Hi all,
Has anyone found a good solution or workaround for handling the 4-digit ZIP code extension (ZIP+4) in addition to the standard 5-digit US ZIP code in Salesforce? Unfortunately, it seems Salesforce doesn't support this out of the box, especially for address fields on standard objects like Accounts. I'd be really interested in hearing how others have approached this – whether with custom fields, validation, integrations, or third-party tools, advantages, disadvantages.
