Unlike postal codes in some other countries, US Zip Codes do not contain letters. Every delivery area in all 50 states (including Kentucky, Massachusetts, Virginia, Vermont, Nevada, Kansas, Louisiana, Nebraska, New Hampshire, and Rhode Island) plus territories like American Samoa, the Federated States of Micronesia, and the District of Columbia has at least one assigned ZIP Code to help find specific destinations.

23401 is a US ZIP Code assigned to a delivery area in the eastern section of Virginia. Specifically, this number corresponds to Keller, a city on Virginia’s Eastern Shore region, part of the Delmarva Peninsula. This zip code is not associated with West Virginia or other states like Kentucky or Alabama.

US ZIP codes are five-digit numbers identifying specific delivery areas throughout the United States. While they generally follow state boundaries, there are interesting exceptions where ZIP Codes serve communities across state lines.

For example, some residents near the West Virginia border might share a ZIP code with neighboring communities in Maryland or Virginia, depending on mail processing logistics.

When searching for information about a particular area, you always have the option to look up the official US ZIP code boundaries through the USPS website, which shows exactly which streets and addresses belong to each US ZIP code region.
