Parking purchased on a partner website or as part of a parking package are non-refundable.

If you received a promotional discount code from ParkWhiz, you'll want to be logged into your ParkWhiz account before applying the code on the checkout page. Make sure you’re using the same email address to log in as the one where you received that coupon!

Note that all discount codes will come from ParkWhiz directly. If you received your code from a third-party website, there's a significant chance it will not work. Unless specifically noted, discount codes cannot be used for monthly parking.

If you were issued ParkWhiz credit, the credit will automatically deduct from your total on the checkout page before your next purchase. Be sure you're logged in under the account to which the credit was issued before confirming that purchase, to see the credit applied.

Easy peasy! As the vast majority of locations in our network accept a mobile pass, this means you can use your phone or other smart device to show proof of your prepaid purchase once you arrive at the parking facility. To be sure, verify the instructions on your pass to confirm the validation method. That section is titled "When You Arrive" in-app or "How To Park" if viewing on a desktop or mobile web.

For a seamless, no-printer-required experience, check out the ParkWhiz app! Thousands of space at your fingertips. Rest assured that if searching and booking on a mobile device, we won't show you any locations that require a printed pass! At least not until cars come equipped with printers!

If your location does not accept mobile passes, you'll need to print the pass before leaving the house.

In most instances, no. The majority of locations on ParkWhiz, including all those in New York City, do not allow re-entry.

If any specific parking facility does allow for you to come & go during the reserved timeframe, you'll see a "Reentry Allowed" amenity icon listed; this is shown in the details section both pre-purchase and post-purchase.

If you don't see anything on the listing page pertaining to specifically to reentry privileges, it's best to assume that you will not be allowed to come and go throughout the duration of your parking pass.

Generally, no. What you see online is what you pay as long as you park within the timeframe on your parking pass. Any time parked outside the arrival or departure listed on your pass will likely incur an additional onsite fee, as determined by the parking provider. ParkWhiz purchases include tax.

The only exception to the above pertains to oversize vehicle fees, which may apply to any vehicle larger than a sedan. Fee amounts vary between individual Parking Operators, and will be assessed on-site if you do not prepay for an oversize vehicle through our platform.

Although pricing structures are determined individually by the facility owner/operator, ParkWhiz prices tend to be cheaper than drive-up in most cases! If you ever feel the rate on ParkWhiz was more expensive than drive-up, take a photo of the price on-site and send us an email! We love deals as much as you do and are eager to ensure you're getting a fair rate.
