Here is what that costs
Figures from the USPS Office of Inspector General. Every one of those pieces was printed, paid for and posted before anyone knew the address was wrong. Validating at the point of entry is the only place the problem is cheap to fix.

FAQ
Do I need a paid Smarty account?
You will need a Smarty account. Their US Address Verification plan includes a 42-day free trial with 1,000 lookups and no credit card required, after which a paid plan is needed.
The plugin uses two Smarty APIs: US Street Address for validation and US Autocomplete Pro for suggestions as you type. Each is a separate subscription in your Smarty dashboard. With only the Street API the plugin still works, and customers type their address manually rather than picking from suggestions.
Does it work with existing forms?
Yes. It automatically enhances all Gravity Forms address fields, with no coding required.
Will it slow down my site?
No. The script loads asynchronously and only runs on pages with address fields.
How many sites can I use it on?
Unlimited. One licence covers every site you build.
What happens when my licence expires?
The plugin keeps working. What stops is updates and support. Renewing at any point restores both.
Does it support international addresses?
No. Address Validation covers US addresses only.
