common fraud vector, so call ahead before relying on this method.

Common beginner questions

• Which name do I sign? The one on the front. If the check says 'Pay to Robert Lee' but everyone calls you Bob, sign 'Robert Lee.'
• The check is written to two people — do we both sign? If it says 'Alex AND Jordan,' both of you must endorse. If it says 'Alex OR Jordan,' either one can.
• What pen? Blue or black ink. Avoid pencil or erasable pens, which can be altered.
• Do I need to endorse a check I'm depositing at an ATM or by phone? Usually yes, plus specific wording your bank requires — the app or screen will tell you.

The bottom line

Endorsing a check just means signing the back in the marked box to authorize payment. For everyday deposits, write 'For deposit only' and sign underneath — it's the safe default that keeps a lost or stolen check from being cashed by anyone but you. Sign your name the way it appears on the front, use blue or black ink, and never leave a plainly-signed check lying around. Ten seconds, done.
