Address Validation

Postal Address Verification (PAV)

What is Address Verification?

Address verification is a process that compares an address against the official USPS database and tries to find a match. If a match is found, it means that the address is deliverable. If an address is not found, address verification software will correct the address, if applicable, and then compare it again against the database. This is part of a process called the Data Hygiene process, which keeps addresses and contact data listed in the USPS and other databases accurate.

How Does the API Verify Addresses?

It takes three steps for CDYNE’s Postal Address Verification (PAV) API to verify your postal addresses. Why three steps? Because verification alone doesn’t guarantee deliverability.

3. Validate

Validation uses the USPS database to ensure address deliverability.

What Does CDYNE’s PAV API Do?

Postal address verification saves time, money, and resources by verifying addresses for deliverability before mail and packages are sent out. We help businesses ensure they have accurate data and successful mailing campaigns. To achieve this, our PAV does all of the following.

  • Corrects spelling errors
  • Formats with USPS capitalization
  • Fixes incorrect abbreviations
  • Formats ZIP Codes to ZIP+4
  • Identifies missing information

Address Verification FAQs

Postal Address Verification (PAV) is an API (Application Programming Interface). It allows a business’s IT department to configure the Web Service on a web page, application or database with a few lines of code. There is no software to buy or install.

Our API delivers address results in a fraction of a second.

We receive updates from USPS once per month.

The API can be consumed with any programming language that supports REST or SOAP. See our Quick Start to see examples and a how-to guide on implementation.

Not at this time. CDYNE offers this API as a web service call requiring some coding to consume the API. However, you can save returned results to a database for your records.

Emergency support is available 24/7. Please see our Contact page for more information.
