Comprehensive Validation Solutions
Every Validation Your Compliance Program Needs — In One Platform
Vendor compliance requires more than IRS TIN matching. It requires sanctions screening on every counterparty, W-9 collection that closes the loop with IRS validation, EIN lookup when a mismatch needs a reference point, address validation before B-Notice outreach, and audit documentation that exists before a penalty arrives. Running those checks across separate tools creates gaps — vendors screened in one system but not another, documentation scattered across platforms, correction workflows that require manual coordination between tools. TIN Comply runs all of it in one place, on every validation, with a single audit trail.
The Problem With Point Solutions
Most compliance programs are built from point solutions — one tool for TIN matching, another for sanctions screening, manual W-9 collection in email, audit documentation in spreadsheets. Each tool works independently. None of them talk to each other.
The result: a vendor passes TIN matching but was never screened for sanctions because the screening step isn't embedded in the onboarding workflow. A mismatch is returned but no correction outreach fires because that's handled manually by a different team. A corrected W-9 comes in but nobody revalidates it against IRS records. The audit documentation that would support 972CG abatement exists in three different places and has to be manually assembled under deadline.
TIN Comply's validation suite runs as an integrated workflow — TIN matching and sanctions screening in a single call, mismatches triggering W-9 outreach automatically, corrected submissions revalidating without manual intervention, every step logged to a per-vendor record that's retrievable the moment it's needed.
The Full Validation Suite
IRS TIN/Name Matching
Official IRS TIN matching — real-time results with specific result codes, not pass/fail. Name mismatch, wrong TIN type, invalid TIN, confirmed SSN match, confirmed EIN match. Every call logged per vendor with timestamp. Mismatches trigger automated W-9 correction outreach.
Sanctions & OFAC Screening
250+ global lists — OFAC SDN, OFAC Consolidated, FinCEN, BIS Denied Persons, BIS Entity List, EU Consolidated, UN Security Council, and industry-specific lists — screened automatically alongside every TIN matching call. Fuzzy matching and alias detection included. One call, complete result.
W-9 Collection & Validation
Guided electronic W-9 portal with field-level instructions, e-signature, and centralized storage. Mismatches trigger automated correction outreach — specific issue detail per vendor, not generic notices. Corrected W-9s revalidate automatically. Every step documented with timestamps.
EIN & Company Lookup
Look up the entity name associated with any EIN in our database, or find the EIN associated with a company name. A fast reference point when TIN matching returns a mismatch and you need to know what name to ask the vendor to confirm — rather than sending a generic correction request that produces low response rates.
Bulk File Processing
Validate your entire vendor population in a single pass — any file format, unlimited records, results within the hour, automatic duplicate deduplication to prevent IRS lockouts. Categorized exception report with automated outreach ready to launch. Q4 pre-filing, post-migration cleanup, M&A due diligence.
Address Validation
Validate and standardize vendor addresses against USPS guidelines before B-Notice outreach — confirming deliverability before correction requests go out. Undeliverable B-Notices create compliance gaps that are difficult to document. Address validation before outreach closes that gap.
FATCA GIIN Validation
Validate FATCA Foreign Financial Institution GIIN numbers against IRS records — confirming FFI registration status for withholding agents and qualified intermediaries with chapter 3 and chapter 4 reporting obligations.
Legal Entity Identifier (LEI) Validation
Verify Legal Entity Identifiers for global financial entities against official GLEIF data in real time — supporting transparency and compliance requirements in financial transactions, derivatives reporting, and regulatory filings that require LEI verification.
Reporting & Audit Trails
Every validation, screening result, outreach send, correction, and revalidation logged per vendor with timestamps — automatically. The documentation that supports 972CG reasonable cause abatement, CP2100 B-Notice response, and OFAC enforcement defense exists before it's needed, not assembled retroactively under deadline.
API Integration
REST API embeds the full validation suite into ERP onboarding workflows, payment authorization systems, and marketplace seller registration flows — validation at the point of data entry, before bad data is written to the vendor master. Multiple API keys, full audit logging per call, same-day onboarding.
How the Suite Works Together
The value of running all validations in one platform isn't just convenience — it's that the tools reinforce each other in ways that point solutions can't.
| Scenario | How the Suite Responds |
|---|---|
| New vendor submitted at onboarding | API call runs TIN matching + sanctions screening simultaneously — one call, complete result, full audit log |
| TIN matching returns name mismatch | EIN lookup surfaces associated name ? W-9 correction outreach fires automatically with specific correction detail |
| Corrected W-9 received | Revalidation runs automatically ? record updates only on confirmed match ? correction documented with timestamp |
| Q4 bulk validation run | Full vendor population validated in one pass ? exception report categorized by result type ? outreach campaigns launched simultaneously |
| CP2100 arrives in spring | Per-vendor mismatch history already built ? B-Notice outreach sent within 15-business-day window ? every step documented |
| 972CG penalty received | Complete per-vendor compliance record retrieved ? abatement package assembled from existing documentation, not reconstructed |
| OFAC inquiry on vendor relationship | Timestamped screening history shows every screening event ? documents ongoing monitoring, not just point-in-time onboarding check |
Why One Platform Matters
No Gaps Between Tools
When validation steps run in separate systems, vendors fall through the gaps — screened in one tool but not triggered in another, documented in one place but not the other. A single platform means every step runs on every vendor, every time.
Single Audit Trail
Documentation assembled from multiple systems under a penalty deadline is incomplete, inconsistent, and unconvincing. A single platform means a single per-vendor record — every TIN match, screening result, outreach send, correction, and revalidation in one place, retrievable in seconds.
One Platform, Every Team
AP, Tax, Compliance, Procurement, Treasury, and IT all need access to vendor validation data — but rarely to the same tool. TIN Comply gives every team access to the same records, same audit trail, and same validation results. Unlimited users, no per-seat limits.
