NCOA Address Validation

NCOA address validation - Before processing your NCOA update, TrueNCOA must first verify, validate, and perform hygiene on your input records according to USPS standards. In this post, we provide an explanation of this process and provide some helpful links to some of the resulting error and warning codes related to deliverability that you may receive in your export file.

NCOA & CASS Certification

The USPS Coding Accuracy Support System (CASS) corrects and standardizes addresses, adds missing address information such as ZIP codes, cities, and states to ensure the address is complete, performs delivery point validation to verify whether or not an address is a deliverable address, and checks against the USPS Locatable Address Conversion System, updating addresses that have been renamed or renumbered. Because this process saves the post office time and money due to reduced sorting and undeliverable mail, mailers who use it can qualify for bulk mailing discounts. Please see the "About NCOA" section of our FAQ for additional information regarding the NCOA process.

An example of what CASS software will correct in an address

Input

1010 Lake
Oake park IL

Output

1010 Lake St
Oak Park IL 60301-1102

It corrects city name, address street suffix, ZIP code, and ZIP+4 add-on, and it identifies the address as a business. You can read more about identifying Residential vs. Business addresses here.

NCOA Delivery Point Validation

Delivery Point Validation or DPV checks addresses against the USPS database to determine deliverability. Matching records are marked valid. If they have no matching entry, they are marked invalid with a corresponding note and cannot be delivered. The process also cleans up and formats the address according to USPS standards to ensure deliverability and qualify mail for bulk discounts. You can read more about how to identify invalid addresses here, and to see more detail on DPV notes, check out our data dictionary here.

CASS Errors and Warning Codes

Even if CASS determines a record is valid, it may still alter or add part of the address. When this occurs, an error or warning code is entered.  Please see our data dictionary for a complete list of errors and warning codes that could be attached to a record during the validation process.
