# TIN Verification API Route

> Jun 3, 2025

A new standalone `POST /tin_verifications` route is now available.

This allows customers to run IRS TIN checks, for both EINs and SSNs, without submitting a full Business Search.

You can access this standalone API route [here](https://docs.baselayer.com/api-reference/tin-verification/submit-tin-verification.md).
