D. Jamison Cain
Deputy Special Assistant for Public Information

The Post Office Era

The rollout of the ZIP Code program was done in a very different (and much more effective way) way than previous campaigns. This was thanks in large part to D. Jamison Cain.

Cain came from Sumter, South Carolina where he worked in South Carolinian politics and newspapers. He came to Washington D.C. to cover Congress and got to know Lyndon B. Johnson personally during his time as Senate Majority Leader. During the implementation of the ZIP Code system he was Deputy Special Assistant for Public Information.

Frederick Kappel
Chairman of the Board for AT&T

The marketing effort was a joint project between the Post Office and AT&T. The story goes that J. Edward Day (Postmaster General) met Frederick Kappel (Chairman of the Board for AT&T) on a flight from Chicago to Washington D.C.

Day told Kappel that the Post Office was getting ready to launch a massive advertising campaign to promote their new address zoning system. Kappel advised caution and told him of the problems that AT&T faced when they introduced all-digital dialing and area codes.

Day welcomed any assistance. Soon after that flight a group of people from AT&T came to Washington D.C. with a proposal for a mascot based on the illustrations of Howard Wilcox that he created for Chase Manhattan (and AT&T had subsequently acquired).

The delegation from AT&T included Russ King (Head of the Yellow Page division), Gene Lepe (AT&T’s PR person) and Hal Saltsman and they met with James F. Kelleher (Day’s special assistant for public information), Assistant Postmaster General Frederick C. Belan and D. Jamison Cain.

The Post Office didn’t have the money for the ZIP promotional campaign so AT&T gave them $3 million in goods and services. For example, the stickers that you saw on mailboxes in the 60s, the Post Office ordered them and AT&T paid for them. AT&T was more than happy to help as the public was pretty upset with them over area codes and they thought that the Post Office implementing ZIP Codes would take a little bit of the heat off them.

ZIP Code Promotion Plan

The marketing plan was fairly comprehensive and is best described by a April 22, 1963 memo by Cain entitled ZIP Code Promotion Plan.

How Mr. ZIP got his name

The Post Office decided to kick off the new postal code system in Pittsburgh as they already had experience with postal codes during the war as they were a two-digit zone.

Back in 1943 during WWII some cities instituted two digit postal zones. This was because many of the experienced postal clerks had gone to war and the newer inexperienced workers were having trouble sorting the mail. With this system a two digit number comes after the city to assist the clerks in sorting.

Cain said “Okay, so what we’re doing here is, we’re improving on that two-digit zone”. So I said, “We’ll call this ‘Zoning Improvement Plan’, and we’ll shorten it to ‘ZIP Code: Zoning Improvement Plan Code”.

After they decided on the name for the new numbering system, Mr. P.O. Zone came up, and Cain said, ‘No, that’s awful’ and suggested they change the name to Mr. ZIP.
