With an unparalleled physical reach and frequency, USPS is delivering "Beyond the Mail" by offering a suite of addressing and geospatial data products geared towards customers with expanded use cases.

    Dear Customers,

    The USPS is delivering Beyond the Mail!

    A suite of additional new addressing and geospatial data products is coming available to customers with expanded use cases.

    Visit Beyond the Mail | PostalPro (usps.gov) for the products currently available:

    • USPS Post Office & Collection Box Location Data (https://postalpro.usps.com/gis)  
      • Datasets containing the specific coordinates of United States Postal Service Post Offices and blue collection boxes as well as detailed information around specific services offered and hours of operations or collection times.
    • USPS Occupancy Trends (https://postalpro.usps.com/ot)
      • Populated using vacancy data collected by USPS® carrier operations, the USPS Occupancy Trends product provides an aggregate count of vacant addresses by ZIP Code™, USPS carrier route, county, and congressional district. Additionally, the count can be viewed by census tract, group and block as a fraction of total possible deliveries.
    • USPS Population Mobility Trends (https://postalpro.usps.com/pmt)
      • A tabular dataset built upon aggregated USPS National Change of Address data and 2020 Census demographics (income, age, household size). The data is aggregated to highlight the 9 highest volume destination ZIP™ Codes (3 local, in-state, and out-of-state) people are migrating to for each source ZIP. Census demographic data is included for the top 3 volume breakdowns by demographic category (income, age, household size).
    • NEW! USPS Emerging Roads: (https://postalpro.usps.com/er)
      • The Emerging Roads product provides new and existing roads with corresponding attributes based on new delivery points added to the system and USPS® GPS data from carrier activity.
    • NEW! USPS ZIP Code Boundaries: (https://postalpro.usps.com/zcb) A national ZIP Code map utilizing USPS delivery address and location information to ensure extremely accurate boundaries. Temporal fluctuation is based on changing delivery distribution for new or changed delivery locations.

    Additional product that is coming soon:

    • USPS Geocoding API: COMING SOON
      • An API in which an input address is translated into geolocational front door and mailbox latitude and longitude coordinates with address matching notes.

    We look forward to serving your business needs.
