Address validation is the last step in any Address Verification process.

After an address is standardized and corrected to make sure the address exists, it is then cross referenced against the latest United States or Canada Postal delivery database. This confirms not only that the address exists, but that the USPS and Canadian Post can deliver to it as well. Addresses that fall out of delivery range can be identified, therefore effectively eliminating extra costs associated with undeliverable mail. Address validation is the most cost-effective way to weed out bad addresses from your database or contact list.
