I want to write a check in the US, to be sent to the recipient via standard mail (USPS). What (and where) do I need to write on the check (in addition to the standard recipient name, $ amount, date and my signature) in order to protect it from being cashed or deposited by any person other that the intended recipient?
For example, if the envelope is lost in the mail and the check arrives at some stranger's hands, how do I guarantee that person cannot use (deposit, transfer, cash) the check?
