Most international travelers know by now that it’s unwise to head to the airport with a passport that expires in less than 6 months. Egypt, Singapore, Thailand, and Fiji are just some of the countries that will refuse entry to visitors who fall afoul of that rule. (For the record, there are countries where the 6-month validity requirement doesn't apply.)

But the expiration date is far from the only detail on a seemingly valid passport that can get its owner turned away by border agents. Here are seven more lesser-known reasons an up-to-date passport can be refused.

Reason for rejection #1: Your passport doesn’t have enough blank pages.

“One of the biggest issues for those lucky, regular long-haul travelers is simply running out of space,” says Kate Scott, worldwide specialist at The Luxury Holiday Company. “Many countries in Africa, Asia, and the Middle East require between two and four blank pages for visas and entry stamps. Without them, you can be stopped from flying, even with a valid passport.”

Keep in mind that some countries use oversized stamps and stickers that take up tons of space, and trips with complex itineraries involving multiple stops across several countries will fill up pages even faster.

To find out the passport requirements for the destination you plan to visit, go to that country’s page at the U.S. State Department’s travel website and scroll to the section on passport requirements. That’s where you’ll find how many blank pages need to be in your passport, as well as how long your passport needs to be valid at the time of travel.

Reason for rejection #2: The name on your passport doesn’t match your boarding pass.

It’s distressingly easy to find yourself in a whole world of travel trouble simply because your passport doesn’t include your middle name but your flight booking does. Similarly, you could run into hurdles if your boarding pass uses a shortened or outdated form of your name (after changing it, for example), while your passport differs.

“One common issue is name discrepancies,” says Kristin M. Lamoureux, collegiate associate professor of hospitality and tourism management at Virginia Tech University. “For example, if the name on your passport is incorrect, or you recently changed names and didn’t go through the proper channels to alert the authorities.”

It’s also worth looking into any restrictions you might face if you have a passport with a gender-X or other nonbinary indicator. Some countries will only accept M or F gender markers.

Trans and nonbinary travelers should contact the airline or a travel advisor to confirm that their passports will be accepted by both the carrier and the destination. (The U.S. no longer issues gender-X passports but still accepts them for outbound and inbound travel.)

Reason for rejection #3: You owe the government a lot of money.

Have you racked up debt in the form of a large tax bill or lagging child support payments? Your passport could end up getting canceled.

Obviously, legal authorities will notify you if that happens. But even after you settle any significant outstanding debts, you’ll want to double-check to make sure that any restrictions on your passport have been reversed before trying to travel internationally.

“Your passport can be revoked for certain financial or legal reasons,” explains Lamoureux. “Some examples may include owing outstanding child support or significant tax debt. Additionally, in some cases having an outstanding warrant or certain types of court-ordered travel restrictions may result in your passport being revoked.”

Bear in mind that we’re talking about significant amounts of debt here, not simply a missed student loan payment.

Passport revocations due to tax debt can only occur in the event of what the IRS calls “seriously delinquent tax debts” totaling more than $66,000. For child support, owing more than $2,500 makes you ineligible for a passport.

Reason for rejection #4: Your passport has undergone minor wear and tear.

Rips, stains, water damage, creases, and bending can all result in your passport getting rejected by border officials.

In some cases, the damage doesn’t even have to be all that serious. In the same way certain airlines now offer airport staff financial benefits for spotting passengers with overweight baggage and squeezing them for additional fees, border officials in some countries have never been more likely to reject passports due to minor wear and tear—and there’s a reason.

“Airlines now face massive fines—often exceeding $5,700 per passenger—for boarding travelers with damaged documents,” says New York University Professor Anna Abelson of the Tisch Center of Hospitality. “To protect their bottom line, gate agents are trained to reject passengers for frayed edges or souvenir stamps. Destinations like Thailand and Vietnam are notoriously strict.”

Reason for rejection #5: Your passport has sustained damage you can’t even see.

The growing prevalence of biometric checks at airports (involving data such as fingerprints and face scans) is another reason to guard your passport carefully.

“Border control has shifted from human discretion to high-precision biometric sensors,” says Abelson. “Automated gates, such as Europe’s Entry/Exit System (EES), utilize high-resolution infrared scans. Even a minor water ripple or a tiny tear can be flagged as counterfeit because it disrupts the sensor’s light path. Additionally, if you’ve been pocket-carrying or excessively bending your passport, you could easily have snapped the internal connection of the RFID antenna which all modern passports have, rendering the chip unreadable.”

Reason for rejection #6: You’ve acquired novelty passport stamps.

When it comes to souvenir passport stamps, our advice is to steer clear.

Backpacking around Japan? Yes, those beautiful hanko stamps—which you’ll see everywhere from gas stations to museums—are lovely. Likewise for the sought-after novelty passport stamps offered at Checkpoint Charlie in Berlin.

But adorn your passport with these souvenirs at your peril. A growing number of countries will refuse entry to travelers with novelty stamps in passports, regarding the decorations in the same way they’d treat a rip or stain.

Reason for rejection #7: You catch a passport agent on a bad day.

The minuscule smudge of dirt on your passport’s photo page might be ignored by one border agent but deemed unacceptable by another. That’s precisely why you should treat your passport with extreme care—now more than ever.

“Every border agent has a wide latitude when it comes to deciding whether a passport is acceptable or not,” says Professor Wayne W. Smith, director of the Institute for Hospitality & Tourism Research at Toronto Metropolitan University.

In other words? Keep your passport as immaculate as possible and be polite. Don’t tempt fate by giving that grumpy border official a reason to ruin your vacation.

For help determining whether you should replace your passport even if it hasn’t expired yet, the State Department’s travel website contains a wealth of information on destinations’ validity windows and blank-page requirements, as well as regulations on name-change procedures, signs of damage, and other important considerations.
