Signatures being mandatory was temporarily suspended during Covid but this is no longer the case. Even then carriers would often put a code on the receipt indicating it was delivered. All certified return receipts are now again supposed to be signed or stamped. I have always recieved a stamped receipt when filing paper returns even during the two years of Covid - but not this year. If you have any proof to back up your claim that a sig/stamp is no longer part of the required mailing process please share.
Thanks.
