Does this mean that entering a T4 Transmitter number is optional? Can we file paper copies and not internet copies still? Edit: have done some further reading and see it is an assigned number. Any advice where the number can be found? I have not found that information on the gov't link shared. Thanks for any help you can provide.

The transmitter number is not optional. All business are required to file online. You should have gotten a letter with your access code.

~~ I don't know how Online works, this is from doing it on Desktop<>

IF you have a CRA 'Access Code' 

• Use: 000000 as the transmitter number
• When you get to the CRA T4 submittal site it will ask you for your business # (that is the full # with the RP*****
• then put in your 'access code'
