Google Maps Platform Address Validation API checks address components, standardizes addresses for mailing and identifies the best known geocode.
What Google Maps Platform Address Validation API is
Google Maps Platform Address Validation API checks address components, standardizes addresses for mailing and identifies the best known geocode. A response includes parsed address details, a geocode and a deliverability verdict. For ecommerce checkout, Google describes combining it with Place Autocomplete and a Google Map, with prompts that let customers fix, confirm or accept an address. The API supports batch validation and address standardization, but not address autocomplete. It is available globally, although coverage and address data quality differ by country; residential and commercial metadata is populated only for countries listed in the coverage table. For US and Puerto Rico addresses, requests can optionally use USPS CASS processing. Authenticated requests use HTTP POST, and HTTPS is required when using API keys or sending user data. Validation methods and feedback methods each have a documented limit of 6,000 queries per minute. Policies generally restrict pre-fetching, caching or storing results, though Place IDs may be stored indefinitely. Map displays require a Google Map and attribution; attribution is also required without a map.
