Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nSend an address validation request by issuing a POST request to one of the\nfollowing endpoints:\n\n- [validateAddress](/maps/documentation/address-validation/reference/rest/v1/TopLevel/validateAddress) (REST)\n- [ValidateAddress](/maps/documentation/address-validation/reference/rpc/google.maps.addressvalidation.v1#google.maps.addressvalidation.v1.AddressValidation.ValidateAddress) (gRPC)\n\n| **Note:** This documentation uses REST for its examples, but the approach is similar with [gRPC](https://www.grpc.io/).\n\nYour request should also pass a [JSON request body](/maps/documentation/address-validation/reference/rest/v1/TopLevel/validateAddress#request-body) to the request that\ndefines the address to validate. The following request body contains one field\nand three subfields: \n\n```json\ncurl -X POST -d '{\n \"address\": {\n \"regionCode\": \"US\",\n \"locality\": \"Mountain View\",\n \"addressLines\": [\"1600 Amphitheatre Pkwy\"]\n }\n}' \\\n-H 'Content-Type: application/json' \\\n\"https://addressvalidation.googleapis.com/v1:validateAddress?key=\u003cvar translate=\"no\"\u003eAPI_KEY\u003c/var\u003e\"\n```\n\nYou can also omit `locality` and specify it as an element in\nthe `addressLines` array: \n\n {\n \"address\": {\n \"regionCode\": \"US\",\n \"addressLines\": [\"1600 Amphitheatre Pkwy\", \"Mountain View, CA, 94043\"]\n },\n }\n\nThe APIs Explorer lets you make live requests so that you can get familiar with\nthe API and the API options: \n[Try it!](#try_it)\n\nAddress request fields\n\nThe request body consists of a single field:\n\n- `address` --- a field of type [`PostalAddress`](/maps/documentation/address-validation/reference/rest/v1/TopLevel/validateAddress#postaladdress), which must contain at least one entry in `addressLines`.\n\nWhen sending the `address` field to the Address Validation API, you need only\nsupply one field: `addressLines`. However, the simplest address request\nshould contain the following subfields:\n\n- `regionCode` --- Recommended. This is an optional field, but if omitted, the Address Validation API infers the region from the address. However, for best results, include the `regionCode` if you know it. For the list of supported regions, see [supported regions](/maps/documentation/address-validation/coverage).\n- `addressLines` --- Required. An array with addresses describing the lower structure of the address.\n\n|----------------------------------------------------------------------------------------------------------------------------------------------|\n| See [PostalAddress](/maps/documentation/address-validation/reference/rest/v1/TopLevel/validateAddress#postaladdress) in the reference guide. |\n\nUSPS CASS™ option\n\nThe United States Postal Service® (USPS®)^[1](#fn1)^ maintains the\n[Coding Accuracy Support System (CASS™)](https://postalpro.usps.com/certifications/cass) to support and certify\naddress validation providers.\n| **Note:** The Address Validation API is confirmed as a CASS-Certified™ service. This means the service is confirmed for its ability to fill in missing address information, standardize it, and update it to the most current and accurate address.\n\nFor US and PR regions only, you can enable CASS processing by setting\n`enableUspsCass` to `true` in the request body. For best results when using\nCASS, provide an address that includes the street and street number along with\nthe city, state, and ZIP code: \n\n {\n \"address\": {\n \"regionCode\": \"US\",\n \"locality\": \"Mountain View\",\n \"administrativeArea\": \"CA\",\n \"postalCode\": \"94043\",\n \"addressLines\": [\"1600 Amphitheatre Pkwy\"]\n },\n \"enableUspsCass\": true\n }\n\n| **Note:** If you don't require CASS processing, or if you are validating addresses outside of the US and PR regions, Google does not recommend enabling this feature.\n\nTry it!\n\nThe APIs Explorer lets you make sample requests so\nthat you can get familiar with the API and the API options.\n\n1. Select the API icon api\n on the right side of the page.\n\n2. Optionally edit the request parameters.\n\n3. Select the **Execute** button. In the dialog, choose the account\n that you want to use to make the request.\n\n4.
