Credit Union question

I recently joined a credit union. The problem is, the credit union I joined doesn’t have an ATM available after business hours. It’s inside. (Dumb, I know.)
Concerning deposits only (NOT withdrawals), I know you can’t deposit money at a BofA if your account is at US Bank. But I’ve heard that all (or most) credit unions are all part of the same network. So, if I want to make a deposit after hours, can I use the ATM of a different credit union or does it work the same as a regular bank?

I am able to use another Credit Union’s ATM to make deposits. My credit Union is part of the Co-op network, I believe, and there’s no fee involved for either deposits or withdrawals.

ETA: Here’s a link to find a Co-op network ATM near you. Check for the Co-op network symbol on your card. ETA2: My Credit Union is a couple thousand miles from where I live.

This hasn’t come up for me, as there’s only one credit union in my county as far as I know.

Maybe this site can tell you if your CU is in their network: http://www.co-opnetwork.org/

Thanks to both of you for the link. Mine is part of the Co-op network as well. That site answered my question. Thanks again.

Doesn’t your credit union have a night depository slot outside? Most banks and credit unions have had those forever.
