ANPR car parks use cameras to read number plates and match them to payments. In Las Vegas, that works smoothly for most rental vehicles with standard Nevada or out-of-state plates. The confusion starts when your car hire arrives with temporary plates, often a paper tag in the rear window or a temporary registration displayed where a plate would normally sit.
The good news is that most ANPR systems can still work with temporary plates, but you may need to enter details carefully at a pay station or in an app. The key is to treat the “plate” as whatever the car park’s system is expecting to match, and to keep evidence so you can prove you paid if the camera could not read the tag.
If you arranged your car hire collection near the airport, the first time you meet ANPR may be at a hotel or shopping garage shortly after pickup. It helps to know what you are looking at on the vehicle and on your rental paperwork.

What ANPR car parks look for in Las Vegas
ANPR cameras typically capture a front or rear view at entry and exit. Software then tries to read a plate string, for example “ABC1234”, and logs a timestamp. When you pay, you either pay by plate, by stall, or by ticket. In pay-by-plate locations, the system checks whether a payment exists for the plate string recorded by the camera.
Temporary plates create two common problems. First, the “plate” may be behind glass, at an angle, or printed in low-contrast text, so the camera does not capture it reliably. Second, the car park may expect a standard plate format, but your temp tag may show extra characters, a different sequence, or multiple identifiers such as a stock number, VIN fragment, and an expiry date.
Because these systems are designed to prevent “lost ticket” leakage, they often assume the camera reading is correct even when it is not. That is why your evidence and correct data entry matter.
Step one, identify what counts as the plate on your hire car
Before you enter an ANPR-controlled car park, take a minute to confirm what identifier is displayed on the vehicle. In Las Vegas you may see one of these setups:
Standard metal plates front and rear. In this case, enter the plate exactly as shown, including letters and numbers only. Ignore state slogans or small registration stickers.
Metal plate on one end, temporary paper tag on the other. Some vehicles might have a single plate and a temporary on the other end, particularly when newly registered or transferred. ANPR may read either end depending on camera placement. If the entry camera reads the rear, use the rear identifier. If signage says “front plate only” or shows a camera facing the front, use the front identifier.
Temporary paper tag inside the rear window. This is common for new vehicles. The readable string might be labelled “Plate”, “Tag”, “Registration”, or “Temp Tag”. If the tag shows both a large bold code and smaller reference numbers, the large bold code is usually the one intended to function like a plate.
Dealer-style temporary plate in the plate holder. Sometimes a temp plate is mounted where a metal plate would sit. Enter the exact text on that temporary plate, not the VIN.
If you are unsure, check your rental agreement for “Plate”, “Tag”, or “License”. Many rental firms list the plate number that the tolling and parking systems should use, even if the physical display is temporary.
How to enter temporary plate details at pay stations and parking apps
Pay stations and apps vary, but the safest approach is consistent. Type what the car park will attempt to match, using the same characters the camera would see.
1) Enter letters and numbers exactly, in order. Do not add spaces unless the on-screen form requires them. If the tag includes a hyphen, most systems want you to omit punctuation. If the tag includes leading zeros, include them.
2) Avoid mixing similar characters. Temporary tags can make “O” look like “0”, “I” look like “1”, and “B” look like “8”. Compare against your paperwork. If the rental agreement lists the plate, trust that over your quick glance.
3) Use the same format for extensions. If an app asks for state, select Nevada only if the temporary tag is a Nevada temp registration. Some rentals in Las Vegas have California, Arizona, or other plates. Choosing the wrong state can stop a match.
4) If asked for “license plate number” but you only have a temp tag, enter the temp tag code. In most pay-by-plate systems, the “plate” is simply the identifier the system records. The camera may read the temp tag code, so that is what should match your payment.
5) If the app allows a plate photo upload, take it. Some parking platforms let you attach a picture or save a vehicle profile. A clear image of the temp tag can support disputes later.
Different suppliers have different fleet practices. If you want to compare companies, Hola Car Rentals provides information on local partners such as Enterprise car rental in Las Vegas and Alamo car hire in Las Vegas. Regardless of provider, your goal is the same, make the identifier you pay against match what the camera is likely to capture.
What to do if the ANPR camera cannot read your temporary plate
Sometimes you will notice a problem immediately, for example the barrier does not open, the screen says “plate not found”, or the pay station will not accept your entry. Other times you only find out later, via a charge, a “lost ticket” fee, or a parking notice posted to the rental company.
If the barrier will not open on entry or exit
Use the help button or intercom. Explain that the vehicle has a temporary tag and the camera may not have read it. Ask staff to confirm what identifier they see in their system, and whether they can manually open the barrier after verifying payment. If you have already paid, quote the time, location, and payment reference.
If the pay station says your plate is invalid
Try these steps in order:
First, re-enter the code carefully, checking O/0 and I/1. Second, if there is an option to select another state or “Other”, try it. Third, if the location offers “pay on exit” by ticket as an alternative, take a ticket if available, but be aware this can conflict with pay-by-plate rules. If you switch method, keep proof of whichever method you ultimately used.
If the app cannot find your vehicle
Some apps try to pull up your entry event before allowing payment. If it cannot find it, it may mean the camera did not read the temp tag at entry. In that case, look for signage with a location code, zone number, or a different payment method such as “pay by space” or “scan QR at meter”. Pay using the method shown on-site, then keep screenshots.
If you are worried about a later ‘lost ticket’ fee
Many garages apply a maximum daily rate if they cannot match an entry to an exit. With temporary tags, that mismatch is more likely. Your protection is documentation, and reporting issues while you are still on-site. If you suspect a read failure, contact staff before leaving and ask them to note the problem against your vehicle identifier and the time.
Evidence to keep so you can challenge fees later
With car hire, parking charges can reach you indirectly, because the operator may contact the rental company using the plate or temporary tag details. The rental company may then pass through the charge and add an admin fee. Keeping clear evidence helps you dispute incorrect charges promptly.
Photograph the identifier on the vehicle. Take a clear photo of the rear temp tag and, if present, the front plate. Include a wider shot showing where it is positioned, especially if it is behind tinted glass.
Photograph the entry signage. Capture signs that mention ANPR, pay-by-plate, payment deadlines, and any instructions for temporary tags. Include the car park name and address if shown.
Keep payment confirmations. Save receipts from pay stations and take screenshots of app payments showing date, time, location, and the plate or tag number you entered.
Record entry and exit times. A quick note in your phone is enough. If there is a dispute about overstay or “no record of exit”, your timeline helps.
Keep the rental agreement page showing plate or tag. Many agreements show the vehicle’s plate number and VIN. If the temporary tag changes during the rental, ask the rental desk to provide updated documentation and photograph the new tag.
Keep any intercom reference. If staff help you at the barrier, ask for a reference number or the attendant’s name and the time. Even a note of “spoke to attendant at 19:10” can help later.
Common temporary plate scenarios in Las Vegas car parks
Hotel self-parking with pay-by-plate kiosks. These often require you to enter the plate at a kiosk, sometimes inside the lobby. If your car has a rear-window temp tag, the entry camera may struggle. Enter the temp tag code exactly, and keep the receipt. If the kiosk asks for “last four digits” or a shorter code, follow on-screen instructions rather than inventing a number.
Shopping centres and garages with validation. Validation systems may require you to type your plate into a shop tablet. Use the same identifier each time, and take a photo of the validation screen if it displays a confirmation number. If staff cannot find your plate in their system, it may indicate the camera did not capture it.
Airport-area lots. These can be strict on matching entry and exit reads. If you are returning a vehicle and using short-term parking, ensure the identifier you pay against matches what is displayed at that moment, not what you remember from earlier in the trip.
Practical tips to reduce ANPR errors with temporary tags
Clean the rear window. Dust, glare, and tinting can reduce readability. A quick wipe can help a camera capture the tag.
Do not cover the tag. Avoid placing luggage, sunshades, or stickers where they block any part of the temporary plate.
Park to make the tag readable at pay-by-plate enforcement drives. Some locations use roving enforcement vehicles rather than fixed cameras. If your temp tag is in a dark rear window, choosing a brighter bay can reduce misreads.
Prefer staffed garages when you know you have a hard-to-read tag. If you notice the temp tag is curled, faded, or behind heavy tint, a staffed exit can resolve issues faster than a fully automated barrier.
Check your charges early. With car hire, it is easier to correct a parking issue while you still have the receipts and the vehicle photos. If you receive a post-trip charge, respond with your evidence promptly and clearly.
FAQ
Do ANPR car parks in Las Vegas accept temporary plates on a hire car? Yes, many do, but success depends on readability and you entering the same identifier the camera records, often the temp tag code.
What number should I type if my temporary tag shows several codes? Use the code labelled as the plate or tag number, typically the largest bold alphanumeric string, and cross-check with your rental agreement.
What if I paid but later get a ‘lost ticket’ fee? Gather your receipt, screenshots, and photos of the temp tag and signage, then dispute the charge with the operator and your rental provider using timestamps.
Should I tell the rental desk my car has temporary plates? It can help. Ask them to confirm the plate or tag number on the agreement, and keep a photo of the display on the vehicle in case it changes.
Can I switch to taking a ticket instead of pay-by-plate? Only if the car park offers it and signage allows it. If you switch methods, keep proof of the method you actually used to avoid duplicate charging.
