You can use your green card as an ID in most situations where a federal document is accepted: boarding domestic flights, completing new-hire paperwork, opening a bank account, applying for a Social Security number, and re-entering the United States after a trip abroad. It won’t replace a state driver’s license for state-level purposes, and it never proves U.S. citizenship. Federal law also requires every permanent resident 18 or older to carry the card at all times.1GovInfo. 8 USC 1304 – Forms for Registration and Fingerprinting
Boarding a Domestic Flight
TSA accepts the permanent resident card as identification at airport checkpoints.2Transportation Security Administration. Acceptable Identification at the TSA Checkpoint You don’t need a passport or a driver’s license if you have your green card with you.
REAL ID enforcement began on May 7, 2025, but it doesn’t change anything for green card holders. REAL ID rules apply to state-issued driver’s licenses and ID cards, not federal documents.3Transportation Security Administration. REAL ID If your state license is noncompliant, your green card is a straightforward alternative at the checkpoint.
Starting a New Job
When you’re hired, your employer has to verify both your identity and your authorization to work using Form I-9, a requirement that traces back to the Immigration Reform and Control Act of 1986.4U.S. Citizenship and Immigration Services. Handbook for Employers M-274 – 1.0 Why Employers Must Verify Employment Authorization and Identity of New Employees The green card is one of the few documents that satisfies both in a single step. Most other combinations require two documents, like a driver’s license paired with a Social Security card.
Some jobs go further. Positions requiring security clearances or professional licenses often ask for a passport or state ID on top of what Form I-9 requires.
Banks, Credit, and Social Security
Financial institutions must verify your identity before opening an account. Section 326 of the USA PATRIOT Act sets the minimum procedures, and a green card meets them.5FinCEN. USA PATRIOT Act You can generally use it to open a bank account, apply for a credit card, or take out a mortgage.
The Social Security Administration also accepts the card as proof of both immigration status and identity when you apply for a Social Security number or replace a lost card.6Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card Bring the original, unexpired card. Photocopies and notarized copies aren’t accepted.
Coming Back Into the United States
A valid green card is enough to re-enter the U.S. at a land border, sea port, or airport. Customs and Border Protection confirms that lawful permanent residents don’t need a passport to come home; a valid green card or re-entry permit is sufficient.7U.S. Customs and Border Protection. Documents Needed for Lawful Permanent Residents (LPR)/Green Card Holders
The card won’t get you into another country, though. Foreign border officers want a passport from your country of citizenship, and often a visa. Your green card proves U.S. residency, not citizenship. Carry both when you travel.
Length of trip matters, too. If you stay abroad more than one year, your green card alone is no longer sufficient for re-entry. Before a long trip, apply for a re-entry permit using Form I-131 through USCIS.8U.S. Customs and Border Protection. Can a U.S. Lawful Permanent Resident Leave the United States? Re-entry permits are generally valid for two years. Without one, you risk being denied entry and losing your permanent resident status.
Where a Green Card Isn’t Enough
State-level activities usually require a state-issued ID. Getting a driver’s license, buying alcohol, and accessing certain state government services typically call for a state driver’s license or ID card. Most states will accept your green card as one of the documents needed to obtain that state ID, but it doesn’t replace one.
Voting Is Off-Limits
A green card proves legal residence, not citizenship, and only citizens can vote in federal elections. Voting as a noncitizen is a federal crime punishable by up to one year in prison.9Office of the Law Revision Counsel. 18 USC 611 – Voting by Aliens Voting unlawfully can also make you deportable, and that determination doesn’t require a criminal conviction.10Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens If a motor voter system registered you by mistake, get it corrected before any election rather than casting a ballot.
Carry It Every Day
Federal law requires every permanent resident age 18 or older to carry the green card at all times. Failing to have it on you is a misdemeanor, punishable by a fine of up to $100, up to 30 days in jail, or both.1GovInfo. 8 USC 1304 – Forms for Registration and Fingerprinting Enforcement in everyday life is uncommon, but the rule exists. Keep the card in your wallet the way you’d keep a driver’s license.
When the Card Expires
A standard green card is valid for 10 years. Conditional permanent residence, typically granted through a marriage that was less than two years old at approval, produces a card valid for two years.11U.S. Citizenship and Immigration Services. Conditional Permanent Residence Expiration doesn’t end your status, but it does create practical problems. TSA requires valid identification, and an expired card may not qualify. Banks and employers may also refuse it.
USCIS recommends filing Form I-90 to renew when your card will expire within six months.12U.S. Citizenship and Immigration Services. Replace Your Green Card The receipt notice you get after filing acts as temporary proof of status when presented with your expired card and extends its usefulness for 36 months past the expiration date. If your card is lost or stolen, USCIS can issue an ADIT stamp in your foreign passport as temporary evidence of permanent residence while you wait for a replacement.
Misuse Has Serious Consequences
Using a green card fraudulently carries severe federal penalties. Forging or knowingly using a fraudulent immigration document can result in up to 10 years in prison for a first or second offense, with longer sentences for repeat offenses or when the fraud is tied to drug trafficking or terrorism.13Office of the Law Revision Counsel. 18 USC 1546 – Fraud and Misuse of Visas, Permits, and Other Documents Presenting a green card as proof of citizenship falls into this territory.
Lending or selling your card to someone else is a separate federal offense. Transferring an identification document for unauthorized use carries up to five years in prison.14Office of the Law Revision Counsel. 18 USC 1028 – Fraud and Related Activity in Connection with Identification Documents, Authentication Features, and Information
Beyond criminal penalties, any document fraud can trigger deportation. A permanent resident subject to a final order for document fraud becomes deportable.10Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens Use the card only for its intended purpose, and never let anyone else use it.
