Hi,
Use this Regex to allow only certain digit.
^(\d{9}|\d{11})$

Regular expression is probably the best way to implement this, however, it is slightly complicated to learn and design the expression.
Reference is found here and all over the Internet.

You will need to decide what acceptable pattern is. It might be lot more complicated than you have stated in the question.
