Three numbers, three agencies
Asking for the wrong number is a common reason a search comes back empty.
| Number | Issued by | What it identifies |
|---|---|---|
| Federal EIN | Internal Revenue Service | Identifies the business for federal tax. It is the same number in every state. |
| Identification Number (ID Number) | Secretary of the Commonwealth, Corporations Division | Identifies the entity's record in the state registry. 9 digits. Many entities carry a state-assigned number with leading zeros, for example 000924901; others carry their federal EIN as the ID Number, with the earlier state number shown as Old ID Number |
| Massachusetts DOR business tax account (MassTaxConnect) | Massachusetts Department of Revenue | The Corporations Division asks for the federal EIN on formation filings and, for many entities, uses it as the public ID Number. Entities without one carry a state-assigned 9-digit number starting 000. DOR tax accounts are separate and managed in MassTaxConnect. |
