Dan - I am referring to the postal zone codes that were in effect BEFORE the Zip Codes were instituted. As I recall, they were 1-digit and 2-digit numbers, and they may have only been used for the larger cities. Also, and again I could be wrong, but I think the old zone codes were incorporated into the Zip Codes as the last 2 digits of the Zip Codes. See the vintage WWII-era pic below in which the address for the Cleveland Vault Co. is 8616 Buckeye Rd., Cleveland 4, Ohio.
