Send Mail to the Correct Address Every Time with ACS™
Address Change Service (ACS™) is a post-mailing process used to update address information and allows mailers to receive change of address (COA) information electronically. ACS™ provides you with a list of undeliverable addresses and a reason why the mailpieces could not be delivered to those addresses.
Since updates are made electronically, it significantly reduces the number of manual address notifications and updates, making it an efficient and cost-effective address correction service.
Seamlessly integrate with the USPS Address Change Service (ACS™) to receive automated notifications of post mailing address changes and undeliverable mail pieces.
We also offer USPS Secure Destruction services for returned mail, ensuring compliance and data protection while reducing your reliance on physical mail returns.
