APIs

The Address API provides validation and standardization of USPS domestic addresses, city and state names, and ZIP Codes. When a valid address, city, and state are provided, for instance, the API will return the standardized address along with the 11-digit delivery point ZIP Code. This API also supports lookups of city and state names by ZIP Code or ZIP Code by city and state names. This functionality enables shippers to validate and standardize address information during order entry. Thus, saving time and money by reducing shipping delays and errors due to incorrect or improper address information.

The ZIP Code lookup finds valid ZIP Codes for a City and State.  The City/State lookup provides the valid cities and states for a provided ZIP Code.  The Address Standardization API validates and standardizes USPS domestic addresses, city and state names, and ZIP Codes in accordance with USPS addressing standards.  The USPS address standard includes the ZIP+4, signifying a USPS delivery point, given a street address, a city and a state.
