Your unban request, matched to the lock on your Snapchat

Your username, your lock type, one request: Snaplocked sends it for your locked Snapchat account, automatically.

The next page asks for your Snapchat username.

The four Snapchat locks, side by side

Pick yours in the row at the top, the request goes out for that one.
Lock	What Snapchat does	Snapchat's own route
Temporary lock	Locks the account for a while after suspicious activity, such as many friend requests in a short time.	Wait 48 hours and log in again, or log in at accounts.snapchat.com and choose Unlock.
Permanent lock	Locks the account for content or behaviour against its Community Guidelines or Terms.	No self unlock. An appeal only when the app shows Appeal Decision.
SS06 device ban	Blocks logins from a device it has banned, whatever the account.	Not covered on its locked account page.
Third-party app lock	Locks accounts accessed via an outside app, tweak or plugin.	Wait out the period shown, remove the app, update Snapchat, log in.

More information
Snapchat lists every lock reason above on its own help page: Snapchat Support, My Snapchat account is locked

Logging in from a banned device locks an account
Snapchat names it as a lock reason, which is why a fresh account on the same phone can end up locked too.
An in-app appeal can take up to 30 days
That is the review time Snapchat gives, and only for accounts that see the Appeal Decision pop-up.
What the SS06 code means, word for word
Snapchat's locked account page never names it. That is why the request asks you to pick the lock you see.
Which of the five reasons affected your account
Snapchat lists five reasons for a lock; only the message in your app or email can say which one applies.

The app states your account is permanently locked
The Unlock button at accounts.snapchat.com will not open it. Look for Appeal Decision in the app; with none, pick Permanent lock above and send the request.
Login fails with SS06
The block sits on the phone, so changing accounts on it changes nothing. Pick SS06 device ban above and send the request for that device.
Still locked after 48 hours
The temporary wait is over and the lock stayed. Remove any outside app or tweak, update Snapchat, then send the request with the lock you see now.

A new account gets around the banFalse
Snapchat locks accounts that log in from a banned device. Submit the request for the device instead of starting over.
Every Snapchat lock is for goodFalse
Snapchat also locks for a while: wait 48 hours, then log in or use Unlock at accounts.snapchat.com.
You can always appealHalf true
Only accounts that see Appeal Decision in the app can. Without it, send the unban request from here.
