If you still don’t have a REAL ID, the deadline set by the U.S. Department of Homeland Security is Oct. 1, 2021.
The REAL ID is a driver’s license or state ID that is compliant with the REAL ID Act passed by Congress in 2005. The ID will be needed to fly domestically or visit military or other secure federal facilities.
You will need to visit a Secretary of State Driver Services Facility and provide several forms of acceptable documentation:
A document identifying yourself. Acceptable documents include a birth certificate, U.S. passport, Consular Report of Birth Abroad from the U.S. Department of State, a certificate of citizenship from the U.S. Department of Homeland Security, certificate of a naturalization, employment authorization document, or a foreign passport with a valid U.S. visa.
Proof of your Social Security number. This can be in the form of a Social Security card or a W-2 or pay stub with the full number on it.
Provide two current residency documents that includes your full name. This could include a bank statement or canceled check dated within 90 days; a credit card statement; a school report card or certified transcript; a credit report from within the past 12 months; deed/title, mortgage or rental/lease agreement; insurance policy; medical claim or statement from a private or public insurance company dated within 90 days; pay stub; official mail from federal, state or county government; pension or retirement statement; official mail from a college or university within the past year; utility bill within past 90 days; or a voter registration card.
Proof of signature. Provide a credit/debit card, canceled check or current ID with your signature on it.
The driver’s facility will give you a temporary paper ID when you leave. Watch your mail for your new ID to arrive within 15 business days.
