Quick Summary:
- Use the printed temporary tag number, not the VIN, for ANPR entry.
- Check both rear window tag and rental agreement for matching plate details.
- If the camera cannot read, pay by kiosk or app and save receipts.
- Photograph tag, windscreen, and timestamped payment confirmation to dispute overcharges.
Automatic Number Plate Recognition, often called ANPR, is common in Miami parking garages, airport lots, and many private car parks. It works smoothly when a standard metal licence plate is clearly visible. With car hire vehicles, though, you may receive a temporary registration tag printed on paper and displayed behind tinted glass, usually in the rear window. That combination can confuse camera systems, and it can confuse drivers too, because you are often asked to enter a “plate number” when paying.
This guide explains how to identify the correct plate number to type in, what to do when scans fail, and what proof to keep so you can avoid overcharges or admin fees later.
Why temporary tags and tinted glass cause ANPR problems
Temporary tags in Florida are typically paper, with smaller characters and more visual clutter than a permanent plate. When they sit behind a dark tint, reflections and low light can make them hard for cameras to read at entry or exit. Some systems then guess a partial plate, log “unknown”, or attach your entry to the wrong vehicle.
In Miami, you will encounter several variations of camera parking: barrier-controlled garages that open automatically, ticketless systems that ask for your plate at a pay station, and app-based payments where you must enter the plate manually. Each relies on an accurate plate string. If you enter the wrong characters, you can get charged twice, or receive a later “non-payment” notice even though you paid.
Step one: find the correct number to enter
When a parking machine or app asks for your plate, you almost always need the registration number displayed on the temporary tag itself, not the Vehicle Identification Number (VIN), not the fleet number, and not a contract reference. Here is how to locate and confirm the correct string.
1) Check the rear window temporary tag. Stand behind the vehicle and read the tag carefully. Look for a labelled field such as “TAG”, “PLATE”, “LIC#”, “LICENSE”, or “REG”. The plate number is usually a short combination of letters and digits. Ignore other fields like issue date, expiration date, county, dealer number, barcode strings, and any large red “TEMP” wording.
2) Compare it with the rental agreement. Your agreement often lists “Licence plate”, “Plate”, or “Tag”. If the agreement shows a plate number, it should match the visible temporary tag. If it does not match, treat that as a warning sign and clarify before you rack up multiple parking sessions.
3) Look for a second display location. Some vehicles may also have a temporary tag displayed in the windscreen, or a small sticker with the same number. Do not assume the number on a windscreen sticker is the plate unless it explicitly says so.
4) Distinguish common lookalikes. ANPR systems and humans mix up 0 and O, 1 and I, 5 and S, 2 and Z, 8 and B. If the font is hard to read through tint, use your phone camera to zoom in and sharpen the image, then compare with the contract plate field.
If you are collecting a vehicle around Downtown or Brickell, you may see more garages that require manual plate entry at payment. It helps to confirm the temporary tag number before you drive away, especially if you picked up via a central location such as car hire in Brickell.
What to enter in apps, kiosks, and pay-by-plate machines
Pay-by-plate kiosk: Enter exactly the plate string shown on the temporary tag, with no spaces unless the screen formats it. If the keypad offers a choice of “state”, select Florida if available. If it asks for “plate type”, choose temporary if listed. If temporary is not listed, proceed as standard, but keep proof of payment (more on that below).
Parking apps: Many Miami facilities use app payments where you provide the plate and a zone code. Enter the temporary tag plate exactly, then take a screenshot of the confirmation page that shows the plate, the zone, and the time range.
Pay on exit: If the barrier does not lift because the camera cannot match your exit to a paid session, do not reverse into traffic. Use the intercom or “help” button and tell the operator you have a temporary tag behind tinted glass. Offer the plate number you paid for and the payment time. If you paid at a kiosk, have the receipt ready.
If ANPR cannot read your temporary tag, do this immediately
Problems are easiest to fix while you are still at the car park. Your aim is to create a clear trail that links your vehicle, the temporary tag number, and your payment.
1) Pay using an alternative method. If the system fails to recognise you, look for a staffed booth, a pay station that accepts manual entry, or an app option. In many garages you can still pay by entering the plate manually even if the camera entry did not log correctly.
2) Use the help button and ask for a manual override. Operators can often open the barrier and log a note against the session. Be ready to provide: plate number, entry time, location name, and payment reference.
3) Keep the machine receipt, even for zero balances. Some systems print a receipt showing “Paid” or “$0.00 due” with timestamps. That can be valuable if a later charge appears.
4) Avoid creating two live sessions. If you start payment in an app and then pay again at a kiosk because you are worried, you may end up with two valid charges. If you must switch methods, cancel the first attempt if possible, or keep evidence showing it failed.
These steps are especially relevant if you are driving between Miami and Fort Lauderdale and using airport parking or hotel garages. Facilities around FLL can be heavily automated, so it is helpful to know your tag details if you arranged a pickup such as car hire at Fort Lauderdale Airport.
What proof to keep to avoid overcharges and admin fees
If a parking operator later claims you did not pay, or if the ANPR system matched the wrong plate, your evidence should be simple and time-stamped. Create a mini “packet” on your phone as soon as you park.
Photo 1: the temporary tag close-up. Stand outside the vehicle and photograph the tag so the plate number is readable. Take a second photo from farther back showing it is on your vehicle. If the tint makes it unreadable, open the boot or adjust your angle to reduce glare, without removing the tag.
Photo 2: the whole rear of the car. Include the make, model, and location context if possible, such as a sign or bay number.
Photo 3: payment proof. Photograph the printed receipt, or take a screenshot of the app confirmation page. Ensure it shows the plate, time, date, amount, and location or zone. If the app only shows a transaction ID, capture that too.
Note: entry and exit times. If you can, note the time you entered and left. A quick note in your phone can support a dispute if the operator claims you stayed longer.
Keep your car hire agreement page. Save a photo or PDF page that displays the plate or tag number allocated to you. If the agreement does not show a plate, photograph the vehicle information section and the tag on the car.
This documentation is also helpful if any tolling or vehicle identification questions arise during your trip. If you are collecting near Miami International Airport, it can be useful to know the operator details for your vehicle type, for example National Car Rental in Florida (MIA) or Alamo car hire in Florida (MIA), because different fleets format paperwork differently.
Common Miami scenarios and how to handle them
Scenario: the pay machine rejects your plate format. Some systems expect a fixed number of characters and may not accept shorter temporary tags. Try entering without spaces or hyphens. If there is a “state” dropdown, selecting Florida can change validation rules. If it still fails, switch to pay-by-ticket or pay-by-time if available, then save proof and contact the operator via the help button.
Scenario: the garage opens on entry but not on exit. This can happen when entry is logged as “unknown” and your later payment cannot attach to it. Use the intercom, provide your plate and payment proof, and request a manual exit. Then keep a photo of the barrier area and the time, in case a post-trip charge appears.
Scenario: you received a parking notice after you paid. Do not ignore it. Compare the plate on the notice with your temporary tag. If one character is wrong, that points to a misread. Send your photo evidence, receipt, and agreement plate field to the operator’s dispute channel. Keeping everything time-stamped makes this a straightforward correction.
Scenario: valet parking asks for your plate. Give them the temporary tag plate number and mention it is behind tinted glass. Ask for an itemised receipt that includes the date and location. If your vehicle is a larger model, valets may park it in separate areas, so clarity matters. This is common when using people carriers around the beach areas, including options like van rental in Miami Beach.
Prevent problems before they happen
Do a two-minute check at pickup. Before you drive off, confirm the tag is present and readable, and that your agreement matches the displayed plate. If the tint is extremely dark and you cannot read the tag from outside, take a clear photo while you are still at the location, using angles that minimise reflections.
Ask about toll and parking processing. Some car hire providers pass through tolls and certain parking charges with admin fees. Knowing how your rental company handles third-party charges helps you spot genuine items versus errors.
Keep everything in one folder. A single album with tag photos, receipts, and screenshots speeds up disputes if you need them after returning the vehicle.
Be consistent. If you pay for multiple sessions in the same trip, always use the exact same plate string. Switching between a guessed plate and the correct one is a common reason drivers get double charged.
FAQ
Which number do I enter for ANPR parking on a Miami hire car with temporary tags? Enter the registration or tag number printed on the temporary paper plate. Do not enter the VIN, stock number, or your rental agreement reference.
What if the temporary plate is hard to read behind tinted glass? Use your phone camera to zoom and reduce glare, then match the characters against the plate field on your rental agreement. Take a clear photo for your records.
What should I do if the barrier will not open because the camera cannot scan my plate? Use the help button or intercom, explain you have a temporary tag, and provide the plate number and payment proof. Request a manual override and keep your receipt.
How can I avoid being overcharged after I have already paid? Keep photos of the temporary tag, the rear of the vehicle, and a timestamped receipt or app confirmation showing the plate, location, and time range.
Can I dispute a parking notice if the ANPR system misread my temporary tag? Yes. Send the operator your paid receipt, screenshots, and a photo of the temporary tag showing the correct plate, plus your rental agreement page if it lists the plate.
