What documents prove U.S. citizenship for REAL ID applications?
Executive summary
States require original documents that prove identity, age and U.S. citizenship or lawful status to issue REAL ID credentials — commonly a U.S. passport, a certified U.S. birth certificate, a Certificate of Naturalization or Citizenship, or immigration documents like a permanent resident card or Employment Authorization Card (EAD) [1] [2] [3]. Individual state DMVs list local checklists and variations — for example Washington State and Illinois point explicitly to passport, birth certificate, permanent resident card or EAD as acceptable proof [3] [1].
1. What federal REAL ID requires — the baseline
The REAL ID framework requires applicants to provide proof of identity, date of birth, Social Security number and proof of U.S. citizenship or lawful status; federal guidance consistently lists a passport, birth certificate, permanent resident card, or an employment authorization card as examples of the “one document” that demonstrates name, birth date and citizenship or lawful status [2] [1]. The Department of Homeland Security set enforcement that REAL ID-compliant credentials (or another acceptable ID such as a passport) are needed for boarding domestic flights and entering certain federal facilities beginning May 7, 2025 [4] [2].
2. Common documents states cite as proof of U.S. citizenship
State DMVs and REAL ID portals repeatedly name: a valid U.S. passport or passport card; an original or certified U.S. birth certificate; a Certificate of Naturalization or Certificate of Citizenship; and, for non-citizens, documents such as a permanent resident card (“green card”) or an Employment Authorization Card (EAD/I-766) [3] [1] [5]. Connecticut’s guidance adds that Certificates of Naturalization/Citizenship may be subject to SAVE verification (Systematic Alien Verification for Entitlements) [6].
3. State-level wrinkles and checklists matter
Although federal law sets categories, each state’s DMV implements a checklist and can add operational details: Washington requires proof of Social Security number, proof of citizenship, proof of identity and residency [3]; Maine’s BMV instructs applicants to bring documents that establish identity, date of birth and proof of U.S. citizenship or lawful status and to show a clear trail for any name changes [7]. Practically, applicants must consult their state DMV checklist because acceptable secondary documents, translation requirements, and whether certified copies are required vary [7] [8].
4. Alternatives for people without traditional documents
Federal guidance and state pages note alternatives and verification processes when primary documents are unavailable. TSA and state DMVs recognize that in certain circumstances (natural disaster, loss of documents) states may accept alternate documents or rely on verification programs [4] [2]. The National Immigration Law Center explains that REAL ID implementation affects immigrants differently and highlights limited-term options and verification uncertainties for noncitizens [9].
5. Practical barriers flagged by reporting and officials
Journalistic and state filings show real-world hurdles: elections and state officials have warned that many residents lack passports, military IDs or REAL IDs that explicitly indicate citizenship; obtaining those documents can require time, travel, and fees, and would trigger training and outreach costs for state agencies [10]. This is a recurring theme in state advisories urging applicants to prepare required originals and certified copies to avoid delays [7] [1].
6. How to proceed — a practical checklist
Start with your state DMV’s REAL ID page and its checklist; expect to present at minimum an original or certified document that proves name and citizenship (U.S. passport, certified birth certificate, Certificate of Naturalization/Citizenship, or immigration documents like a green card or EAD) plus SSN proof and residency evidence [1] [3]. If your primary document is not in English, prepare a certified translation as some states require [8]. If you use a Certificate of Naturalization or Citizenship, expect electronic verification through SAVE in some states [6].
Limitations and gaps: available sources do not provide a single exhaustive, uniform national list of every acceptable document for all states; instead federal guidance sets categories and states publish specific checklists and procedural rules [2] [11]. Users must consult their state DMV for exact document lists, translation rules, certified-copy requirements and any name-change trails [7] [11].
