Employer Identification Numbers (EIN) are a unique Federal ID assigned to each registered business entity. An EIN should be matched against a legal entity name as a baseline business verification process.

TIN Review Tasks
To make decisioning easier off the above TIN data, key insights will be aggregated into review tasks that can be found on the Business payload (business.review.review_tasks).
TIN Match
This review task indicates if the TIN and name match was able to be verified with the IRS. The following JSON indicates the possible states of this task. The TIN will only be verified against the person name if that feature is enabled for your account.
{
"key": "tin",
"category": "tin",
"label": "TIN Match",
"sub_label": "Found",
"sub_key": "found",
"status": "success",
"message": "The IRS has a record for the submitted TIN and Business Name combination"
}

"sub_label": "Not Found",
"sub_key": "not_found",

"category": "tin",

"sub_label": "Error",
"sub_key": "error",
"status": "failure",
"message": "IRS unavailable"
}
TIN Issued
If the TIN fails to be verified against the Business name provided, the IRS will indicate if the TIN has been issued or not. Newly issued TINs may take several days to several weeks to be processed into the IRS' database, so if this status is received from the IRS, it could be the case that the TIN is still being processed at the IRS. This review task will be present if the IRS has indicated that the TIN is not yet issued, otherwise, it will not be present in the review tasks list.
{
"key": "tin_issued",
"category": "tin",
"label": "TIN Match",
"sub_label": "Not Issued",
"sub_key": "not_issued",
"status": "failure",
"message": "TIN has not been issued by the IRS. There is often a delay after formation for the IRS database to process TINs for new businesses."
}
Verification of EINs/SSNs against Individuals
Some small businesses like single-member LLCs have EINs that match an officer's name instead of the registered business name. To utilize this feature, we will want to ensure that you are passing in both the EIN/TIN and the individual's name. Note that this is an optional feature that can be turned on by reaching out to your Account Manager or to [email protected]
Dashboard:
If the TIN is verified using a person's name, a warning will be displayed on the TIN match card as a “Person Match."
EIN Verification JSON Response:
The Employer Identification Numbers (EIN) response now includes verified_by as an optional field. If the TIN is verified using the business name, this field will be populated with business. If the TIN is verified using the person’s name, this field will be populated with the "person."
