Address Hygiene – Cleansing
CHANGE OF ADDRESS PROCESSING  (COA) or (NCOA)

According to the United States Postal Service (USPS) over 40 million Americans change their address every year. This creates huge obstacles when trying to maintain an up-to-date mailing list.    The COA overcomes the obstacle by identifying addresses that have moved in the past 18 months; for small added fee you may go as far back as four years.    This simple – low cost service will give you great savings … via better deliverability and of course fewer returned “No-Longer-At-This-Address” mail pieces.

ADDRESS VERIFICATION – HOW TO PROVE THE ADDRESS EXIST

A big question facing mailers is how to prove that a given address is a valid address.   The solution is the DSF database … which contains every single domestic address in the U.S.   If your address is not on this file … then the address doesn’t exist!  

APARTMENT NUMBER APPEND

Apartment or suite numbers are frequently dropped or never captured on many mailing lists. Dirmark’s Apartment Append service can add missing apartment numbers to your file and can even correct addresses that have an incorrect apartment number.
By appending accurate apartment numbers, not only can you increase the “Moved to New Address” match rate, but your mail will also reach more customers thereby increasing your conversion rate. We use an apartment database that is sourced from transactional information and only includes verified addresses.
