How Smarty compares
Not all address autocomplete tools are built the same. Smarty is built for addresses that need to show up on a package, not just on a map.

FAQ
Is this just Google Places under the hood?
Not even close. Google Places is built for finding locations and businesses. Smarty is for structured, operational US address entry with verified suggestions formatted to USPS standards, including apartments, suites, PO Boxes, military addresses, and non-USPS locations.
Does autocomplete slow down my form?
No, it’s the opposite, actually. Suggestions start on the first keystroke (unless you configure it differently), so users see relevant options immediately without waiting to finish typing. Responses are optimized for low latency, and the whole product is designed to speed up form completion, not interrupt it. Users typically finish address entry significantly faster and with fewer errors.
Can I use Smarty’s autocomplete alongside my existing verification provider?
Yes. Autocomplete handles the front-end input experience: suggestions and selection. Your verification layer handles post-submission validation. They work independently or together. You don't have to rip anything out. If you’re looking for an even better address verification, Smarty offers US and International Address Verification.
Does autocomplete validate deliverability?
Autocomplete helps users select accurate, real addresses as they type. It reduces entry errors and improves form completion.
If you need deeper deliverability confirmation, such as DPV or additional USPS validation, that happens after submission via US Address Verification.
Many teams use both. Autocomplete improves the user experience at the front end. Verification confirms deliverability and provides additional confidence for shipping, billing, and back-end operations.

What if a new address doesn’t appear?
Newly built addresses can take time to appear in authoritative datasets. If something looks incorrect or missing, our support team can help investigate.
How is pricing calculated?
Autocomplete is billed by lookup volume. Each keystroke request counts as one lookup, regardless of how many suggestions come back. Plans scale based on usage. Most users find their address in 5 keystrokes, so you can delay triggering autocomplete until then to keep your lookup count (and your bill) lower.
