10025

10025 is the zip code for southern Morningside Heights and the northern part of the Upper West Side. But it's not Columbia's zip code; that's 10027. Even if you live in a dorm (like McBain or Nussbaum) that's physically located in the 10025 area code, your mailing address will still be 10027. Confusing, right?

The closest post office for the 10025 zip code is located at 534 W 112th St, between Broadway and Amsterdam.
