According to Arizona House Bill 2162, 4/30/2010, the following are acceptable forms of ID:

1. An Arizona driver license issued after 1996 or an Arizona nonoperating identification license.
2. A birth certificate or delayed birth certificate issued in any state, territory or possession of the United States.
3. A United States certificate of birth abroad.
4. A United States passport.
5. A foreign passport with a United States visa.
6. An I-94 form with a photograph.
7. A United States citizenship and immigration services employment authorization document or refugee travel document.
8. A United States certificate of naturalization.
9. A United States certificate of citizenship.
10. A tribal certificate of Indian blood.
11. A tribal or bureau of Indian affairs affidavit of birth.

Only Arizona drivers licenses are valid. It's been 30 years since I've seen my birth certificate - and it was a little plaqstic card. Hell, I can't even use my military ID card. I guess I'll have to take my passport the next time I go to Phoenix.
