EIN only business bank account without ss#

[Tod Foltyn]

Hi everyone, can someone help answer this question for me? I have a holding company LLC which is 100% owner of my subsidiary LLC. So my understanding is not 100% clear. So when it is said that you can open a business bank account for the subsidiary LLC with EIN only and without ss# does this mean with NO ss# at all whatsoever? Or does this just mean the account uses the EIN to only open up the account BUT you still need to give your ss# to be on the account to have access and be a signer??

Any time I have seen this question the answer has not been 100% clear. Hopefully someone can clarify for me. 

So let me know if there is anyway to NOT use my ss# at all whatsoever, OR do I still need to use it but ONLY to have access and be a signer BUT NOT to open the account up. 

Hopefully this makes sense! Thank you in advance for any clarification, greatly appreciated!
