Which type of identification is NOT acceptable for cashing a postal money order?

The reason that an expired ID card is not acceptable for cashing a postal money order lies in the identification verification protocols established by the USPS. When cashing a postal money order, the individual must provide a valid form of identification to ensure that they are authorized to receive the funds. An expired ID card does not meet these standards, as it no longer verifies the current identity of the individual.

In contrast, valid forms of identification, such as military IDs, driving permits, and state-issued IDs, provide current information about the individual, including their name, photo, and sometimes their address, which are essential for the verification process involved in cashing a money order. Therefore, the integrity and reliability of the identification must be maintained, which is why an expired card is not acceptable.
