Swapping vehicles during a New York car hire can happen for practical reasons, a mechanical issue, an upgrade, or a branch transfer. The problem is that NYC parking enforcement looks at the number plate, not your intentions. If your parking app still shows the old plate, you can pay correctly and still be ticketed.
This guide walks through the safest, step-by-step way to update the registered vehicle in common NYC parking apps after a swap, and exactly what proof to keep. The aim is simple: ensure the plate in the app matches the car at the kerb, and ensure you can prove it later if you need to dispute a PCN.

Before you change anything, do these 3 checks
1) Confirm the plate exactly as printed. NYC apps typically expect the plate without spaces or dashes, but you should enter it exactly as the app formats it. Compare the plate on the car with the rental paperwork, they should match. If they do not, sort that first with the rental provider.
2) Find out what you are parked under. Are you using a city meter, a ParkNYC zone, a garage app, or a municipal lot? The app you need to update is the one connected to the payment method for that location. If you are unsure, check your email receipt or app history for the brand name and zone number.
3) End any live session before swapping cars. If you can, stop the parking session before you hand the old car back. Some apps do not allow editing a plate on an active session, and even when they do, enforcement may have already scanned the old plate.
What to do at the swap counter, the “proof pack” to collect
When your car hire vehicle is swapped, build a quick proof pack before you leave the desk or lot. You want evidence that links old plate, new plate, date and time, and your account.
Keep these items:
Swap receipt or revised rental agreement showing the new vehicle details, especially the number plate and the effective time/date. If it is emailed, screenshot the email header with the timestamp.
A photo of the new number plate on the vehicle, plus a photo of the VIN plate sticker inside the door jamb if visible. This helps if the plate was mistyped.
Counter or agent note if there was a mechanical issue or forced swap. Even a short written note can support a dispute later.
A screenshot of your parking app account page showing your name/email and the time on your phone. This helps tie your payment history to you.
General steps that work for most NYC parking apps
Apps vary, but the sequence below reduces the risk of enforcement mismatch.
Step 1: Stop or let expire the existing session. Open the app you used last, locate “Active session” and end it. Screenshot the ended session confirmation page, including zone, time and the old plate.
Step 2: Add the new vehicle. Go to Vehicles, Cars, or Payment settings. Choose “Add vehicle” and type the new plate. Double-check every character, NYC plates can mix letters and numbers that look similar.
Step 3: Set the new plate as default. Many apps let you store multiple vehicles. Ensure the new plate is selected before starting another session. If there is a star, tick, or “Default” label, confirm it.
Step 4: Start a test session if you are parking again soon. If you will be parking again within a few minutes, start a short session and screenshot the confirmation page showing the new plate. End it if you do not need it, but keep the proof.
Step 5: Save receipts immediately. Turn on email receipts if the app offers it. If not, screenshot the “Receipt”, “History”, or “Parking sessions” screen after each paid session until you are confident everything is tracking under the new plate.
Step-by-step, ParkNYC (common for NYC on-street meters)
ParkNYC is widely used for city parking zones. The wording can change slightly by app version, but the flow is usually consistent.
1) Open ParkNYC and check for an active session. If you see a running timer, end the session. Take a screenshot showing it ended.
2) Go to the menu, then Vehicles. Look for “Vehicles”, “My Vehicles”, or a car icon. Select it.
3) Add the new plate. Tap “Add vehicle” and enter the new plate. Pick the correct state if prompted.
4) Set it as the current vehicle. Return to the main screen and confirm the selected vehicle matches the new plate before choosing a zone.
5) Start parking and capture proof. When you begin a session, screenshot the confirmation that includes zone number, start time, end time, and plate. If enforcement comes by later, that screenshot plus the receipt is often the fastest way to show you paid for the correct vehicle.
Step-by-step, ParkMobile (common across the US, sometimes used in NYC facilities)
ParkMobile is often used for lots, garages, or certain areas, and travellers may already have it set up from elsewhere.
1) Stop any active parking session. If the app shows an active session, end it before you change vehicles. Screenshot the end screen.
2) Open Account, then Vehicles. Depending on the app version, this may be under Profile or Settings.
3) Add vehicle, then select it. Enter the new plate and save. Make sure the new plate is selected for your next session. If the app shows a “Primary” vehicle, set the new plate as primary.
4) Verify with the next purchase screen. Before confirming payment, review the plate field on the checkout screen. Screenshot that screen as well as the final confirmation page.
Step-by-step, Passport Parking (often used by municipalities and some NYC-adjacent areas)
If your trip includes parking outside Manhattan or in nearby areas during a New York car hire, you might encounter Passport Parking.
1) End any running session. Take a screenshot showing the session ended and the plate used.
2) Navigate to Vehicles or Vehicle Manager. Add the new plate and save.
3) Confirm the selected vehicle on the “Start parking” page. The app typically displays the plate near the zone field. Do not proceed until it matches the new car.
4) Keep the receipt and session history. Screenshot the receipt and the session entry in history, especially if you later need to appeal.
If you swapped cars while already parked, what to do immediately
Sometimes the swap happens while you are in a garage, or you park, then later discover the wrong plate is in the app. If you are currently parked:
1) End the session now. Even if you paid, end it, screenshot the end confirmation, and start a new session under the correct plate.
2) If the location requires the original session to remain active, contact support in-app. Some facilities validate a session against the gate system. Use the in-app help chat or email, and attach the swap paperwork and both plates. Keep a screenshot of the message you sent.
3) Put a note in your phone. Write down the exact time you swapped vehicles and the exact time you updated the app. Those timestamps matter if enforcement scanned the old plate in between.
What screenshots and receipts to keep, minimum checklist
Keep these until at least a few weeks after your trip, longer if you receive mailed notices.
Screenshot A: the old session ended screen, showing old plate and timestamp.
Screenshot B: the Vehicles list showing the new plate added.
Screenshot C: the new session confirmation screen showing new plate, zone and time.
Screenshot D: the session history entry and/or receipt page for the new session.
Receipt E: email receipt (if available) for each session after the swap.
Document F: revised rental agreement or swap receipt showing new plate and effective time.
Tip: keep screenshots in a dedicated album labelled “NY parking”. If you are disputing a ticket, being able to share them quickly matters.
How to reduce ticket risk after a New York car hire swap
Double-check the plate every time you start a session. Many people store multiple vehicles, and apps can revert to the previously used plate after an update.
Avoid “favourite” shortcuts until you verify the vehicle. Saved locations can auto-fill an old plate.
Keep the zone number and street details. If your payment is correct but the zone was wrong, your receipt still helps, but it may not fully clear the ticket.
Know that enforcement timing is not in your control. A scanner car can log plates quickly. That is why ending the old session and starting a new one with proof is safer than editing mid-session.
Got a ticket anyway, how to build a strong dispute pack
If you receive a ticket after the swap, do not rely on one piece of evidence. Combine proof that you paid, proof of the vehicle swap, and proof of timing.
Include: the ticket photo (if available), your app receipt showing payment, your session confirmation screenshot showing the correct plate, and the revised rental agreement showing the swap time. Add a short statement explaining that the vehicle was swapped mid-trip and you updated the plate as soon as possible.
Match timestamps clearly. Put the key times in order: swap time, app update time, parking start time, and ticket issuance time. If there is a gap, explain it plainly.
Keep it factual. Disputes tend to go better when your documentation is clear and your timeline is easy to follow.
FAQ
Q: Can I just edit the plate on an active parking session?
A: Sometimes, but it is risky. The safest approach is to end the session, add the new plate, then start a new session and screenshot the confirmation.
Q: What if I swapped cars but the rental paperwork email arrived later?
A: Screenshot any temporary swap note at the counter, plus a photo of the new plate. When the revised agreement arrives, save it and keep both versions together.
Q: Do I need to delete the old vehicle from the app?
A: Not usually. Keeping it is fine, but make sure the new plate is set as default, and always check the plate field before paying.
Q: I paid in the app but received a ticket for “no standing” or a restricted time. Will proof help?
A: Payment proof can confirm you attempted to comply, but it may not cancel a restriction-based ticket. Still keep receipts and screenshots, as they may support your explanation.
Q: What is the minimum proof to keep after a swap?
A: Keep the revised rental agreement showing the new plate, plus the app confirmation screenshot and receipt for the first session you paid after the swap.
