Business customers can have multiple phone numbers associated with their [Meta Business Account](https://business.facebook.com/settings/), so they can [add another number for API use](https://developers.facebook.com/documentation/business-messaging/whatsapp/solution-providers/manage-phone-numbers#adding-more-phone-numbers) if they wish. When completing the Embedded Signup flow, your business customers should use a phone number and display name that they want to have appear in the WhatsApp app. We strongly discourage signing up with a test or personal number, or test display name, as are difficult to change. For more detailed information relating to phone numbers and WhatsApp for Business Platform, see [Phone Numbers](https://developers.facebook.com/documentation/business-messaging/whatsapp/business-phone-numbers/phone-numbers). For information on how to migrate an existing registered WhatsApp phone number, see [Migrate Phone Number](https://developers.facebook.com/documentation/business-messaging/whatsapp/solution-providers/support/migrating-phone-numbers-among-solution-partners-via-embedded-signup). ## Instructions for business customers This section is directed towards customers of Embedded Signup and provides guidance about actions they may perform relating to phone numbers. ### Add Phone Numbers to a WhatsApp Business Account There are two methods to add additional numbers to a WhatsApp Business Account (WABA): **\[Recommended]** Go through the embedded signup flow again, select the existing Business Manager & WABA, add the number, and verify it. In the **Business Manager**, go to the **Phone Numbers** tab of **WhatsApp Manager**, and select **Add Phone Number**. When using this option, the Solution Partner has to manually verify the phone number as phone verification is not available in the Business Manager. For this reason, it is recommended that businesses follow the embedded signup flow to add additional numbers. ## Instructions for Solution Partners This section is directed towards Solution Partners and provides instructions for managing customer phone numbers and certificates. ### Getting phone numbers Use the [GET /\/phone\_numbers](https://developers.facebook.com/documentation/business-messaging/whatsapp/reference/whatsapp-business-account/phone-number-management-api#Reading) endpoint to get a list of business phone numbers on a business customer’s WABA. #### Request ``` curl 'https://graph.facebook.com/<API_VERSION>/<CUSTOMER_WABA_ID>/phone_numbers' \ -H 'Authorization: Bearer <CUSTOMER_BUSINESS_TOKEN>' ``` #### Response Upon success: ``` \{ "data": [\ {\ "verified_name": "<VERIFIED_DISPLAY_NAME>",\ "code_verification_status": "<VERIFICATION_STATUS>",\ "display_phone_number": "<DISPLAY_PHONE_NUMBER>",\ "quality_rating": "<QUALITY_RATING>",\ "platform_type": "CLOUD_API",\ "throughput": {\ "level": "<THROUGHPUT_LEVEL>"\ },\ "webhook_configuration": {\ "application": "<WEBHOOK_CALLBACK_URL>"\ },\ "id": "<BUSINESS_PHONE_NUMBER_ID>"\ }\ ], "paging": { "cursors": { "before": "<BEFORE_CURSOR>", "after": "<AFTER_CURSOR>" } } } ``` ### Register phone numbers | | | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------- | | After a successful phone verification from the Embedded Signup flow, registration should succeed with an API call to the [`register` endpoint](https://developers.facebook.com/documentation/business-messaging/whatsapp/reference/whatsapp-business-phone-number/register-api#Creating). For this, provide any `code_method` (`sms` | `voice`). Since the phone number is already verified, you do not need to worry about the registration code. | Alternatively, **you can pre-verify phone numbers** and offer them to your customers in the new Embedded Signup flow. This prevents customers from having to contact you for a one-time password during the onboarding process. See [Pre-Verified Phone Numbers](https://developers.facebook.com/documentation/business-messaging/whatsapp/embedded-signup/pre-verified-numbers). A phone number **must** be registered up to 14 days after going through the Embedded Signup flow. If a number is not registered during that window, the phone must go through to the Embedded Signup flow again prior to registration. ### Get phone metadata The `phone_numbers` endpoint allows you to see the status of a phone number’s display name and other metadata. #### Example request In the following example, use the ID for the assigned WABA. ``` curl -i -X GET "https://graph.facebook.com/<API_VERSION>/<WABA_ID>/phone_numbers ?fields= display_phone_number, certificate, name_status, new_certificate, new_name_status &access_token=<SYSTEM_USER_ACCESS_TOKEN>" ``` To find the ID of a WhatsApp Business Account, go to [**Business Manager**](https://business.facebook.com/) > **Business Settings** > **Accounts** > **WhatsApp Business Accounts**. Find the account you want to use and click on it. A panel opens, with information about the account, including the ID. #### Example response ``` \{ "data": [\ {\ "id": "1972385232742141",\ "display_phone_number": "+1 631-555-1111",\ "last_onboarded_time": "2023-08-22T19:05:53+0000",\ "certificate": "AbCdEfGhIjKlMnOpQrStUvWxYz",\ "new_certificate": "123AbCdEfGhIjKlMnOpQrStUvWxYz",\ "name_status": "APPROVED",\ "new_name_status": "APPROVED",\ }\ ] } ``` ### Response parameters | Name | Description | | ----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `name_status` | The review status of the current display name request. Available Options:

This field returns data only if a display name change was requested. | | `certificate` | Returns the current certificate for that phone number. | | `new_certificate` | The certificate of a new display name, after a display name change has been approved. This field returns data only if a display name change request was approved and is available until the phone number has been registered with the new certificate. | ### Get phone’s OTP status To see if a phone number has been verified via OTP (one-time password), check that number’s `code_verification_status` field. First, make a `GET` call to the `/ Phone Numbers](https://developers.facebook.com/documentation/business-messaging/whatsapp/reference/whatsapp-business-account/phone-number-management-api#Reading) endpoint to get a phone number’s ID. See [Retrieve Phone Numbers](https://developers.facebook.com/documentation/business-messaging/whatsapp/business-phone-numbers/phone-numbers#get-all-phone-numbers) for usage details. ### Filter phone numbers by account mode You can query phone numbers and filter them based on their `account_mode`. For the request, you can use the parameters listed below. #### Request parameters | Name | Description | | ---------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `field` | Contains the field being used for filtering. In this example, you should use `account_mode`. | | `operator` | Contains how you want to filter the accounts. In this example, you should use `EQUAL`. | | `value` | Contain what account mode you are looking for. Supported Values:
`SANDBOX`: The account is unverified.
`LIVE`: The account is not eligible for the unverified trial experience or it has upgraded to a verified account. | #### Example request In the following example, use the ID for the assigned WABA. ``` curl -i -X GET "https://graph.facebook.com/<API_VERSION>/<WABA_ID>/phone_numbers ?filtering=[{\ "field":"account_mode",\ "operator":"EQUAL",\ "value":"SANDBOX"}] &access_token=<SYSTEM_USER_ACCESS_TOKEN>" ``` #### Example response ``` \{ "data": [\ {\ "id": "1972385232742141",\ "display_phone_number": "+1 631-555-1111",\ "verified_name": "John’s Cake Shop",\ "quality_rating": "UNKNOWN",\ }\ ], "paging": { "cursors": { "before": "abcdefghij" "after": "klmnopqr" } } } ``` ## Learn More [Phone numbers: WhatsApp for Business Platform Overview](https://developers.facebook.com/documentation/business-messaging/whatsapp/business-phone-numbers/phone-numbers) [Phone numbers: Migrate an existing registered number](https://developers.facebook.com/documentation/business-messaging/whatsapp/solution-providers/support/migrating-phone-numbers-among-solution-partners-via-embedded-signup) Reference: [WhatsApp Business Account](https://developers.facebook.com/documentation/business-messaging/whatsapp/reference/whatsapp-business-account/whatsapp-business-account-api) Did you find this page helpful? ![Thumbs up icon](https://static.xx.fbcdn.net/rsrc.php/yR/r/OEXJ0_DJeZv.svg) ![Thumbs down icon](https://static.xx.fbcdn.net/rsrc.php/yb/r/qKPgNVNeatU.svg) ON THIS PAGE Basics Instructions for business customers Add Phone Numbers to a WhatsApp Business Account Instructions for Solution Partners Getting phone numbers Request Response Register phone numbers Get phone metadata Example request Example response Response parameters Get phone’s OTP status Filter phone numbers by account mode Request parameters Example request Example response Learn More ***
