Postcode format regex

[Rhian.Lowe]

Hi.

Could somebody please help me with the expression that needs to go in the Regex match pattern field to check if the incoming postcode is a valid format? It needs to detect whether there are too many spaces in the middle as well as the usual O instead of 0.

Thanks
Rhian

HI Rhian,

If you want to check the spaces two or more you can use this regular expression pattern -  "[ ]{2,}" 

You can use instring  function  to verify this - "the usual O instead of 0."
