Since 2002: Massive multi-sourced PCOA masterfile...

Proprietary Change of Address


Includes Address Updates from Utilities, Phones, Credit Cards, etc

Massive multi-sourced Proprietary Change of Address

It's estimated that over 1/3rd of Americans no longer report their moves to USPS

Why you need PCOA
NCOA is self-reported, so if your addressee doesn't report their move, that information simply will not be in the NCOA database. This means that there are many address updates you are potentially missing.

  • NCOA = 100% dependent on self-reported info
  • PCOA = Full NCOA + Updates from Utilities, Phone Carriers, Credit Card Processors, Magazine Subscriptions & more
Here's the challenge: USPS relies solely on postal customers filing change of address forms with the postal service when they move. Increasingly 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
  • Over a third of US movers do not notify the USPS
  • Proprietary multi-sourced dataset:
    • Utility company info
    • Phone carrier connects/disconnects
    • Magazine publishers (over 120)
    • Credit grantors
    • Retailers & catalogers
    • Third-party credit card processors
    • High-end purchases
    • Real Estate transactions & more
  • 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 5-20%
  • 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 our massive PCOA dataset. It's a proven technique that works.

One other thing, there will be issues with this data. There always is. Users should really have a last contact date or something similar to override some of these matches. Example: if our record comes back as a match from say 2 years ago, but you've had contact with the addressee in the last 12 months at a different address, then you should ignore our update from 2 years ago. Also, address updates from PCOA should never ever be used for Billing, Statements, Sensitive Material, Personal & Confidential, etc. It is simply not recommended.

How does it work?

  • Create your list (usually this means exporting it from your database)
  • Include any columns you may need in addition to Name, Address, City, State & Zip
  • Login anywhere on the website using your UserID & password
  • Click 'Proprietary Change of Address', Submit, then upload your list
  • Processing initiates moments after successful file upload
  • Names & addresses are matched against our national PCOA dataset
  • Fresh addresses are appended to your list with indicator of dataset source
    • Moves from NCOA flagged with 'Y'
    • Moves from PCOA flagged with 'P'
  • A mail deliverability score is applied to every address in your list
  • When processing is complete, receive Notification Email with download instructions

PCOA: Your database will thank you

NCOA alone is not a complete address update solution.

PCOA provides unmatched potential to update your addresses as much as possible.
