Tax ID Verification - Overview
Taxbit offers multiple validation workflows for user identification numbers, including IRS TIN matching, TIN format validation, VAT format validation, and VAT verification through VIES. Some of these checks validate syntax and structure, while others verify submitted information against an external authority data source.
See below for a brief description as well as a link for more details on each of these processes.

Description |
|
TIN Format Validation |
TIN Format Validation checks whether a Tax Identification Number (TIN) matches the expected format for the selected jurisdiction. This is a syntax check for character count, character type, and overall structure based on jurisdiction-specific rules. For more details, please refer to this article: TIN Format Validation |
|
IRS US TIN Matching |
Users with a US TIN are checked directly against the IRS database. This is the same database the IRS uses to identify instances where a B-Notice is required (e.g., 1099 filed with a Name/TIN combination that does not match the database). For more details, please refer to this article: IRS US TIN Matching |
|
VAT Format Validation |
VAT Format Validation checks whether a VAT number matches the expected format for the selected jurisdiction. This is a syntax check for character count, character type, and overall structure based on jurisdiction-specific rules. For more details, please refer to this article: VAT Format Validation |
|
VAT Verification via VIES |
VAT Verification via VIES checks a VAT number and VAT country against national VAT databases through the European Commission’s VIES system when sufficient information is available. For more details, please refer to this article: VAT Verification via VIES |
