Best Answer: The ZIP code is the system of postal codes used by the United States Postal Service (USPS). The letters ZIP, an acronym for Zone Improvement Plan,[1] are written properly in capital letters and were chosen to suggest that the mail travels more efficiently, and therefore more quickly, when senders use it.
The USPS provides a free online lookup tool for ZIP codes.

USPS style for ZIP is all caps, although style sheets for some publications use sentence case or lowercase.
