EIN (Employer Identification Number)
The nine-digit number that uniquely identifies a US organization to the IRS.
An Employer Identification Number, or EIN, is the nine-digit identifier the IRS assigns to an organization. It is the stable key that links a nonprofit to its filings, so grants can be reconciled between a funder's return and a recipient's return.
Matching grants by EIN, rather than by name, is what lets the co-funder graph connect a foundation to the organizations it funds.
