How Address Correction APIs Works

A few different types of address correction APIs are available, but they all work to clean up and correct addresses entered by users. This is important because it helps ensure that parcels or letters arrive at their intended destination, and it can also help businesses save money on postage.

The USPS Address Correction API (PAV API) can correct an address, verify an address, or standardize an address. One common type of address correction API is the USPS Address Correction API. CDYNE offers this service, which can be used to correct the United States and Canadian mail addresses.
