ZIP code
A ZIP code is a series of letters and numbers used by postal services to efficiently identify specific geographic areas within a country. In the United States, ZIP codes help sort and route mail by pinpointing neighborhoods, towns, or city sections. They improve delivery speed and accuracy by organizing addresses systematically. Think of a ZIP code as a unique code that tells the postal system exactly where a package or letter needs to go, much like an address but more concise and precise to streamline the sorting process.
