The World’s Leading Tax Identity Infrastructure TIN Validation, Entity Verification & Identity Intelligence
One infrastructure layer for identity. Real-time TIN validation against official sources, entity verification through 120+ business registries, and multi-signal intelligence including document validation, watchlist screening, and adverse media.
TIN validation, entity verification, and identity intelligence — each available independently or as a unified identity layer for your compliance workflows.
Real-time TIN lookup against official government registries for 130+ countries. Format, structure, and check-digit validation for 1,000+ TIN types across 210+ countries. Every validation produces audit-ready evidence with timestamp, source, and result.
Verify legal entities directly against 120+ official company registries worldwide. Returns entity name, registration number, legal form, incorporation date, active status, and registered address — from the authoritative government source.
Multi-signal identity verification beyond TIN and entity data. Tax and business document validation, address verification against postal databases, AML and watchlist screening across 290+ official databases, adverse media monitoring, and digital signal checks.
Financial institutions, enterprises, platforms, and tax teams — each with different regulatory drivers, all requiring the same identity infrastructure.
CRS, DAC8, FATCA, and CARF mandate validated TINs at account onboarding. Tax Identity delivers real-time TIN validation and entity verification at the point of due diligence — before the account is opened, not months after.
Client and vendor onboarding requires verified tax identity for KYC, e-invoicing, and withholding. Tax Identity validates TINs and entity status in real time during onboarding workflows — eliminating manual registry lookups and follow-up cycles.
DAC7 requires platforms to verify seller identity and tax residency before reporting. Tax Identity validates seller TINs and business registrations at sign-up, producing the evidence trail that DAC7 due diligence demands.
Reverse charge VAT exemptions require a valid counterparty TIN. E-invoicing mandates demand verified tax IDs on every transaction. Tax Identity validates TINs at the transaction level for tax determination and exemption proof.
Tax Identity operates independently — but when other TaxDo engines need identity data, they call Tax Identity natively. No duplicate integrations. No conflicting results.
When Regulatory Compliance processes a CRS or DAC8 due diligence event, TINs are already validated through Tax Identity. No separate validation step. No remediation backlog from invalid TINs discovered at reporting time.
Indirect Tax validates counterparty TINs through Tax Identity for reverse charge exemptions and e-invoicing mandates. One source of truth for tax ID validity across both compliance domains.
Tax Identity, Indirect Tax, and Regulatory Compliance each operate as standalone engines. The shared layer is additive — it eliminates re-work when you use multiple engines, but no engine depends on another to function.
Every coverage number reflects live, maintained connections — not static databases or theoretical reach.
Official government registries. Live confirmation that a TIN is issued and active.
Offline format, structure & check-digit validation for 1,000+ TIN types — instant, no registry call.
Official company registries. Entity name, status, legal form, and registration data.
Government sanctions lists, PEP databases, and regulatory enforcement records.
Most of what is sold as tax ID validation stops at format checking. We go four layers deep, and each one answers a question the layer before it cannot.
Is the TIN Well Formed?
Format and checksum rules for 1,000 tax types, built against each jurisdiction's own guidelines. Most providers stop here.
Is the TIN Real and Active?
A live query to the tax authority itself. No intermediary databases, no cached copies. Returns holder, type and status.
Does the Registry Match The Tax Record?
The tax authority record matched field by field against the official business registry. Two sources that disagree is the first red flag.
Is The Business Behind The TIN Real?
Tax residency triangulated, digital footprint investigated, tax documents read forensically. One verdict across eight areas and 30+ signals.
REST APIs, webhook-driven events, batch processing, and real-time modes — every identity capability is available programmatically with enterprise-grade SLAs.

A Tax Identification Number (TIN) is a unique identifier assigned by a government authority to individuals and entities for tax administration. Every country has its own TIN format and issuing authority — the US uses SSN and EIN, the UK uses UTR and NI numbers, Germany uses the Steuerliche Identifikationsnummer. Under CRS, DAC8, FATCA, and CARF, financial institutions must collect and validate TINs for every reportable account holder.
TaxDo validates TINs through a multi-tier approach. For 130+ countries, TaxDo performs real-time lookup against official government registries — confirming the TIN is issued and active. For countries without real-time API access, TaxDo applies format and syntax validation against 1,000+ known TIN types across 210+ countries, verifying structure, check-digit algorithms, and country-specific rules. Every validation produces an audit-ready evidence record.
A business registry check verifies that a legal entity exists and is active by querying official company registries maintained by government authorities. TaxDo connects to 120+ official registries worldwide, returning entity name, registration number, legal form, incorporation date, active status, and registered address. This is essential for entity due diligence under CRS, DAC8, and anti-money laundering regulations.
CRS, DAC8, and FATCA require financial institutions to collect valid TINs at account onboarding. DAC8 also requires crypto-asset service providers to stop users who have not provided the required information from making reportable transactions, after two reminders and at least 60 days. Validating TINs in real time at the point of onboarding prevents account-blocking scenarios, reduces downstream remediation costs, and produces the audit evidence that regulators expect during examinations.
TaxDo’s Verify+ layer checks multiple signal categories: tax and business document validation, address verification against postal and government databases, AML and watchlist screening across 290+ official databases, adverse media monitoring, and digital signal validation including IP geolocation and phone number verification. Each signal is weighted according to a tiered trust hierarchy that prioritizes government-authoritative sources.
Yes. TaxDo’s TIN validation is built specifically for CRS, DAC8, CARF, and FATCA. The engine validates TINs against the exact format, structure, and check-digit rules required by each framework. For jurisdictions with real-time government API access, TaxDo confirms the TIN is issued and active — producing the audit evidence that regulators expect during examinations.
TaxDo is purpose-built for tax identity — TIN validation, entity verification, and tax-specific intelligence signals. It complements general KYC/AML providers by adding the tax layer they typically lack: government-registry TIN lookup, tax residency indicators, and compliance-framework-specific validation logic for CRS, DAC8, CARF, and FATCA. You can run TaxDo alongside your existing KYC stack.
Upload a file of account holder records and TaxDo validates every TIN against the appropriate government registry or syntax rule set. You receive a downloadable result file with validation status, match confidence, failure reasons, and audit evidence for each record. Batch processing supports onboarding backlogs, periodic re-validation, and year-end compliance preparation.
Tax Identity is one of three engines in the TaxDo OS. Each works independently — together, they eliminate the gaps between identity, tax, and transparency.
130+ countries. 1,000+ TIN types. 120+ business registries. 290+ watchlist databases. One API call away from audit-ready tax identity.
