Address Change Service (ACS) is a trademark of the US Postal Service.
Traditionally you would have to signup for a MailerID, plus setup and manage your own Address Correction (ACS) services with the US Postal Services. We are pleased to be able to offer you this service directly!
With our free ACS services, instead of getting a stack of mail returned with yellow stickers on them, you get an email instead.
We are also offering 48 month NCOA as our primary National Change of Address service. That means you will get more pieces delivered to your clients and fewer pieces returned to you.
