Supported categories: company formation and ownership (certificates of incorporation, shareholder certificates, operating agreements), tax verification (W-9, EIN letters, W-8BEN/W-8BEN-E, ITIN letters, state tax registration, federal tax returns), bank verification (statements, verification and reference letters, direct deposit and ACH forms), and PCI DSS compliance (SAQ A, A-EP, D).
• US Company Registry Check — look up a company in the US Secretary of State registry by name or SOS ID to verify its registration status, registered agent, and formation details.
• US TIN Verification — check that a company’s legal name and TIN/EIN match IRS records.
