If I move do I have to change the Tax ID number of my business?

I have a small business in my apartment. I am planing to move to a bigger place. Maybe in the same building. My concern is that if I move I have to change the address of my business an therefore that would change everything else? Like the number of my business bank account, and more importantly, the Tax ID of my business?
Please help.

Absolutely not.

The only way you would have to change tax numbers would be if you move to a new state and then you would have to register in that state and they would assign you a new state number. But your federal number would remain the same.

Their are forms to report your change of address. Go to the tax site for your location & the feds and search on "change of address".

No.

absolutely not, no, never, and notta. the tax id is like your social security number.
the only way that it could advisable to ghange, and it still would not be a change but rather a NEW entetity issue is if you form an inc. or llc, form a partnership, but believe me YOU clearly need the advice of a CPA and a business attorney very soon, as you are in to deep.
just a suggestion, but why do you not have a p.o. box for your business?
why do you think your bank account number would change?
what appears on the top of the checks is for the benefit of stupid humans, the only important numbers are the dollars to be transfered and the magnetic coded routing numbers acrss the bottom.
