Frequently asked questions
What is business verification?
Business verification checks submitted company information against independent source records before the business moves further through an operational workflow. Zenwork verifies information such as TIN and legal name against IRS records, addresses against USPS data, and entity status against Secretary of State records.
What information can be checked when verifying a business?
Zenwork supports checks for TIN and legal name, USPS address, Secretary of State business status, tax-exempt status, FATCA/GIIN status, sanctions and watchlists, public records, and the Death Master File. Each check returns its own source result.
How does business verification support vendor or seller onboarding?
Business verification moves source checks earlier in onboarding. TIN mismatches, address issues, entity-status results, and sanctions or watchlist findings can surface before the business progresses further, reducing the number of records that need manual investigation later.
What happens when business information does not match source records?
Each source check returns its own result, so one issue can be isolated without losing the results of completed checks. For example, a partial USPS address match can be routed for review while IRS TIN and legal-name verification or Secretary of State status results remain available.
Can business verification be automated through an API?
Yes. Zenwork supports API-based TIN Matching through synchronous and asynchronous workflows, as well as bulk processing. The IRS validation result and response code can return to the requesting system so verification can remain within an existing onboarding, vendor, underwriting, or payment workflow.
