With Smarty, you always validate against fresh address data. Our reference datasets are updated monthly to ensure you have access to the most current address information available.
There are many ways for address verification to generate high returns. Reduce shipping costs and fraud. Increase billing collections and reporting accuracy. The list goes on. Want to see how much it can save you just in mailing/shipping? Try our mailing/shipping calculator.
You can get it cheaper on the front end but more costly on the back end. Also, some providers play “credits” shenanigans, making it difficult for you to understand your actual costs. Smarty's pricing is clear.
It’s a "let's-be-transparent" and “get-what-you-pay-for” kind of thing with significant consequences following implementation.
Be aware that cheaper will mean less accurate and higher operational costs. Smarty gives you global coverage, lightning-fast address lookups, and top-tier accuracy—so you save more in the long run by avoiding failed deliveries, wasted postage, and bad data costs. Smarty is your Goldilocks solution; we’re not the most expensive and we’re not the cheapest, but we are the best value and drive the best ROIs.
To stop worrying about cost, do a free-trial comparison between Smarty and the other guys. We’re begging you. Then calculate the operational savings that better data gives your company. Smarty is the safe and easy ROI decision.

Need high-volume address lookups or have questions? Our sales team is happy to help you find the best option.
Yes! All International Address Verification subscriptions include access to Smarty's International Postal Code API. Speak with an address expert to confirm whether or not you have access, or to add it.
The International Postal Code API is ideal when you only need to verify and standardize international postal codes or convert between postal codes and their corresponding administrative areas (states, provinces, or regions) and localities (cities). It's a fast, lightweight way to work with postal code data without performing full address verification.
Learn more: View the overview, go deep on how postal code APIs are used, explore the documentation, or try the tool in the interactive playground.
Rest assured that the APIs work seamlessly together and are both supported with stellar SDKs filled with examples and sample code to make integration a snap.
With the free trial, you can experience the full version whether you’re verifying lists or testing integration of Smarty’s API into your systems and processes. Free trials come with 100 address lookups. If you need more, just contact our sales team.
