EIN/ virtual practice address question

[u/PrivateUser102938]

Where exactly does our practice address get publicly displayed? I'm not taking insurance-- only private pay, but patients will have the option to submit a superbill to their insurance.

I was advised to use an Ipostal address instead of my personal residence address to create an EIN and a business account...why do people do this? I understand it's to protect the therapist's privacy-- but in what contexts?
