Yep. Those are keyring return tags. They would be mailed out after you got your new yearly license plates from the BMV. Disabled American Vets sent them as a gift hoping you would send them a donation. When you lost your keys, a finder would drop them into a mailbox and the system would return them to you. As RgnFn said, they are after 1963 since they have a zip code. I have over 100 of those little tags in various styles.
