Mail routing numbers
Zip codes are the five-digit numbers that identify postal delivery areas in the United States: What's your zip code?
The system divides the country into geographic zones, with numbers generally increasing from east to west.
Extended zip codes add four more digits for greater precision.
Knowing someone's zip code reveals their approximate location and, by extension, their socioeconomic context—some zip codes carry prestige while others signal disadvantage: She moved to a better zip code.
