The IRS EIN Reference Number 101 error code indicates that the IRS has no record of the Employer Identification Number (EIN) that was entered. This can happen for a number of reasons, including if the EIN was entered incorrectly or if the EIN belongs to a business that no longer exists. If you receive this error code, you should contact the IRS to verify the EIN and make sure that it is entered correctly.
