Next, the NCOA licensee will run your lists against the NCOA file, correcting addresses and adding ZIP+4 codes where they're missing.
Depending on the quality of the list you're mailing to and the sophistication of your--or your lettershop's--mailing equipment, you can use delivery point barcodes or legible, properly formatted address blocks with ZIP+4 codes (which enable the Post Office to create the delivery point barcodes) and receive significant discounts.
Once this process is complete, addresses that were appended with ZIP+4 codes
are now deliverable.
Other vital information on the file includes carrier routes, delivery sequence numbers, ZIP+4 codes
, vacancy codes, delivery type codes and seasonal codes.
For example, once your list is clean and contains ZIP+4 codes
, you can spray mail with delivery point barcodes, enabling the USPS to automate the handling of your mail.
This will verify ZIP information and insert ZIP+4 codes
so that Delivery Point Barcodes can automatically be printed on the outgoing mailer during the address imaging process.
