About Vendorville

Vendorville Directory is an independent data product: a verified list of the 759 Northwest Arkansas offices in the Walmart and Sam's Club supplier ecosystem, plus 1,077 named Walmart-facing contacts. It's built in Fayetteville, Arkansas, by Johnathon Williams and published by OddJar.

Why it exists

“I built this because the standard databases kept telling me Bentonville was empty. ZoomInfo files a brand's Walmart office under its Chicago headquarters; the local team never shows up. So I mapped the cluster myself — 759 offices, two independent sources each, re-verified quarterly.”

Who's behind it

Johnathon Williams is a software developer in Fayetteville, Arkansas, with more than 15 years of experience building web software, and runs OddJar, a small independent software company; Vendorville is its data product. Find Johnathon on LinkedIn.

How the list is built

Every company in the directory is confirmed by two independent sources from different origins — company sites, trade-association rosters, property and registry records, dated local job postings, and direct re-verification. A separate pass re-fetches the evidence for each new row and tries to knock it down. Contact emails are SMTP-validated independently. The full rules are on the methodology page, and the edition log records what changed and when.

Independence

Vendorville is not affiliated with, or endorsed by, Walmart Inc. It contains no Walmart confidential information; every fact comes from public or licensed sources. Free research on this site — the 2026 census and the supplier hub — is aggregate-only; the row-level file is the paid product.
