This site is an independent ZIP code directory and is not affiliated with the United States Postal Service. It holds no employee, payroll or personnel information. If your search combined the two topics, one of the following is probably what you need.
Looking up a ZIP code
The official USPS ZIP Code Lookup finds the ZIP and ZIP+4 for a street address, lists the cities in a ZIP, and confirms whether a ZIP is valid. Our ZIP code lookup adds place, county and map reference data for every five-digit code.
USPS employee resources
Postal employees access pay, benefits and scheduling information through the USPS employee portal, LiteBlue, using their employee ID and password. Personnel questions go through the Human Resources Shared Service Center listed inside that portal. Never share employee IDs or passwords with third-party sites.
Finding a post office
To locate a post office by ZIP code, use the USPS “Find Locations” tool on usps.com, which lists hours, services and PO Box availability for each facility.
