How to address the envelope

  1. Use the address letter for letter

    Copy 111 Congress Avenue, Suite 500, Austin, TX 78701 letter for letter. A wrong digit in 78701 is enough to send the letter on a detour.

  2. Put your own address on it

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Send it by certified mail

    Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Austin is traceable from the article number until it is signed for.

  4. File the receipt with your copy

    Your copy of the letter, the mailing receipt and the tracking record belong together in one file.
