Get Started

What is Address Verification?

Address Verification is a critical service that checks and corrects recipient addresses to ensure they meet USPS CASS™ (Coding Accuracy Support System) standards. By validating addresses before mailing, you reduce the risk of undeliverable mail, save on postage costs, and improve overall mailing efficiency.

Who Uses Address Verification?

Businesses

Ensure invoices, statements, and marketing materials reach the correct addresses.

Government Agencies

Validate addresses for official notices, voter information, and tax notifications.

Educational Institutions

Verify addresses for admissions letters, transcripts, and alumni communications.

Individuals

Confirm address accuracy for personal correspondence, gifts, or legal documents.

Our Address Verification Offerings

User Interface (UI) Access:

Easy Upload: Effortlessly upload a CSV file containing recipient names and/or addresses to our user-friendly interface.
Quick Turnaround: Within minutes, our system processes the data, verifying and correcting addresses according to USPS CASS™ standards.
Downloadable Results: Once processed, an output file is generated, indicating which addresses have been validated and formatted correctly ("good") and which could not be validated ("unknown"). This file is available for download directly from the UI.

API Access:

Seamless Integration: For users who prefer automation, our API allows you to integrate address verification directly into your application or workflow, validating addresses in real-time as part of your letter request orders.
In-Line Validation: Addresses are validated and corrected as they are submitted, ensuring accuracy before letters are mailed.

Advanced Features

Enhanced Address Validation:

Our tracking portal offers:

Comprehensive Move Database: Beyond basic address validation, our service can cross-reference recipient names with a move database that tracks address changes dating back 17 years. This extensive coverage surpasses the USPS NCOALink® service, which only covers the past 4 years.
Detailed Classification: Addresses are categorized as "good" if they meet validation standards or "unknown" if they cannot be validated, allowing you to take appropriate action.
