In order to complete USPS Form 1583, you are required to submit 2 forms of identification. At least one of those must be a photo ID.
Valid forms of photo identification include a passport, driver’s license or state issued identification card, government issued IDs, a military ID, or alien registration card.
If you only have one of these and need a second form of identification, you can also submit your current apartment lease or mortgage bill, vehicle registration card, medical bill, or insurance policy.
