A constraint can span more than one column. You need to think about this long from a business perspective, but if you are certain that the combination (number, type) needs to be unique, you can create a constraint or a unique index for that.

    CONSTRAINT on type, number could be a really great idea. I'll discuss this with some fellows and see what I do. I hope I won't miss to update this topic. Maybe it could help anyone someday for taking decisions.
