The field settings for Zip Code and Postal Codes have an additional option that will add a leading zero (for 4-number zip codes) or will format the Postal Code to its standard format.


For US Zip codes you can opt to correct US zip codes that are missing a leading zero.   See the checkbox at the very bottom of the screen below.

Please note that this functionality is limited to database registered in the US.


For UK Post codes, you can opt to correct the formatting of a UK Postcode using the field setting at the very bottom of the image field settings page

Please note - this functionality is only available for databases registered in the UK.


For Canadian Postal Codes, much like the UK Postcode setting, you can opt to correct the formatting of a Canadian Postal code using the field setting at the very bottom of the image field settings page 



Please note - this functionality is only available for databases registered in Canada.
