If you're seeing an SS18 or SS06 error code when trying to log in or create a new account, this means Snapchat has banned the device you're using due to abuse or repeated violations of our Community Guidelines. This is a safety measure we take to protect the Snapchat community when we identify suspicious activity.
If you're seeing an SS07 error code when trying to log in, this means your device has been banned from logging into Snapchat because too many accounts have been associated with the device.
If your device has been banned, you will not be able to create new accounts on a banned device. Please note that the appeals process in the Snapchat app is the only legitimate way to appeal an account lock decision, including if your device has been banned.
