The Global Entry Mobile App turns a five-minute kiosk wait into a 30-second walk past customs — at the airports where it works.
If you are already an active Global Entry member, this app is the biggest upgrade to the Trusted Traveler Program in a decade. Instead of queuing up at a physical kiosk to take your photo and declare items, the app lets you run the facial recognition match on your own phone while you are still taxiing to the gate.
However, there is a catch. As of right now, it is not supported everywhere. You can check our complete list of supported airports to see if your next arrival gateway is on the roster.
If it is, you are in luck. By the end of this walkthrough, you'll know exactly what to do from "phone in your pocket on the plane" to "walking past the inspection desk."
What you'll need before you fly
Before you try to use the mobile lane, make sure you have everything ready. Doing this while standing in the customs hall defeats the entire purpose of the app.
- An active Global Entry membership. You must be a fully enrolled member with a Known Traveler Number (KTN). "Conditionally Approved" status does not work.
- The official CBP Mobile App. Download it on iOS or Android.
- Your profile already set up. You need your physical passport for this one-time setup step, so do it at home before your trip.
- Cellular or in-flight wifi. The app needs an active internet connection to communicate with CBP servers when you land.
- A charged phone. The app performs a live biometric face match and requires your screen to be on.
Setting up your profile (one-time, do this at home)
Do not wait until you are on the plane to set up your profile. It takes about 10 minutes and requires good lighting and your passport. You only have to do this once.
- Download the app: Search for "CBP Mobile App" in your app store. Ensure the publisher is "U.S. Customs and Border Protection." Ignore third-party apps that charge money.
- Select the program: Open the app and tap the "Global Entry" tile on the home screen.
- Scan your passport: You will be prompted to take a photo of the inside data page of your passport. Good lighting matters heavily here; if there is glare on the MRZ (Machine Readable Zone) at the bottom, the app will reject it.
- Enter your KTN: Input your 9-digit Known Traveler Number. You can find this on the back of your physical Global Entry card (labeled PASSID) or by signing in to the CBP TTP portal.
- Take a profile selfie: Find a plain background, keep your eyes open, and remove your sunglasses. The app validates this selfie against the photo CBP took of you during your initial Global Entry interview.
- Wait for validation: It usually takes a few seconds. If it fails, retry in better lighting. If it repeatedly fails, your CBP profile photo might be too old, which is a known issue we cover in our troubleshooting guide.
Right before landing — the actual workflow
Once your profile is set up, the app is ready for travel. Here is exactly what you should do as your international flight begins its descent into the United States.
- Get connected: As the plane descends, connect to the in-flight wifi if available. If not, wait until the plane touches down and your cellular data kicks in. Do not attempt this on airplane mode.
- Start the process: Open the CBP Mobile App and tap "Start" on the Global Entry tile.
- Select your arrival airport: The app will sometimes auto-detect your location using GPS. If it doesn't, manually select your arrival airport from the dropdown list.
- Take the "this trip" selfie: The app will prompt you for a live selfie. It re-runs the facial recognition algorithm, matching your current face against the profile you set up previously.
- Confirm flight details: You will be asked to confirm your country of origin and answer an abbreviated version of the standard customs declaration questions (e.g., are you carrying over $10,000, are you bringing in agricultural items).
- Get the green check: The app will process your submission and return a bright green checkmark alongside a digital receipt. Screenshot it immediately. Cellular connectivity deep inside terminal buildings can be spotty, and you don't want the app to refresh and lose the screen just as you walk up to the officer.
- Walk to customs: The digital receipt is valid for approximately 4 hours. You have plenty of time to deplane, use the restroom, and take the tram to the customs hall.
At the airport — using the mobile lane
When you finally reach the passport control area, look for the signage. At major gateways like IAD (Dulles) or JFK Terminal 4, the mobile lane is clearly labeled "Global Entry Mobile" or "Trusted Traveler Mobile." It is usually located adjacent to the standard kiosk bank, sometimes separated by a belt stanchion or a glass partition.
The interaction is incredibly brief. Some airports have installed a camera at the very entrance of the mobile lane. It auto-recognizes your face as you walk toward it and signals the officer. At other airports, you simply walk up to the podium and show the officer the green-check screenshot on your phone.
A common point of confusion for first-time users: at some airports, the "mobile lane" is literally just a podium with a CBP officer holding a tablet, with no kiosks behind them. That is completely normal. The officer pulls up your face match record on their tablet, looks at you to verify your identity, and waves you through. The entire exchange takes about 10 seconds.
Tired of checking for Global Entry slots?
Stop refreshing the government portal. We watch your chosen enrollment centers 24/7 and send instant SMS alerts directly to your phone when a slot opens.
If you arrive during off-peak hours or the airport is short-staffed, the dedicated mobile lane might be closed. If that happens, don't panic. Your regular Global Entry membership still works perfectly fine. Just walk up to the standard kiosks, look into the camera, and proceed normally. The app's receipt is a shortcut, not a strict requirement for entry.
When the app is faster — and when it isn't
The Global Entry Mobile App is a massive time-saver, but it isn't a silver bullet for every situation.
Where the app wins: The app is undefeated during peak arrival hours at busy international gateways (like MIA, EWR, LAX, and JFK). When four wide-body jets land at the same time, the line just to use the Global Entry kiosks can back up. Bypassing that physical line with your phone saves you 15 to 20 minutes.
Where the kiosk wins (or ties): If you are flying into a small regional airport at 11:00 AM, there is likely no line at the kiosk anyway. Additionally, if you are traveling with a group of 4 or more family members, the kiosk is often faster. The mobile lane is usually single-file and requires every member to show their phone individually, whereas the kiosk can process families together.
Finally, if you have agricultural items to declare, the app will usually flag you and send you to secondary inspection anyway. The physical kiosk handles declarations much more elegantly in a single workflow.
What to do if it doesn't work
Technology fails. If you find yourself staring at an error screen on the jetbridge, here are the quickest fixes for the most common issues (you can read our deep dive on Global Entry app errors for more detailed solutions):
- Face match failed: Improve your lighting. Step out of the dark jetbridge and into the terminal. If it still fails, use the physical kiosk.
- "Connection error": You likely lost your terminal wifi connection. Disable wifi and switch entirely to cellular data.
- App can't detect your flight: This happens frequently with complex layovers. Manually select your arrival airport from the list instead of relying on auto-detect.
- App crashes on launch: Delete the app completely and reinstall it from the App Store. This is a known issue on specific iOS 17 updates.
The Mobile App makes Global Entry faster for members who already have it. But getting the membership in the first place is the bottleneck — interview slot wait times at most enrollment centers run 4 to 9 months, with some over a year.
Once CBP has conditionally approved you, Appt Helper monitors every U.S. enrollment center 24/7 and texts you the moment an interview slot opens. The kind of slots that disappear in under three minutes if you're refreshing the CBP site manually.
