Most travelers consider a passport card as something only needed for occasional trips to Canada or Mexico. But here’s the surprise: this little wallet-sized ID can do so much more than that.
At U.S. Passport Service Guide, we’ve been helping Americans navigate the passport process since 2002. Over the years, we’ve heard from thousands of travelers who use their passport cards in clever, unexpected ways. After sharing a recent video on this topic, some of the most popular comments came from people sharing how they use their passport cards on a day-to-day basis.
If you’re wondering whether a passport card is worth the extra $30 when you apply for or renew your passport book, here are some benefits that might change your mind.
Let’s take a look at the lesser-known uses of the U.S. passport card, how it compares to other forms of identification, and why it may be worth adding to your travel documents.

9 Clever Ways to Use a U.S. Passport Card
Based on the feedback from American travelers, here are some of the most surprising and smart uses for a US passport card:
1. A Built-In REAL ID Alternative
Since May 7, 2025, every traveler age 18 or older is required to carry a REAL ID–ID-compliant credential to board domestic flights. While upgrading your driver’s license is an option, many states still have limited DMV appointments and long wait times.
A passport card is a federally issued ID that meets REAL ID standards. You can use it at:
- TSA airport checkpoints for domestic flights
- Federal buildings
- Certain secure facilities, like nuclear plants or military bases (for civilians without DoD-issued IDs—more on that below).
2. Slim, Durable, and Wallet-Ready
Unlike the standard passport book, which can be bulky and easily damaged, the passport card is the size of a credit card. It’s made of sturdy plastic and slips right into your wallet, making it very convenient to carry. And, if you lose or damage it, replacing a card is cheaper than replacing a passport book.
3. A Handy Second Form of ID
Need two forms of ID to open a bank account, apply for a loan, or verify your identity somewhere? Instead of scrambling for a birth certificate or Social Security card, you can simply hand over your passport card with your driver’s license. Problem solved.
4. Easy Proof of Age (Without Sharing Your Address)
One of the most popular points our readers and viewers raised was using the passport card to prove age at concerts, bars, or clubs. Unlike a driver’s license, a passport card does not list your address. That means when a venue scans it, they can verify your age without collecting unnecessary personal information.
5. A Trusted Government-Issued ID
Because it’s a federal ID, a passport card can be used for official identification in a variety of situations, such as:
- Uploading an ID when using government websites
- Applying for certain services that require federal identification
- Providing ID if asked by law enforcement or officials
It’s a reliable backup if you don’t want to risk carrying your passport book everywhere.
6. Streamlined Employment Verification (Form I-9)
Here’s a use case many of our audience members pointed out: the Form I-9 you complete when starting a new job. Employers are required to verify both your identity and work authorization.
A U.S. passport card counts as a List A document on the I-9, which means it satisfies both requirements at once. Instead of digging up your Social Security card and driver’s license, you can simply hand over your passport card. For a lot of people, that makes onboarding much smoother.
7. A Travel-Smart Choice for Cruises & Land/Sea Crossings
If you’re planning a closed-loop cruise—one that starts and ends at the same U.S. port—or traveling to Canada, Mexico, Bermuda, or the Caribbean by land or sea, you can use a passport card. It is accepted as proof of citizenship and identity.
Many travelers carry both:
- Passport book → for international flights and re-entry to the U.S.
- Passport card → for day trips off the ship or quick border crossings.
That way, if your passport book is safely locked away on the ship and you get separated, the card in your wallet can help you get back on board and home without a major headache.
8. Useful for Civilians Accessing Military Bases
In our video, we mentioned military families, and several viewers were quick to clarify: active-duty service members and their dependents already have DoD-issued IDs for base access. That’s true. But here’s where the passport card is handy: civilians who need to enter military bases—like contractors, vendors, service providers, or extended family visiting someone on base—can often use a passport card as a REAL ID–ID-compliant alternative, which makes the passport card a smart option if your state-issued license isn’t compliant.
9. A Pro Move: Stagger Your Passport Book & Card Expiration Dates
One clever tip that came straight from a reader: don’t renew your passport card and passport book at the same time.
By staggering their expiration dates, you ensure you’ll always have at least one valid passport document in hand. That way, if you have to mail in your passport book for renewal, you still have a passport card you can use as ID—or vice versa. It’s a simple trick that can save you from stressful travel delays.
