Another decision needs to be made for move update. Full service IMb adds a fifth ancillary service endorsement for mail undeliverable as addressed (UAA). Electronic Service Requested printed on the mail piece tells the letter carrier that the specific disposition of the UAA mail piece—address service, change service, forwarding service, return service, or temporary return service—will be found within the IMb. Mailing service providers will likely need a scanner or barcode identification device to decipher the IMb to be sure that the correct UAA endorsement is within the IMb, especially since there is potentially a wide range of costs to the mail owner, depending on which UAA endorsement is specified.
Happy 50th Birthday, Mr. ZIP
In 1963 the USPS (then called the Post Office Department) implemented the Zone Improvement Plan as a way to deal with inefficiencies in the zoning system caused by rising mail volume. In 1962, Postmaster James Edward Day identified the need for a more effective postal zoning system, and on July 1, 1963 the Zone Improvement Plan (ZIP code) was introduced.
As part of its promotional campaign to encourage use of ZIP codes, the USPS adopted the cartoon figure Mr. ZIP as the trademark for the Zone Improvement Plan. Mr. ZIP was designed by Harold Wilcox, son of a letter carrier and on the staff of the Cunningham and Walsh advertising agency for use by Chase Manhattan Bank in New York. The American Telephone and Telegraph Company (AT&T) acquired the design from the agency and gave it to the Post Office Department at no cost. After some modification, Mr. ZIP made his debut in October 1962 at a conference of postmasters.
Mr. ZIP was a prominent part of Post Office advertising throughout the 1960s. Research showed that within four years of Mr. ZIP’s debut, eight out of 10 Americans knew who he was and what he stood for. (For a video glimpse into the ZIP code campaign, go to MyPRINTResource.com/10983257.)
In the 1970s, use of ZIP codes began to approach 100 percent and the advertising campaign was scaled back. In 1983, after 20 years of use, Mr. ZIP was retired, no longer needed because the USPS had implemented ZIP+4.
Every location in the US has a nine-digit code: the first three digits are the general region or city; digits four and five are the delivery area (post office or neighborhood); digits six and seven are the sector (blocks); and the final two digits are the side of the street.
Today there are a total of 41,810 ZIP codes. California has the most ZIP codes (2,602); Rhode Island has the fewest (90). The lowest ZIP code is 00501 (a unique ZIP code for the Internal Revenue Service in Holtsville, NY). The highest ZIP code is 99950 in Ketchikan, Alaska.
