When you register to obtain an FCC Registration Number (FRN), you will need to provide your TIN, or taxpayer identification number. A TIN is a nine-digit number that the Internal Revenue Service (IRS) requires of all individuals, businesses, and other employers to identify their tax accounts with the IRS. The Debt Collection Improvement Act of 1996 (DCIA) enacted by Congress requires the FCC to collect this information to improve collection of delinquent government debts.
