Verification infrastructure for people and payees.
Real-time and bulk TIN matching, OFAC and global watchlist screening, I-9 employment eligibility, tax transcripts, and public records — the checks that sit upstream of onboarding and filing, in one product instead of separate vendor logins.
What this replaces
- A standalone TIN matching API or portal
- A separate OFAC / sanctions screening subscription
- A separate I-9 / employment eligibility vendor
- Manual IRS transcript requests
What's inside
Real-time and bulk TIN matching
Check a single TIN in under a second or submit a bulk file for thousands of payees — same IRS-backed match, same results format.
- Sub-second single-TIN lookups
- Bulk file upload with async results
- Full match history and re-check on demand
OFAC and global watchlist screening on every check
Every TIN check can also run against OFAC sanctions lists and other global watchlists, so tax-identity verification and sanctions screening happen in the same pass instead of two separate tools.
- OFAC Specially Designated Nationals & consolidated sanctions lists
- Additional global sanctions and watchlist coverage
- Screening results logged alongside TIN match history for audit
I-9 employment eligibility verification
Collect and verify I-9 documentation as part of onboarding, with status tracking alongside your other checks.
- Digital I-9 collection
- Document verification workflow
- Status visible in the same dashboard as TIN, screening, and records checks
Tax transcripts and public records, on demand
Pull IRS tax transcripts and public records checks without leaving the product you use for verification.
- Transcript requests with tracked status
- Public records search
- Results attach to the same payee or employee record
How it works
Why teams switch
TINCheck and Compliancely both do real-time and bulk TIN matching, and both layer on sanctions/watchlist screening. The gap is what happens after a check passes: with Plain Dot | Check, a verified TIN flows straight into a Plain Dot | Tax filing with no export/import step, because it's the same account and the same bill.
