# Start a verification

`POST /v1/accounts/{accountId}/gmb-verifications`

Starts a verification for the location. This is a mutating action: depending on `method`, Google mails a postcard, places a call, or sends an SMS/email to the business. Submit the resulting code with POST /gmb-verifications/{verificationId}/complete. Use POST /gmb-verifications/options first to discover which methods are eligible.
