Postal code anomize

Hello,
I would like to anonymize the field cb_zipcode in the output.
This means when registering, the postal code must be completely entered (12345), but in the profile view I want an anonymized issue (12 ...). Output without brackets.
How can I implement that?

Many Thanks

We've no way of doing that without some form of coding to cut the field value short. So you'd need CB Code Field for that then write the necessary PHP to output it cut short. It's likely better to just not output zip code on profile as a partial zip code isn't really useful information for anyone.
