When did banks start requiring people to endorse checks for deposit?

I’m currently a teller, and today I had an older lady, probably in her late 60s, come in to make a deposit. Her check wasn’t endorsed, so I asked her to sign it. She responded, “I’m not cashing it.” I explained that even for a deposit, the check still needs an endorsement. My coworker then remarked that because she’s older, she might have an old-school way of thinking, and he admitted he’s the same way.

When I was young, my grandmother took me to the bank and explained various processes to me. She always emphasized that a check should be endorsed, whether depositing or cashing it. I’m puzzled as to why some people make such a big deal about signing their checks for deposit. I’m curious—was there a time when endorsing checks for deposit wasn’t necessary, or am I remembering it correctly?

Hellos, The exact date of when endorsing checks became mandatory is a bit fuzzy, but the practice likely emerged alongside the widespread use of checks themselves.

Forever ago, been in banking for 20 years and have always been that way long before I started. The Uniform Commercial Code is like 70 years old. Checks always have to be endorsed, and as a teller it’s your responsibility, no one else’s end, to ensure you have gathered the proper endorsement to the best of your ability that the endorsement is genuine.

It must have emerged alongside the widespread use of checks themselves. The history of checks traces back to the 17th and 18th centuries, and endorsements likely served as a security measure from the beginning.
