PAV API
PAV (Postal Address Verification) is a CASS Certified™ API that allows you to standardize, correct, and validate U.S. and Canadian addresses in one step. Save time, money, and resources by verifying that addresses are deliverable before mailings or packages are sent out. PAV helps businesses ensure data quality for U.S. and Canadian customers. When verifying a Canadian address, the API will only verify the city, state, and ZIP Code. The province name must be abbreviated in order for PAV to append a missing ZIP Code to a verified Canadian address. CDYNE offers trial license keys for all web services so that you may test the APIs for free. Postal Address Verification (PAV) is an API (Application Programming Interface). The API allows a business's IT department to configure the Web Service on a web page, application, or database with a few lines of code. There is no software to buy or install, no complex system to learn, and the service's data is automatically updated each month.
