Address Validation

Address Validation: A Critical Step in Data Accuracy and Delivery Success

Address validation plays a crucial role in ensuring that your mail, packages, and communications reach the right customers. At its core, address verification is the process of confirming that a given input address exists, follows proper formatting, and is deliverable. Businesses that overlook this step face increased costs, delayed deliveries, and unhappy customers.

Anchor Software provides powerful address validation software solutions—MaxCASS OS, MaxCASS Plus, and AddressPro—to help organizations across industries maintain high-quality address data.

Why Address Validation Matters

Reduce Failed Deliveries and Boost Customer Satisfaction

Incorrect or malformed addresses result in failed deliveries, which waste time and money. Using a robust address verification tool ensures each street address is real, complete, and valid—improving customer satisfaction and shipping package efficiency.

Eliminate Undeliverable or Incomplete Addresses

Many businesses unknowingly store incomplete USPS addresses or bad addresses in their systems. A quality address check tool can flag, fix, or remove these issues. Appended missing data, such as ZIP codes or apartment numbers, helps create valid addresses from incomplete ones.

The Address Validation Process

Step 1 – Address Parsing and Standardization

The first step involves breaking the input address into individual address components, such as:

Street direction
House or unit number
City
State
ZIP code

Once broken down, these elements go through address correction. An innovative address standardization tool corrects common mistakes (e.g., changing “Main Strt” to “Main St”) and adds missing information, applying USPS-approved formatting.

Step 2 – Verification Against USPS Databases

After standardization, the system checks the address against official USPS databases. If a match is found, the address is valid and deliverable. If not, it could be due to:

A non-existent location
A newly constructed home not yet registered
A P.O. Box or an unoccupied building

This process also identifies undeliverable addresses, preventing wasted resources.

What is CASS Certification?

Ensuring the Highest Standard of Address Accuracy

The Coding Accuracy Support System (CASS) is a USPS certification program that validates the accuracy of address validation tools. Software must be recertified annually to comply with evolving postal standards.

Anchor Software’s CASS Certified solutions not only verify addresses but also:

Correct and format addresses to USPS standards
Append missing data like cities or ZIP codes
Confirm delivery point validity
Use LACSLink® to detect newly changed rural-style to city-style, renamed, or renumbered addresses

The Benefits of Accurate Address Data
