What is dpv?

DPV stands for "Delivery Point Validation." It is a system used by the United States Postal Service (USPS) to verify the accuracy of a mailing address. This system checks if the address given by the mailer is an actual USPS delivery address or not. It also verifies if any changes were made to the address since it was entered into the USPS's database. DPV is particularly useful in preventing undeliverable mail due to address inaccuracies or changes. This technology is widely used in direct mail marketing and e-commerce transactions to improve the accuracy and efficiency of the USPS mail delivery system.
