我觉得现在的平常用法里 zip code = postal code
Zip Code
A trademark used for a system designed to expedite the sorting and delivery of mail by assigning a series of numbers to each delivery area in the United States.
A ZIP Code is the postal code used by the United States Postal Service, which always writes it with capital letters. ZIP is an acronym for the Zone Improvement Plan, but was also meant to suggest that mail travels more efficiently (and therefore faster) when senders use it. The basic ZIP Code format consists of five numerical digits. An extended ZIP+4 code includes the five digits of the ZIP Code plus four more digits which allow a piece of mail to be even more accurately directed to a very small geography. ZIP Code was originally registered as a trademark by the U.S. Postal Service, but its registration has since expired.
The term "ZIP Code" is also used in the Philippines to name its postal codes. The Philippine ZIP Code is used by the Philippine Postal Corporation. Unlike American ZIP Codes, Philippine ZIP Codes are four-digit numbers without any extensions. While the cities of Metro Manila use more than one code, towns and cities outside Metro Manila are assigned only one code for every town and city.
