National Change of Address (NCOA)
Over 40 million Americans change addresses annually, which creates formidable obstacles in maintaining a high-quality mailing list that tracks customers who move. The National Change of Address (NCOA) program makes change-of-address (COA) information available to mailers to help reduce undeliverable or duplicate mail pieces. NCOA service is a comprehensive program that aids mailers in identifying changes of addresses before mail enters the mainstream.
Input address information provided by a mailer to the NCOA licensee is first standardized to conform to USPS requirements, including the ZIP+4 code. Once the address has been standardized and the ZIP+4 code applied, an attempt is made to match the address against the NCOA File, which contains approximately 152 million records or 48 months of permanent address changes. Address change information is derived from the PS Form 3575, Change-of-Address Order, filed by relocating postal customers. If an exact match is made with the old address information in the NCOA File, then the NCOA licensee is permitted to provide the move information (new address) to the mailer.
NCOA helps reduce undeliverable-as-addressed mail by correcting input addresses prior to mailing. Since 1986, this service has saved mailers millions of dollars that otherwise would have been wasted in materials and postage.
NCOA provides the following benefits to mailers:
- Reduces undeliverable mail by providing the most current address information for matches made to the NCOA File.
- Prevents duplicate mail pieces or re-mailings after address corrections are received because the address correction is applied prior to the mailing.
- Reduces mailer costs by reducing the number of undeliverable and duplicate mail pieces by using most current address information.
- Provides the opportunity for faster product/service marketing through accurate mail delivery.
Your file is compared to the USPS master-addressing file to validate and correct street numbers (based on allowable ranges) and street names, state abbreviations, 5-digit ZIP codes, carrier route codes and the USPS Delivery Point Bar Code. Corrections are made automatically and with 99% confidence. Records that cannot be corrected are marked as invalid and left unchanged.
Evolving strategies – plan for the unexpected. When establishing a yearly marketing plan or strategy, you need to take variations into account. Always intend to have a small reserve budget specifically for new tests (format, audiences, offer, channel) in order to fine-tune and optimize.
