Description

The County Project's goal is to improve address quality in both of our databases by resolving addresses that differ and reviewing congressional and county code differences. Benefits include:

  • The service is free. County addressing authority may submit their file up to once a year at no cost.
  • Identifies "No Match" address records that do not match the Address Management System (AMS) database.
  • Identifies congressional district variance records which provide the opportunity to identify specific records where the congressional district requires review by both the addressing authority and the USPS for possible correction.
  • Identifies county variance records which provide the opportunity to identify specific records where the county data requires review by both the addressing authority and the USPS for possible correction.
  • Returns all matched addresses in USPS standardized address format including the ZIP+4 ultimately reducing the mailing costs associated with Undeliverable-As-Addressed (UAA) mail.

The Process

  • County addressing authority completes PS Form 5118, County Project Web Access Request Form, and faxes to the NCSC.
  • NCSC confirms requester as official local addressing authority with local AMS office.
  • NCSC processes approved applications and notifies requester.
  • County submits file on CD/DVD media via U.S. Mail or sends encrypted file via email.
  • NCSC sends email notification when process is complete with encrypted file as an attachment.

Processed files will contain the following:

  • Matched, standardized addresses
  • "No Match" list
  • Congressional variances
  • County variances
  • Missing and Invalid Secondary files

Getting Started
