Google Maps Platform Address Validation API review
A Google-hosted validation API with detailed address, geocoding, and deliverability outputs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Google Maps Platform Address Validation API is a paid developer service for applications that need to check postal addresses during checkout, delivery, or customer-data workflows. It accepts addresses through REST or gRPC requests, validates individual components, suggests corrections and completion, standardizes mailing formats, and returns geocoding and deliverability information where available. The API supports selected countries and regions worldwide, with CASS support for addresses in the United States and Puerto Rico.
Pricing is usage-based and billed monthly. Address Validation Pro costs $17 per 1,000 successful requests and includes 5,000 free monthly billable events. Address Validation Enterprise costs $25 per 1,000 billable events and includes 1,000 free monthly billable events; it is used for Autocomplete (New) sessions that terminate in address validation. Pay-as-you-go pricing applies to both plans, while volume pricing applies based on monthly usage. Pricing also varies by region, monthly volume, and SKU, with a separate pricing list for India. Some countries, including India, are marked preview in the coverage documentation.
Its main strength is the depth of the validation response rather than simple address acceptance. Applications can receive correction suggestions, standardized mailing formats, geocodes, address precision, deliverability verdicts, validation status, and validation feedback submission. Batch validation is supported, and the service fits teams that want API-based checks within a Google Maps Platform workflow. It is less suitable for teams seeking built-in autocomplete or a narrower, fixed-price address-checking service. Developers should also consider regional coverage and the limits of CASS support when address formatting requirements are specific to the United States or Puerto Rico.
