Binance and giving them a SSN

[gristlelump]

I tried to open an account on Binance in order to transfer coins off Poloniex.  Obviously they need a U.S. SSN.  I wanted to see if I could do it without giving them my actual SSN and entered it in one digit off at the end XXX-XX-XXX?.  The attempt failed and they wouldn't establish an account.  I received a message that stated that the SSN entered did not match my name entered.  My question is how the hell do they know my name and SSN do not match?

Probably using the SSN verification service. I wouldn't suggest using fake information even if they didn't have an automatic system to verify these data, as you risk getting your account blocked in the future.
