4-year USPS NCOA + 10 year PCOA masterfile...Since 2002

Proprietary Change of Address


10 years of multi-sourced Change of Address

Why you need PCOA
Most organizations have come to rely on the USPS National Change of Address service as a tool for identifying movers and updating address information prior to mailing.

While this works most of the time, the problem is this: the USPS relies solely on postal customers filing change of address forms with the postal service when they move. Increasingly however not all movers fill out this form, meaning that NCOA alone cannot provide all new address information. Compounding this problem, strict USPS matching requirements means you are potentially missing many, many address corrections.

NCOA alone is not a complete address update solution

  • PCOA adds movers that cannot be corrected using USPS data alone
  • Approx 27% of US movers do not notify the USPS
  • Proprietary multi-sourced dataset:
    • Utility company info
    • Phone company connects/disconnects
    • Magazine publishers (over 120)
    • Credit grantors
    • Retailers & catalogers
    • Third-party credit card processors
  • Almost 140MM COAs (old and new address pairs) going back ten years
  • Over 750k new and unique COAs added monthly
  • PCOA increases the number of corrected movers by 5-10% or more
  • Reduce wasted mailing expenses & enhances marketing effectiveness

PCOA: Powerful dual-level processing
NCOA is the first step in this process, followed by PCOA.

Records that do not match in the first step (NCOA) are automatically routed to the second step (PCOA), which goes through 10 years' worth of change of address data. It's a proven technique that works.

For a complete change of address solution, use our Proprietary Change of Address service combined with NCOA. By using the combination of NCOA + PCOA, you will identify movers and obtain new address information prior to mailing.
