Validation of postcodes


Is there an easy way for FileMaker 10 to deal with the validation of postcodes or ZIP codes if in the US?


I want to be able to validate the following types of postcodes.  Here are three examples. 



  • HT14 6GH - This one is acceptable
  • 3RT B14     - This one is unacceptable because the first part starts with the number 3 and the second part starts with the letter B.
  • S2 4PQ - This one is acceptable.



 Not sure how to tackle this one in FileMaker. I believe in Access you would use input masks.


Any help appreciated
