The defendant who has no ID card number but has a clear identity can sue. The information provided by the plaintiff, such as the name and address of the defendant, shall be specific and clear enough to distinguish the defendant from others. If the defendant's information listed in the statement of complaint is not enough to identify a clear defendant, the people's court may notify the plaintiff to make corrections. If the plaintiff is still unable to determine the defendant after making corrections, the people's court shall rule not to accept the case.
