The Transmitter Control Code (TCC) is assigned by the IRS and consists of 5 characters. This code is assigned by the IRS once form 4419 has been approved. This code comes to you in the approval letter from the IRS. It is used to identify payers/transmitters and to track their files through processing. If you file for multiple payers simply submit for 4419 once and use the same TCC for all files you generate. You can not use more than one TCC in a file.
