The Internal Revenue Service assigns each registered employer in the U.S. an Employer Identification Number, commonly abbreviated to EIN, for federal tax registration purposes. While the number assigned to an employer cannot be changed, the information the IRS has registered on the business for the EIN, including the business name and the business address, can be changed.
This can be done by mailing a letter on company letterhead to a designated IRS office.
Write a letter indicating which changes need to be made to the information registered with your EIN.
Include the legal name, social security number and contact info of the principal officer of a business registered under the EIN.
Include your EIN in the letter.
Print the letter on paper featuring the company letterhead of the business the EIN is registered for.
Mail the letter with an appropriate postage stamp to an IRS office. If your EIN is for a business registered in the states of Connecticut, Delaware, District of Columbia, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Vermont, Virginia, West Virginia or Wisconsin mail the letter to:
