Validate Unique Mailing Address

Is there a way to Validate mailing addresses as unique? If not, is it possible?

William Beem

I use Fluent Forms in registration to perform that task. I accept payment with it and that gets validated first. After payment is confirmed, Fluent Forms checks to see if there is an existing email address associated with a WordPress user account. If so, it alerts the user on the form.

So I know it can validate email as unique. I was wondering if it could ever validate a physical mailing address as unique.

Selina WalkerΒ To validate postal addresses inΒ Fluent Forms,Β you canΒ utilize the Address Autocomplete feature,Β which usesΒ Google MapsΒ for address suggestions and simplification of the form-filling process.Β This feature, available in the Pro version, allows users to start typing their address, and the form will automatically populate the remaining fields.Β

William BeemΒ Thank you, but that's not exactly what I'm looking for. I already have the API setup for AutoComplete, what I'm curious about is if it can validate a postal address as unique-meaning someone can only fill out the form with that postal address once.
