Description

A Taxpayer Identification Number (TIN) is an identification number assigned by the IRS for tax administration. TIN data is available on Legal Entities and is commonly used in business verification and KYB workflows to confirm that a business is who they claim to be.

Both EINs (Employer Identification Numbers) and SSNs (Social Security Numbers) are types of TIN. All businesses that have a non-person legal structure have an EIN. Many sole proprietorships also acquire an EIN, but some may use the owner's SSN as well. See the tinType field below for the full list of TIN types. Note that we do not provide SSN to protect PII.

Data Sources

Our TIN data comes directly from authoritative government sources like SoS registrations and IRS forms.

Currently, TIN coverage is approximately 4.5% of brands. Florida-registered businesses are overrepresented as Florida is the only state that publishes federal EIN data on its Secretary of State registrations.

Methodology

We routinely validate our data against the IRS directly to ensure data quality is maintained. Our entity resolution process further reconciles records across sources to surface the most accurate TIN for each legal entity. For absolute confidence in a specific business and EIN combination, you can submit another request with the TIN, legal name, and address as inputs to verify directly against the IRS in realtime. Below is an example:
