Seven Tips to Stem Losses from Unaccounted Movers

2. Use Address Correction Service (ACS). The USPS’ ACS involves putting special wording and coding on mailpieces that instructs the USPS to compare the mailed address to the mover database and to notify the mailer of changes. The downside is that it’s more expensive than NCOALink and involves more work for the mailer to apply the new information. But it’s still a valuable tool because it provides timely information and the matching can be less strict than NCOALink.
