License Plate Recognition

What is License Plate Recognition (LPR)?

Your license plate will be your parking permit.

Parking enforcement vehicles now have readers installed on the front corners of the roof that scan the license plates of parked vehicles. Once a plate is scanned and read by the software the information is sent to the secured Parking database for validation. This happens instantaneously, allowing the enforcement officers to cover the entire campus multiple times per day. An officer on foot can only enforce a small section of campus per day.

Not only will enforcement be more efficient, this will also greatly reduce or eliminate counterfeit and stolen permits.  

Multiple Vehicles

University faculty and staff will be able to register up to three vehicles per permit, though additional vehicles may be listed in your profile — only three out of that list will be allowed with one permit at a time. Motorcycles are considered one of your vehicles if you chose to select it as one of the three vehicles allowed. You are be able to access the online Parking Portal anytime to add or remove vehicles (including rentals) from your account and/or permit using directions provided below.

Students will be able to register one vehicle per permit. You will be able to add the vehicle by accessing the online Parking Portal. Any change in vehicle on permit request will be submitted online and approved by Parking. Until approved, please continue to use your vehicle that is currently attached. In emergencies, please contact Parking for assistance. 

Vehicle Registration

Students, faculty and staff can access the online Parking Portal to add, edit or delete vehicles from their account by following the steps listed below.

  • Visit the online Parking Portal at

  • Select "Vehicles" from the top navigation section of the webpage.

  • Login with Purdue career account credentials.

  • Click "Add Vehicle" to add a vehicle to the account, or click the underlined license plate number of an existing vehicle to edit the information.

  • Click "Permits" in the top navigation bar, followed by "View Your Permits."

  • Select a permit number listed.

  • Click "Add Vehicles to Permit" at the bottom of the page.

  • Check the box next to the vehicle(s) to be associated with the permit and select "Add the selected vehicle."

Parking in Gated Garages

For the time being garage parking will not change. Phase II of the project will be to put LPR readers in the gated garages which will eliminate the need to swipe a physical permit. Phase II is still in the early stages, so we don’t yet have a time frame for when it will be completed. Visitors will continue to use the ticket system; that will not be changing.

Department Shared A permit

Details regarding shared permits are still being worked out, but in general terms there will be a new type of permit: the Organizational A (OA). This permit will be a hangtag to be checked out much like the current shared A permit. However, the OA will be able to be associated with many vehicles rather than three as an individual A permit is allowed. The department will assign an agent(s) to manage the permits and plates through the online Parking Portal. More information about this will be coming.

Two Family Members — Both Employees of Purdue

If two family members share vehicles and each has a permit, both vehicles can be registered to both accounts and both may park on campus at the same time. However, if one person has an "A" permit and the other has a "B" permit, only one vehicle may park in the "A" parking lot at a time. Both cars may be parked on campus at the same time if one is in an "A" lot and the other is in a "B" lot, or if either one or both are in a "B" lot since people with an "A" Permit are allowed to park in an "A, B, or C" lots.

Personal Data Retention

Vehicle information is routed to secure servers and is not shared with other departments or outside agencies. 

Vehicle information is stored as long as the permit is valid. For imaged reads that are in compliance, a weekly purge will take place. For imaged reads that are directly connected to a citation, the server will purge the image data associated with that citation within 60 days of ticket payment or final resolution.   

Enforcement and Parking

The license plate is the permit and anyone who parks on campus must have a valid permit. 

The purchaser is responsible for the accuracy of the license plate (and vehicle information in the Parking Portal) at the time a permit is issued. Citations issued due to inaccurate plate information or the inability to scan a plate are the responsibility of the vehicle owner. Refunds are not issued if license plates are entered inaccurately. 

License plates must face the drive lane to be scanned for compliance. A vehicle may be cited if its plate cannot be scanned. 

Physical Permits

Since we are still in the initial stages of implementation, the physical permit still needs to be in the window of the vehicle that is being driven and parked in a university parking space. Parking will send out a communication when physical permits will no longer be needed. This is why it is very beneficial to go ahead and attach the vehicle(s) to that specific permit so that Parking can continue to live test with the equipment and software.   

Motorcycles and Convertibles

Vehicles that currently get an adhesive, unsecured permit will no longer need to do so. Just add the license plate information of those motorcycles to your main permit. Our vehicle database doesn’t currently have much in the way of makes and models for motorcycles, however we are working on getting that information added in the near future.
