Confirming EIN and Receipt of Your SS-4 Form
After submitting your request, confirm your EIN and ensure you receive your documentation. The IRS will send the requested verification to the destination arranged during your call. If you used the online application originally, compare the EIN on your saved CP 575 or new 147C with your other official business documents. If there are discrepancies, contact the IRS Business and Specialty Tax Line and provide supporting documentation to resolve issues. Ensure the business name and address on the document match your current records to avoid complications.
