Doesn't != imply that it is a text question? Why wouldn't it work as a number question? My solution was just the same, but in number using

AND( NOT(ISBLANK( MailingPostalCode__c )), MailingPostalCode__c != ShippingPostalCode__c )

I got the issue. You are using custom field (__c) but we need to use saleforce standard field only. And According to task we also need to check IsBlank for account level check also. We need to execute below formula only when Acount lookup is not blank on contact object.


AND( NOT(ISBLANK(AccountId)), MailingPostalCode != Account.ShippingPostalCode )
NOTE:- All API name also mention in task. 

Please let us know if this will help you

I know this is an old thread, but can someone please explain to me why the != was needed?  It was my missing link per say in passing this challenge, but cannot figure out why.

Hi

Try using the below code. Also make sure you are putting this validation rule on Contact and not Account.

 

AND( 
NOT(ISBLANK( Account.Id )), 
MailingPostalCode != Account.ShippingPostalCode 
)
