Yes, you can. The location tag you create could be for anywhere, such as your business address. Or you could create a fictional place and create a tag for there too, for example, "My House." To do this, you will need to use both Facebook and Instagram, as they are interlinked and owned by the same company. Creating a custom location on Instagram is simple and requires only a few steps: 1. Launch your Facebook app and sign in. 2. Create a post by tapping on "What's on your mind." 3. Select "Check In." 4. In the search bar, type the name of the location you want to create. If a location with the same name already exists, you will need to change yours slightly to make yours unique. 5. Press "Search" or "Done." 6. Scroll to the bottom of the screen and tap "Add [Name of your location]." 7. Fill in the "Place name," "Address," and "City," and then tap "Save Custom Place." 8. You can now navigate out of Facebook. The next step is to use this location in Instagram: 1. Open your Instagram app. 2. Navigate to the post you want to change the location on and tap on it to open it. 3. Click the three-dot icon at the top right of the screen and choose "Edit." 4. Select the existing location under your username. 5. In the search bar, type in the name of the new location you have just created on Facebook. 6. When it comes up, tap it to select it. 7. Tap "Done." You have now added your custom location to your Instagram post.
