You would need to connect to a datasource which contains Address, ZipCode and PhoneNumber. Tableau cannot do this lookup automatically, no such source exists within the tool.
In terms of building the source above, perhaps there are API's available which would allow you to build such a source but it seems like a big ask to me as that datasource would be massive.
I think your best option would be to get your original source correct and complete with the phone number so you don't have to do a lookup. Failing that, you could setup an action on dashboard in Tableau tied to clicking a customer phonenumber. That could effectively use the Web Page object to google the phone number. See attached as an example utilizing a URL action when you click on the customer record.
