You can mail deposits to a bank for deposit to your account. Speak the manager, and let them know you will be doing this. When you endorse the checks, you will need to use a restricted endorsement. “For deposit only to account 12344567” Then endorse the check. Make copies of the checks in each deposit. Depending on your bank, they may charge you a small fee for doing this. If your checks are all coming from a single source, they may agree to do direct deposit for you.
