If you’re wondering whether someone has added you on Snapchat, there are a few ways to check. One way is to look for their username in your Snapchat friends list. If they’ve added you, their username will appear in the list, and you’ll be able to send them snaps and messages.
Another way to check if someone has added you on Snapchat is to look for their Snapcode. A Snapcode is a unique QR code that you can scan to add someone on Snapchat. If someone has added you, they will have sent you their Snapcode, and you can scan it to add them back.
