# Numbers

> Add, sync, and register WhatsApp Cloud API phone numbers for your project

**Numbers** lists the Cloud API phone numbers on the WhatsApp Business Account connected to this project. Open **WhatsApp** in the project sidebar, then select **Numbers**.

## Prerequisites

* WhatsApp connected on [Overview](/docs/outreach/whatsapp) (hub ready)
* Permission to manage WhatsApp numbers (add, sync, default, calling, and registration)

Until the hub is connected, this tab shows **Phone numbers unavailable**. Use **Go to Overview**.

## Add or sync a number

<Steps>
  <Step title="Open Numbers">
    Under **Outreach**, select **WhatsApp**, then **Numbers**.
  </Step>

  <Step title="Add or sync">
    Select **Add number** and complete Meta Embedded Signup on the **same** Business Portfolio and WABA already linked to this project. Or add the number in Meta Business Manager, then select **Sync from Meta**.
  </Step>

  <Step title="Finish registration">
    If status is not **CONNECTED**, select **Complete registration** on that row. Enter a two-step PIN when Meta asks for it.
  </Step>

  <Step title="Set the default">
    Select **Set as default** on the number that should send by default (broadcasts and outbound).
  </Step>
</Steps>

<Check>
  The row shows status **CONNECTED**, quality, messaging limit, and (when ready) calling chips. The default number is marked **Default**.
</Check>

Numbers on a **different** WABA need a new project, or disconnect and reconnect on Overview.

## Calling per number

Use the **Calling** toggle on a CONNECTED number after registration is complete.

WhatsApp voice calling needs a messaging limit of **2,000+** unique recipients in 24 hours and a Meta-supported country. Below that limit, messaging still works; calling stays unavailable. See [Settings](/docs/outreach/whatsapp/settings) for calling status and inbound voice setup.

<Note>
  Incomplete registration blocks sending and calling. Finish **Complete registration** before you broadcast or enable calling.
