In the U.S., ZIP stands for "Zone Improvement Plan," reflecting its purpose in organizing mail geographically. Postal Codes, on the other hand, may not have such specific acronyms but serve a similar purpose in facilitating mail distribution in countries like Canada (Postal Code), the UK (Postcode), and Germany (Postleitzahl).
