What is another word for zip code?
Pronunciation: [zˈɪp kˈə͡ʊd] (IPA) 
Zip code is a term that refers to a standardized system of postal codes that are used by the United States Postal Service (USPS) for sorting and delivering mail. However, there are other terms that can be used interchangeably with zip code. These include postal code, area code, and zip+4 code. Postal code is a more general term that is used in other countries besides the USA. Area code typically refers to the three-digit code used for phone numbers, but this term is sometimes used colloquially to mean zip code. Zip+4 code is an expanded version of the regular five-digit zip code that adds four additional digits to make the sorting process even more precise.
