Even if we put some coplicated logic to prevent the input of wrong symbols, check the consistence of the data and do whatever possible to make sure that it is all OK, there is still possibility that the users enter the wrong number. Though all said, we must try to prevent the most of human errors and the best way to do this is by using Regular Expressions.
