Understanding Westchester, NY Zip Codes

Zip codes, an acronym for Zone Improvement Plan, are a system of postal codes used by the USPS.

Westchester County's zip codes are not necessarily aligned perfectly with town or city boundaries. You might find that one town spans multiple zip codes, or conversely, a single zip code might cover parts of several adjacent towns. This is due to the historical development of postal routes and delivery efficiency.

How Zip Codes Are Assigned

Zip codes are assigned by the USPS based on population density, mail volume, and geographical considerations. The five-digit system starts with a '0' for the Northeastern United States, and Westchester County falls within this region. The subsequent digits further refine the geographic area.

For Westchester, you'll find codes generally starting with '105', '106', and '107'. For example, '105' often signifies areas in the central and southern parts of the county, while '106' might indicate White Plains and its surroundings, and '107' could point to Yonkers.

The Importance of Accurate Zip Codes

Using the correct zip code ensures timely delivery of mail and packages. It also plays a role in determining local services, such as emergency response times, school district assignments, and even eligibility for certain local programs or deliveries. An incorrect zip code can lead to delays, misdeliveries, or even returned mail.
