What is the mailing address to the IRS office in Austin, Texas?

I live in Texas and am needing to send my 8822 form (change of address) to the Austin location but do not know the address in which I should send the 8822 form to. Can someone give me the address? Thank you very much!

You can just send it to:

Internal Revenue Service
Austin, TX 73301-0023

The Zip+4 is enough for the post office to direct it, especially since it's probably just going to a PO Box.

If you plan to send it by courier and need the actual address, it's:

Internal Revenue Service
3651 S. Interregional, Hwy 35
Austin, TX 78741
