The Airport Guide

You know the feeling. The plane touches down, the seatbelt sign goes off, and everyone stands up at once — and then you walk into the arrivals hall and see it. A customs line that snakes past the barriers, around the corner, and out of sight. You've just spent nine hours in a metal tube, and now you're facing another hour on your feet before you can even think about baggage claim. There's a free way around most of that wait, and it takes about five minutes to set up. The mobile passport control app is U.S. Customs and Border Protection's official tool for skipping the paper form and the longest line, and if you're eligible, there's no good reason not to have it on your phone.

This isn't a paid fast-track service or a subscription. It's free, there's no interview, and it works at dozens of airports and border crossings. What it does is simple: it lets you answer the customs declaration questions on your phone, take a selfie, and walk into a dedicated lane with a QR-code receipt in hand. The officer still checks your physical passport, but the whole interaction takes a fraction of the time. Here's what it is, who can use it, where it works, and how to use it — plus how it compares with Global Entry and the mistakes that cost people the fast lane.

What the Mobile Passport Control App Is (and Who Can Use It)

Mobile Passport Control — MPC for short — is the free official app from U.S. Customs and Border Protection (CBP), available for iPhone and Android. It replaces the paper customs declaration form that used to be handed out on the plane. You answer the same inspection and declaration questions in the app and get a QR-code receipt to show the officer.

There's no interview, no background check, and no fee. You download the app, scan your passport to build a profile, and you're done. The app encrypts your passport information and photos, so the data you enter stays protected. That alone makes it a very different proposition from Global Entry, which we'll get to shortly.

So who can actually use it? Four groups are eligible:

• U.S. citizens — the largest group, and the one most travelers fall into.
• Lawful permanent residents — green card holders returning to the United States.
• Canadian B1/B2 visitors — Canadians traveling to the U.S. for business or tourism.
• Returning Visa Waiver Program travelers — visitors with an approved ESTA who are coming back under the Visa Waiver Program.

That's a wide net — but eligibility isn't the whole story, because your arrival point has to support MPC too. And one thing worth saying plainly: MPC does not replace your passport. You still show the physical document to the officer. The app is a shortcut through the paperwork and the queue, not a substitute for the passport itself.

Where the Mobile Passport Control App Works: 63 Sites and Counting

As of October 2026, the mobile passport control app is available at 63 sites. That number keeps growing, so check CBP's official Mobile Passport Control page before you fly — a site that wasn't on the list last month might be there now. Here's how the 63 break down:

• 37 U.S. international airports — the big gateways you'd expect, where the longest customs lines tend to form.
• 15 preclearance locations — including Dublin, Toronto Pearson, and Abu Dhabi Zayed, where you clear U.S. customs before you even board the plane.
• 4 seaports — for cruise passengers arriving by ship.
• 4 land border ports of entry — for travelers crossing by car or on foot.
• 3 departure locations in the U.S. Virgin Islands.

And the list is still expanding. On September 28, 2026, CBP added MPC at nearly 40 general aviation facilities — the smaller airports used by private and charter flights. Earlier, on April 20, 2026, MPC was deployed for eligible pedestrians at select land border crossings. A crossing or airport that didn't have it on your last trip might have it on your next one.

Why does the site list matter? Because if your flight diverts to an airport without MPC, you can't use it — full stop. There's no fallback. So before every international trip, take thirty seconds to check whether your arrival airport is on the list.

How to Use the Mobile Passport Control App: Step by Step

Using MPC breaks down into three phases: before the trip, in the air, and on arrival. None of them is complicated, but the timing matters — especially the window in the air. Get the steps right and the whole thing feels effortless.

Step 1: Before the trip — download and set up your profile

Download the Mobile Passport Control app from the App Store or Google Play. It's free, and it's published by U.S. Customs and Border Protection — check the developer name before you install, because copycat apps exist. Open it and scan your passport to build your traveler profile. It takes a couple of minutes at most.

One submission covers up to 12 people from the same household on one device, so a family can travel on a single phone — each person just needs their own passport scanned in.

Step 2: Up to 4 hours before landing — take your photo and answer the questions

This is the step with the clock on it. Up to four hours before landing, open the app, take a self-photo, and answer the CBP inspection and declaration questions — the same questions that used to be on the paper form. Are you bringing in food, plants, or large sums of cash? The app walks you through them one by one.

Your submission is valid for 4 hours in the air, so don't do it too early — submit six hours before landing and the receipt will have expired by the time you reach the officer. Aim for the last couple of hours of the flight. At land borders the window is 8 hours, but the same principle applies: don't submit it the night before.

Step 3: On arrival — follow the signs to the MPC lane

When you get off the plane, look for the signs pointing to the Mobile Passport Control lane. They're usually posted clearly in the arrivals hall, and the lane is separate from the regular queue — often much shorter, sometimes nearly empty. Walk up, show the officer your QR-code receipt on your phone and your physical passport, and answer any questions they have. That's it. No paper form, no long wait, no fumbling for a pen.

How much time does it save? The MPC lane is usually much shorter than the regular line — at busy hubs during peak arrival banks, the difference can be forty-five minutes or more. But it's not guaranteed to be faster every time: if three wide-body jets land at once, the dedicated lane can back up too. Even so, you're almost always better off in it than in the general queue.

Mobile Passport Control vs Global Entry: Which One Should You Get?

This is the question that comes up most often, and the honest answer is that it depends on how you travel. The two programs solve a similar problem — getting through U.S. customs faster — but they do it in very different ways, at very different prices.

Global Entry costs $120 for five years. It requires an application, a background check, and an in-person interview at an enrollment center. In return, you get expedited clearance through automated kiosks, and it includes TSA PreCheck benefits — a faster security line on the way out, too. If you fly internationally several times a year, that $120 pays for itself in saved time and reduced stress pretty quickly.

MPC, on the other hand, costs nothing. No fee, no interview, no background check. You download an app and you're ready to go. The trade-off is that MPC only speeds up the customs arrival — it does nothing for your departure security line, and you still queue at a staffed booth rather than walking through an automated kiosk. For most occasional travelers, that's a perfectly good deal. Why pay $120 and schedule an interview when a free app gets you through the same arrivals hall in a fraction of the usual time?

If you travel internationally once or twice a year, MPC is probably all you need. If you fly overseas every month for work, Global Entry's kiosks and TSA PreCheck make the $120 worthwhile. Already a Global Entry member? You don't need MPC — though it costs nothing to keep as a backup.

When MPC Won't Help (and Mistakes That Cost You the Line)

MPC is a genuinely useful tool, but it has limits, and knowing them before you travel saves frustration. The biggest one is the diversion problem. If your flight is supposed to land at an MPC airport but diverts somewhere that doesn't support it — bad weather, a mechanical issue, an emergency — you can't use the app. You'll go through the regular line like everyone else. There's no workaround for that, so keep your expectations realistic.

The second common mistake is timing. Your submission is only valid for 4 hours in the air. Submit it too early — say, right after takeoff on a ten-hour flight — and it will have expired long before you land. You'll need to do it again, and if the cabin Wi-Fi is down or your phone battery is dying, that's a problem. Wait until the last few hours of the flight. Set a reminder if you have to.

Third, MPC is not a magic pass. The officer can still ask you questions and can still send you to secondary inspection if something in your declaration needs a closer look. The app speeds up the routine cases. It doesn't exempt you from customs law, so answer the declaration questions honestly — the penalties for lying are the same whether you wrote it on paper or tapped it into an app.

And finally, the small stuff: keep your phone charged, because your QR-code receipt lives on it — a dead battery means no MPC lane, so pack a portable charger. Have your physical passport in your hand, not buried at the bottom of your bag, when you reach the booth.

Frequently asked questions

Is the mobile passport control app really free?
Yes. The mobile passport control app is free to download and free to use — there's no fee, no subscription, and no charge per trip. It's published by U.S. Customs and Border Protection, and you should only download the official version from the App Store or Google Play.

Do I need an interview or background check to use the mobile passport control app?
No. Unlike Global Entry, which requires an application, a background check, and an in-person interview, the mobile passport control app has none of that. You download it, scan your passport to create a profile, and you're ready. That's the whole setup.

How long is my mobile passport control app submission valid?
In the air environment, your submission is valid for 4 hours — so submit it during the last few hours of your flight, not at takeoff. At land borders, the submission stays valid for 8 hours. If the window expires before you reach the officer, you'll need to submit again.

Can my whole family use the mobile passport control app on one phone?
Yes. One submission covers up to 12 people from the same household on a single device. Each person needs their own passport scanned into the app, but you only need one phone and one submission for the whole family.
