## Description

The maximum number of phone numbers allowed by Meta has been reached for your WABA and no additional WhatsApp Senders can be onboarded in this account. See [Meta's documentation](https://developers.facebook.com/docs/whatsapp/cloud-api/phone-numbers/#registered-number-limits) for more information.

### Possible Causes

- Your Meta Business Portfolio is not yet verified. Meta restricts unverified businesses to 2 phone numbers across all WABAs.
- You have not sent enough WhatsApp messages with your existing WhatsApp Senders or your existing WhatsApp Senders are not high quality.
- You have reached the maximum number of phone numbers that Meta allows without a support ticket.

### Possible Solutions

- Use Meta's [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager) to delete unused phone numbers and their corresponding WhatsApp Senders.
- If you have created multiple WhatsApp Senders at once, send messages on existing WhatsApp Senders before creating additional ones to allow Meta's systems to automatically increase your phone number limit.
- Use a different Twilio account or subaccount with a different WABA to create your WhatsApp Sender.
- If you have access to Meta's [Direct Support](https://business.facebook.com/direct-support) system, open a ticket directly with Meta to increase your phone number limit. Otherwise, [open a ticket](http://help.twilio.com) with Twilio.
