What is Address Correction?

When the original ship-to address on mail or a package is incorrect, it must be corrected before delivery. This process is called address correction. To be considered correct, addresses must not only be exact, but also in the format required by the national postal authority, the United States Postal Service (USPS).

How Does the API Correct Postal Addresses?

The Postal Address Verification (PAV) API fixes postal addresses in three basic steps.

1. Standardize

Standardization formats your addresses to meet USPS standards.

Location pinpoint a magnifying glass

2. Correct

Correction identifies and corrects wrong address information.

3. Validate

Validation uses the USPS database to ensure address deliverability.

Why the Three-Step Process?

Correction alone doesn't guarantee deliverability or validity, which is why CDYNE's PAV API uses (1) Standardization, (2) Correction, and (3) Validation.
