Summary

Smarty Address Verification checks, standardizes and validates US addresses against address data. It analyzes address components and reports what changed and why, with validation down to apartment and suite numbers and up to 55 metadata points. Smarty says US coverage includes more than 210 million addresses, including over 20 million non-postal addresses; international verification covers 250 countries and territories. Addresses can be checked individually, in bulk or through an API, including no-code bulk verification. SmartyKey is a persistent identifier intended to help detect duplicates and merge datasets. Listed integrations include Zapier, Microsoft Excel, Google Sheets, QGIS and JavaScript. The Zapier action handles up to 100 US addresses in a batch and requires an active license for that action. Smarty lists USPS CASS certification, AICPA SOC 2 certification and HIPAA compliance. The product starts at $17/mo and has a 42-day trial with 1,000 lookups and no credit card required. Its Professional plan costs $552.00 per year.
