What is a business name control code?

The IRS uses business name control codes to verify that the identifying information provided on tax returns and forms corresponds to the correct company. A business' name control code is made up of alphanumeric characters (plus hyphens and ampersands) and is usually the first four characters of the business' name.

The business name control code and Employer Identification Number (EIN) on electronically filed returns must match the ones on record with the IRS, or the return will be rejected as incorrect.
