How does an address lookup API work?

An address lookup API is a web-based interface that allows you to access up-to-date information about addresses and properties. With an address lookup API, you can submit an address or property identifier and receive back detailed data about the location. This data can include the current occupants of the property, the sale history of the property, as well as other useful information.

An address lookup API works by taking a street address and returning a zip code, city and state. The most common form of address lookup is a city lookup. A city lookup is an easy way to determine if an address is in a certain city/zip code/county.

Address lookup APIs are powered by geocoding technology. Geocoding is the process of converting a street address into a geographic coordinate.
