ZIP+4 Latitude and Longitude Database

Geocoded 9 Digit ZIP Code Database

Starting with the latest USPS ZIP+4 database containing over 47 million records, we match each ZIP+4 to its latitude and longitude coordinates. We have a high percentage of our records geocoded accurately at the ZIP+4 level (a record without an exact match will have the latitude and longitude of the ZIP Code). In order to keep the file size to a minimum, we’ve combined ZIP+4 ranges that have the same latitude and longitude. We currently have over 32 million because the file is so precise.

If you want to find the Latitude and Longitude from an address, this ZIP Plus 4 database is the correct product for you. Note: a ZIP+4 is usually a segment of one side of a street and may include many addresses. For that reason, it is not suitable for pinpointing exact addresses but is significantly more granular than normal ZIP Code geocodes.

ZIP+4 with Latitude & Longitude

As mentioned in the summary, we reduce the overall file size by combining ZIP+4 ranges within the same latitude and longitude. For example, an address with the ZIP+4 of 12345-0800 would match to the first record shown below because 0800 is within the range of 0001-0999.
