An ACS ID is the unique identifying number that every member is initially assigned when they first donate to Audubon. This will be the number that appears on the member's magazine and Chapter mailing labels. It is also the first column/field of the Chapter roster and change reports. The ACS ID is also used to look up a member or omit a member from mailing labels created through the Chapter Reporting System.
