If you want to share your Snapchat username with someone, there are a few different ways you can do it. One way is to simply tell them your username. Another way is to add them as a friend on Snapchat by entering their username into the search bar and tapping on their name when it appears. Once they appear in your list of friends, you can tap on their name and select the option to share your username. You can also share your Snapchat username via other social media platforms such as Facebook, Twitter, or Instagram by posting it on your profile or in a status update.
