No. 800 and 900 numbers use ANI to get the caller's number, not caller ID. The ANI information is transmitted irrespective of whether you have blocked the sending of CLID information.

CLID is subscriber->subscriber info, for general calls. ANI is switch->subscriber number, sent by the phone company. If you want your number to stay private, don't use free or premium services.
