Effective October 1, 2020, only the Arizona Travel ID (driver license or ID card), a U.S. passport and other federally approved identification will be accepted at TSA airport security 
checkpoints for domestic travel. Note: Rules for international travel are unchanged, and a valid passport or equivalent will be required to travel outside the United States.
The Arizona Travel ID is the credential that complies with the federal REAL ID Act of 2005. It is available as both a driver’s license and identification card. There is a gold star embedded in the card to show that the cardholder has provided added proof of identification to ensure the license or ID meets strict federal requirements.
What does this mean? Your regular state driver’s license may be good for typical situations when you need to show ID, like buying liquor or establishing a bank account — and driving.
Steps for Obtaining a REAL ID
Getting a REAL ID is more complex and time-consuming than a regular driver’s license. You have to show up at a DMV office in person and bring proof of identity, proof of Social Security number (or confirmation you are ineligible for one), proof of date of birth, proof of citizenship (or other legal status) and proof of state residency.
For some people, this may be a problem. Sometimes proof of residency documents are in a spouse’s name. Maybe your address is a P.O. box, which is not sufficient as proof of residency. For those that do not want a REAL ID driver’s license: A current U.S. passport serves the same purpose as a REAL ID for federal purposes. If you still have your old driver’s license as of October 1, 2020, you can still use your current U.S. passport at the airport, whether it is for domestic or foreign travel. Passports are good for 10 years and can be renewed by mail if you are not in a rush.
