Why USPS Address Validation Matters for W-9 Collection

Introduction

Collecting vendor W-9s can be one of the most repetitive and error-prone parts of accounting and compliance work. Even if you’ve automated reminders, there’s one small but critical detail that can cause big problems: vendor addresses.

A mistyped street name, an incomplete ZIP code, or an outdated address doesn’t just waste time it can delay onboarding, create back-and-forth emails, lead to 1099 returns, and cause issues like returned mail or undelivered forms.

That’s why we built USPS Address Validation directly into GetW9.

The Hidden Cost of Bad Vendor Data

Time wasted: Teams spend hours correcting invalid vendor addresses before year-end.
Delays: Payments or 1099 filings can be delayed because of incomplete vendor records.
Frustration: Controllers and bookkeepers end up chasing corrections instead of focusing on higher-value tasks.

How USPS Validation Works in GetW9

With the new update, every vendor W-9 submitted in GetW9 is automatically verified against the United States Postal Service (USPS) database.

✔️ Street names and zip codes are corrected instantly
✔️ Addresses are standardized to USPS format
✔️ Vendors get fewer rejections, and you get clean data from day one

There’s no extra step for your team validation is built directly into the workflow.
