Validate a single US address (Deprecated)

⚠️

Address Validation is moving to a single endpoint. We've combined Domestic and International Address Validation into one Address Validation endpoint. If your connection uses the Domestic scope, switch before August 31, 2026 — after that, calls to this endpoint will return an error. See the migration guide for details.

Deprecated. Use POST /2024-09/addresses/validations with country_alpha2: "US" instead.

Required authorization scope: public.address_validation_domestic:write

Note: This endpoint requires an advanced scope. You can enable advanced scopes when creating or editing your API connection.

Note: Calls to this endpoint count towards your API usage allowance. You can monitor your current usage in the Subscription section of your account.
