How to Find Friends on Snapchat
To find friends on Snapchat:
Snapchat pulls your contacts from your mobile device. All your potential friends are sorted alphabetically. To add a friend to your snapchat list, click on the circle that appears next to their name, which will result in a check mark by their name.
If you know someone’s Snapchat username, but they are not in your Contacts, you can search for them within “My Friends.” This method is not foolproof so exercise care.
If you do not change a feature in “Settings,” that allow you to only receive snaps from your friends, you will be able to receive snaps from strangers.
