AFAIK, for now only Bittrex. You only can withdraw your money ONCE you have verified your account (you need to do KYC).
Poloniex, binance, cryptopia, coinexchange, liqui doesn't need KYC unless you want to withdraw huge money.
Last time I checked, Poloniex required kyc before you could even trade, not just withdrawing. You could register your account but you couldn't really do anything else until you verify your info. Same with coinbase.
are you sure? because I've never used poloniex anymore, I prefer to use binance, its high volume and user is not required to verify KYC
and I think bittrex also has a complicated KYC system. I do not like that
