A U.S. passport can stop working as a travel document for a long list of reasons, and expiration is only the most obvious one. What makes a passport invalid ranges from physical damage and unauthorized alterations, to a lost-or-stolen report you filed and later regretted, to a name that no longer matches your other identification, to federal action taken against you for unpaid taxes, child support arrears, an outstanding felony warrant, or a drug trafficking conviction. Adult passports are valid for ten years and passports issued to anyone under 16 expire after five, but the real problems usually start well before the printed expiration date.
Expiration and the Six-Month Rule
Once your passport reaches its printed expiration date, it is no longer a valid travel document. It can also become unusable months earlier because of entry rules imposed by your destination.
Many countries enforce what travelers call the six-month rule, requiring your passport to remain valid for at least six months beyond your date of entry or departure. The State Department warns directly that “some destinations will not let you enter if your passport will expire within 6 months.”1U.S. Department of State. Age 65+ Travelers The United States applies the same standard to foreign visitors.2U.S. Customs and Border Protection. Countries That Extend Passport Validity for an Additional Six Months After Expiration The Schengen Area, covering most of Western and Central Europe, requires at least three months of validity beyond your planned departure from the zone.3U.S. Embassy & Consulates in France.

If your passport falls short of the destination’s rule, the airline can refuse to board you before you ever leave home. Check your destination’s specific requirement before booking, and renew early if you are anywhere close to the cutoff.
Physical Damage
A damaged passport is not valid for travel, and the bar for “damaged” is lower than most people expect. The State Department says you need to replace your passport if it has any of the following:4U.S. Department of State. Frequently Asked Questions About Passport Services
- Water damage, including mold and stains
- A significant tear
- Unofficial markings on the data page
- Missing visa pages that have been torn out, ripped, or cut
- A hole punch
Normal wear does not count. A slight bend from your back pocket, or visa pages that fan out from frequent use, does not require a replacement.4U.S. Department of State. Frequently Asked Questions About Passport Services The distinction matters because border officers make judgment calls. A coffee stain on a visa page is ambiguous enough that an officer might wave you through or pull you aside. If the data page is affected, if your photo is obscured, if the machine-readable zone is unreadable, or if the embedded chip is nonfunctional, expect problems.
Any unauthorized alteration invalidates the passport immediately and creates criminal exposure. Changing personal data, swapping a photo, or tampering with stamps is a federal crime carrying up to 25 years in prison.5Office of the Law Revision Counsel. 18 U.S. Code 1543 – Forgery or False Use of Passport
Sometimes the damage comes from the government. If your passport arrives with a misspelled name, incorrect birthdate, wrong sex marker, missing data, discoloration, or crooked printing on the biographical page, do not travel on it until the error is corrected. The State Department will fix these errors at no charge using Form DS-5504.6U.S. Department of State. Name Change for U.S. Passport or Correct a Printing or Data Error
Reporting a Passport Lost or Stolen
The moment you report a passport as lost or stolen, the State Department permanently invalidates it. If you later find the book in a coat pocket, it cannot be used again.7USAGov. Lost or Stolen Passports You must apply for an entirely new passport.
Attempting to travel on a passport you previously reported invites serious problems. The State Department warns that you “may be delayed while traveling and denied entry to a foreign country.”8U.S. Department of State. Report Your Passport Lost or Stolen The invalidation is flagged in international databases and will surface at any checkpoint that scans the document. Think carefully before filing the report. Once it is in the system, there is no reversing it.
Name and Appearance Mismatches
Your passport needs to match your current legal identity. After a marriage, divorce, or court-ordered name change, a passport in your old name creates a mismatch with your airline ticket, other identification, and potentially your visa. If both the passport issuance and the name change happened within the past year, you submit Form DS-5504 with a certified document proving the change. If more than a year has passed since either event, you go through a standard renewal or new application.6U.S. Department of State. Name Change for U.S. Passport or Correct a Printing or Data Error
Physical appearance is a separate issue with a higher threshold. Growing a beard, coloring your hair, and normal aging do not require a replacement. You do need a new passport after significant facial surgery or trauma, adding or removing many large facial piercings or tattoos, or significant weight change.9U.S. Department of State. U.S. Passport Photos The test is whether a border officer can still identify you from the photo.
Government Denial and Revocation
The federal government can deny a new passport application or revoke one you already hold. The grounds are broader than most people realize.
Outstanding Warrants and Court Orders
The State Department can refuse to issue a passport if you are the subject of an outstanding federal or state felony warrant, if a court order or condition of probation or parole forbids you from leaving the country, if you have been committed to a mental institution by court order, or if a court has declared you legally incompetent.10eCFR. 22 CFR 51.60 – Denial and Restriction of Passports Pending extradition requests and certain federal grand jury subpoenas also trigger denial. These grounds are discretionary, but in practice an active felony warrant will stop an application cold.
Seriously Delinquent Tax Debt
If you owe the IRS more than $66,000 in 2026, a figure that adjusts annually for inflation, including penalties and interest, the IRS can certify your debt to the State Department, which is then required to deny your passport application or can revoke an existing passport.11IRS. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes The debt must be “seriously delinquent,” meaning the IRS has already filed a federal tax lien or issued a levy against you.12Legal Information Institute. 26 U.S. Code 7345 – Seriously Delinquent Tax Debt Definition If your passport is revoked for tax debt, the State Department may issue a limited passport that only allows you to return to the United States.13Office of the Law Revision Counsel. 22 U.S. Code 2714a – Revocation or Denial of Passport in Case of Certain Unpaid Taxes
Child Support Arrears
Owing more than $2,500 in past-due child support is a separate ground for denial. When a state child support agency certifies the debt to the Department of Health and Human Services, that certification is forwarded to the State Department, which must refuse to issue a passport and can revoke or restrict an existing one.14Office of the Law Revision Counsel. 42 U.S. Code 652 – Duties of Secretary Unlike the tax rule, this one is mandatory. The State Department “shall” refuse, not “may” refuse.
Drug Trafficking Convictions
A conviction for a federal or state drug felony where you used a passport or crossed an international border during the offense triggers automatic passport revocation. The Secretary of State is required to revoke it, not merely permitted. For drug misdemeanors, revocation is discretionary, and a first offense involving only possession of a controlled substance is excluded entirely.15Office of the Law Revision Counsel. 22 U.S. Code 2714 – Denial of Passports to Certain Convicted Drug Traffickers
Fraud and Misrepresentation
A passport obtained through fraud, misrepresentation, or material error can be revoked at any time. The same applies if the passport has been fraudulently altered or misused after issuance, or if the State Department later determines the holder is not a U.S. national.16eCFR. 22 CFR 51.62 – Revocation or Limitation of Passports
Sex Offender Registration
Under federal law, the State Department cannot issue a passport to a registered sex offender unless it contains a conspicuous visual identifier marking the holder as a covered sex offender. A passport previously issued without that marking can be revoked.17Office of the Law Revision Counsel. 22 U.S. Code 212b – Unique Passport Identifiers for Covered Sex Offenders The identifier applies to both passport books and passport cards. The passport remains technically valid with the marking, but some countries may deny entry, and the identifier cannot be removed as long as registration is required in any jurisdiction.
Two Cases That Look Like Invalidity but Aren’t
A passport card is a legitimate citizenship document, but it is not valid for international air travel. It works only for land and sea crossings between the United States and Canada, Mexico, Bermuda, and certain Caribbean countries.18U.S. Department of State. Get a Passport Card Show up at an airport with only a passport card for an international flight and you will not board. There is no workaround at the gate.
A passport with no remaining blank pages is technically still valid, but it is functionally useless for visiting countries that require space for entry stamps or visas. Most countries require at least one blank page, and many popular destinations across Africa, Asia, and Europe require two or more. Airlines check for this before boarding because they face penalties for delivering passengers who will be turned away at the destination.
