Why Is My Steam Account Restricted From Trading?

Your Steam account may be restricted from trading for the following reasons: 1. Steam Guard Mobile Authenticator has not been enabled for at least 15 days. 2. Your account has been flagged for suspicious activity or fraudulent behavior by Steam. 3. You have recently changed your Steam account password or email address, which may trigger a temporary trade restriction. 4. Your account has been banned or restricted by Steam for violating their terms of service. 5. You have not made any purchases on Steam in the last year, which may result in a trade restriction. If your account is restricted from trading, you will not be able to sell items on our platform until the restriction is lifted.
