Address Standardization

Address standardization is an integral part of Anchor’s NCOALink® solution

With each NCOALink® process run, the following address standardization products are included and are used to provide a deliverability grade on each address.

CASSTM

(Coding Accuracy Support System) provides the standardization of addresses into the standard USPS® format, adds the five-digit ZIP, ZIP+4® codes, delivery point and carrier route codes.

CASSTM Features & Benefits
  • Standardize your addresses to the USPS® format, and improve NCOALink® and other hygiene matches
  • Qualify for USPS® automation and presort discounts
  • Append congressional district and county codes
  • Dedicated customer support

DPV®

(Delivery Point Validation) will indicate whether an address is a deliverable address, based on USPS® National Address File. In addition, we assign a mail deliverability index to every address in your database to indicate which addresses are deliverable and which are not.

LACSLink®

The Locatable Address Conversion System is a database of converted addresses that primarily arise from the implementation of the 911 system. 911 address conversions normally involve changing rural-style addresses to city-style addresses. Conversions may result in the renaming and/or renumbering of existing city style addresses. LACSLink® reduces undeliverable mail by providing the most current address information for matches made to the LACSLink® file.

SuiteLink®

SuiteLink® is a USPS® database containing business addressing information specifically identified as high-rise default records because of CASSTM processing. SuiteLink® will append the secondary (suite) information to a business address providing the input address is determined to be a high-rise default record. The SuiteLink® product will enable customers to provide improved business address information by adding known secondary (suite) information to business addresses.

The process provides the required CASSTM certificate – PS Form 3553

Anchor updates the ZIP+4® directory monthly to provide the most accurate data available.
