You are not legally required to provide your SSN to businesses or other entities, however, their policies may impact whether they choose to work with you.
So unfortunately... they will decline to do business with you if you decline to provide your SSN.
The only logical solution: Government needs to mandate a no SSN requirement and make it illegal to refuse service even if no SSN is provided.
