Florida requires a physical address, along with the Certificate of Authorization number. I would guess that most states would have the same requirement.
Even if it is not required in your state, it is good free advertising for your firm. It's also stating that you are proud of the product and willing to put your name and reputation on it.
The IBC has a 'minimum" list of info that needs to be provided. Our local code enforcement requires the PE's address and phone number. They often call with questions or comments - some stupid - some good.
