You can search in the HONK app by ZONE ID by choosing the 'By Zone ID' option and then entering the exact zone ID you are looking for, and taping on 'Search'. You will then land on the purchase page for this zone.
You can also search by address, by choosing the 'By Address' option and typing in an address or common landmark to view locations in the area. You can then click on the little flags that pop up to view the locations details and rates.
Lastly you can search around you using a map.
With the web app, it's interactive. You can click and scroll to view an area on the map and any HONK locations will populate as you scroll.
If the app gives you a message that a location you are trying to view is further than 15 kms / 9 miles away and you know that you are not, it means you need to turn on locations services for the app.
