Foursquare vs Smarty Address Verification

Foursquare provides location intelligence tools for marketers, developers, analysts, and machine learning engineers. Attribution measures advertising impact across media plans and platforms. Audience builds customizable targeting groups from real-world behaviors, and Proximity supports real-time geo-contextual targeting with custom geofences. Places APIs supply real-time place data for applications and nearby venue discovery.

For spatial analysis, Spatial Workbench brings SQL workbooks, geospatial computing, dashboards, and interactive maps into a browser workspace. It uses pre-provisioned MotherDuck instances and builds maps with Kepler.gl. Foursquare Studio connects to Snowflake and BigQuery, plus QGIS, Grafana, and kepler.gl. It also offers REST API and Python library access, and supports importing and exporting CSV, GeoJSON, Shapefiles, and Vector Tiles. Places API charges by volume on a pay-as-you-go basis, with up to 10,000 free calls on Pro endpoints. Foursquare has free plans, a 30-day trial, and paid plans from $25/mo. The listed platforms are API and web; the company was founded in 2009.

Smarty Address Verification checks, standardizes, and validates US addresses against address data. It analyzes address components and reports what changed and why, including validation down to apartment or suite numbers and up to 55 metadata points. Smarty says its 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, by bulk upload, or through an API, including no-code bulk verification. SmartyKey is a persistent identifier intended to help identify duplicates and merge datasets. Listed integrations include Zapier, Microsoft Excel, Google Sheets, QGIS, and JavaScript. The Zapier action handles up to 100 US addresses per batch and requires an active product license. Smarty lists USPS CASS and AICPA SOC 2 certifications and HIPAA compliance. The 42-day trial includes 1,000 lookups without a credit card. The Professional plan costs $552 a year.
