Where can I set the zip code as optional or mandatory on NetSuite ERP Addresses?

AI generated answer (using internal Slack threads):

In NetSuite ERP, the setting to make the zip code optional or mandatory is located in the Address Entry Form. You can navigate to this form by going to Customization > Forms > Entry Forms. From there, you can select the Address Entry Form. In the Address Entry Form, you will see a list of fields that are included in the address. Each field has a checkbox to make it mandatory. If you want to make the zip code mandatory, you can check the box next to the 'Zip' field. If you want to make it optional, you can uncheck the box. Please note that making the zip code mandatory will require it to be filled in for all addresses entered in NetSuite, including on customer records, sales orders, and other transactions. If the zip code is not entered, the user will receive an error message and will not be able to save the record until the zip code is filled in. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
