MidAmerica Lists offers the high quality postal processing services you need for fewer wasted mailings and maximum postal discounts. Approximately 20% of consumer addresses and 30% of business addresses change each year.

NCOA Processing
The National Change of Address (NCOA) database is a file of individuals, families and organizations that have moved from one address to another. The file includes the old "moved from" address as well as the new "moved to" address.

LACS Processing
Many communities across the country have changed from rural route box numbers to city style addresses. Locatable Address Conversion System (LACS) processing is a service that converts these old, invalid addresses on your database to the new and correct addresses that exist on the LACS file.

DSF Processing
The Delivery Sequence File (DSF) is a complete address file of every valid delivery point in the U.S. DSF helps you qualify for postal discounts by standardizing addresses and assigning ZIP+4 and Carrier Route codes. Records that do not match DSF have a high probability of being undeliverable.
