# Verify a phone number

POST https://api.getdial.ai/api/v1/auth/verify-number
Content-Type: application/json

Submits the SMS code from [Register a phone number](#operation/registerNumber).
On success the account is created, an API key is issued, and a first phone
number is provisioned — the response is identical to the sign-in outcome of
[Verify a sign-up code](#operation/verifySignup). **The API key is returned
only once — store it immediately.**

If provisioning fails you receive a `502` and may retry this call with the
same `registrationId`; the phone number stays verified, so no new code is
needed.

Note that `phoneNumber` in the response is the **Dial** number provisioned
for the account, not the number you just verified.

## Request

### Body (application/json)

- `registrationId` (string, required)
- `code` (string, required) — The 6-digit code from the SMS.

## Response

### 200

Verified, account created.

- `apiKey` (string, optional, nullable) — Your API key. Shown once, when the account is created.
- `accountId` (string, optional)
- `created` (boolean, optional) — True when this call created the account.
- `phoneNumber` (string, optional, nullable) — The Dial number provisioned for the account, if any. This is not the phone number used to register.
- `phoneNumberId` (string, optional, nullable)
- `message` (string, optional)
