Address Change Service (ACS)
Address Change Service (ACS) is an electronic enhancement to traditional, manual
methods of providing change-of-address (COA) information to mailers. The system
is designed to reduce the volume of manual (hard copy) address correction
notifications handled by both the Postal Service and mailers while at the same
time centralize and automate the provision of address correction information to
mailers. Mailers add a unique code to the address area of their mailpieces to
identify them as ACS participants. As undeliverable-as-addressed (UAA)
mailpieces are subsequently processed at Computerized Forwarding System (CFS)
sites, this code prompts the CFS computer system to create an electronic record
of the customerís move information. These records are consolidated nightly at
the National Customer Support Center (NCSC) in Memphis and are provided to ACS
mailers according to a frequency determined by each mailer
ACS provides significant cost-saving benefits to mailers and the Postal Service.
ACS participants are able to use electronically generated address correction
information to update their mailing lists more easily and in a more timely
manner. The mailerís cost to receive electronic ACS notifications is $0.20 per
record; manual hard copy notifications are $0.50 per notification. This
front-end savings, coupled with the fact that electronic records cost
substantially less for mailers to process than labor-intensive manual mailing
list update methods, leads to a two-edged financial benefit for participating
The Postal Service reaps a dual
benefit from mailersí use of ACS as well. Electronic address information costs
considerably less to process and provide to mailers than manual notifications.
In addition, mailers who utilize ACS are able to update their mailing lists in a
more timely manner. This leads to an overall reduction in costly UAA mail volume
as fewer mailpieces must be handled multiple times by Postal Service personnel
Currently, ACS has over 3,000 participants representing over 4,200 active
participant codes across all mail classes. More than 119 million notifications
were provided in 1997, which represents a 6.5% increase over 1996.
