So your searching for your venue, and you don't find it. Now what?
Untappd uses Foursquare for all venues. To add a venue, you need to create a foursquare account, and create a venue via their Mobile App or via the web at https://foursquare.com/add-place. Once the venue has been created and you check-in into it - it will show up in your search in the "Add Location" screen.
I repeat, we cannot create venues in Untappd, all venues must be created in Foursquare first.
If you created the venue as "home" category - please make sure you follow these steps to make sure it's searchable:
