To claim a business location on Foursquare, users must first create an account or login. They then search for and select their business from the search results. If the listing is not there, they can create a new one by using the app while physically at the location. For the claim, users continue through the prompts, and may need to request verification if claiming multiple locations. Once verified, users can access and manage their listing profiles through Foursquare's Manager Tools.
