# Destination numbers

A destination number is the phone number that rings when someone calls one of your Nimbata tracking numbers: typically your main business line, a mobile, a call center, or an on-call team member. You add it once, verify it, and then use it in your call flows.

## Add a destination

1. **Go to Tracking > Destinations**

   Inside the Nimbata app, head to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations) and click the **+ Add** button.

2. **Fill in the destination details**

   - Select the flag of the country your phone number belongs to.
   - Enter the phone number and give it a memorable name.
   - Click **Add Destination**.

   > **Tip:** Optionally, tick **Create a simple call flow for \[number]** before clicking **Add Destination** to simultaneously create a call flow linked to this destination.

   ![Click 'Add Destination'.](https://help.nimbata.com/_astro/01-image_1pb477p.ByggCP7I_Z1CxwX3.webp)

You can add your destination number to a call flow right away. Until the number is verified, the call flow shows **Waiting on destination verification.**, so verify the number next: Nimbata forwards calls to it only once it is verified (see [Verify a destination](https://help.nimbata.com/tracking/destination-numbers#verify-a-destination)).

## Verify a destination

- Before Nimbata can forward calls to a destination number, the number must be verified.
- Verification is a one-time step per destination number.
- Once verified, it stays verified unless you remove it from your account.

### Why verification is required

Telecom regulations in most countries require carriers to confirm that a forwarding destination is a real, reachable phone number before it can receive call traffic. This protects you and your callers from misdirected calls and ensures Nimbata complies with local number regulations.

Nimbata verifies destination numbers in one of two ways, depending on your country and number type.

### Option A: automated verification call

This is the most common method.

1. **Add the destination number**

   - Go to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations).
   - Click **+ Add**.
   - Select the flag of the country the number belongs to.
   - Enter the phone number and give it a name.
   - Click **Add Destination**.

   ![Click Add destination.](https://help.nimbata.com/_astro/01-image_1pb477p.ByggCP7I_Z1CxwX3.webp)

2. **Answer the verification call**

   - Click **Verify**. Nimbata places an automated call to that number within a few seconds.
   - Answer the call and follow the voice prompt, typically pressing a key to confirm.
   - Once confirmed, the number's status updates to **Verified** and you can use it in call flows immediately.

> **Tip:** Make sure someone is available to answer the verification call when you submit it. Missed calls are the most common reason verification stalls.

### Option B: manual verification by the support team

For some countries, toll-free numbers, VoIP lines, and certain number types, automated calling is not available. In those cases, the Nimbata team verifies the number manually.

Submit a support request:

- Click the **?** icon in the top right of your Nimbata dashboard.
- Select **Submit a request**.
- Include the destination number with country code and a note that you need it verified.

The team typically completes manual verifications within one business day.

### Verification statuses

| Status         | What it means                                                                                                                                                                                         |
| -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Pending**    | Verification is in progress. This is normal: it can take a few minutes for an automated call or up to one business day for a manual review.                                                           |
| **Verified**   | The number is active and ready to receive forwarded calls.                                                                                                                                            |
| **Failed**     | The verification call was not answered or was rejected. See [the troubleshooting below](https://help.nimbata.com/tracking/destination-numbers#the-verification-call-wasnt-answered) for how to retry. |
| **Unverified** | The number has been added but verification has not been started yet.                                                                                                                                  |

### Troubleshooting verification

#### The verification call wasn't answered

The automated call goes out within seconds of submitting. If no one was available to answer, the attempt fails silently.

- Go to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations).
- Find the number.
- Click **Re-verify** to trigger a new call, or remove and re-add the number.

#### The number format is wrong

Nimbata requires numbers in the correct national format for the destination country. Common mistakes:

- Entering a number without its country code, or with the wrong country: a US number is `+1` followed by its 10 digits, for example `+1 435 292 9550`. Nimbata saves the number as digits only (`+14352929550`), so spaces in what you type don't matter.
- Selecting the wrong country flag before entering the number.

Remove the number, correct the format, and re-add it.

#### The number belongs to another account

If you see a "destination already exists" error, the number is already registered under a different Nimbata account, possibly a previous trial or a colleague's account. Contact support with the number and they can resolve the conflict.

#### A red banner flashes and disappears with no error message

This is a backend validation failure, usually caused by a formatting issue or a number that is blocked at the carrier level.

- Click the **?** icon and select **Submit a request**.
- Include the destination number with country code, the country it is in, and a screenshot of the error if possible.

#### Verification is showing Pending for more than 24 hours

- Automated verifications should resolve in under five minutes.
- If it has been longer than 24 hours, the verification call likely failed silently.
- Contact support to reset and re-trigger it.

#### The number is a toll-free, VoIP, or non-geographic number

These number types often cannot receive automated verification calls. Submit a support request and mention that it is a toll-free or VoIP line so the team can apply the correct manual process.

### After verification: what's next?

Once your destination number is verified, assign it to a call flow:

1. **Open a call flow**

   Go to [Call handling > Call Flows](https://app.nimbata.com/call-handling/call-flows) and open or create a call flow.

2. **Pick the destination**

   Under the routing step, select your verified destination number.

3. **Save and assign**

   Save the call flow and assign a tracking number to it.

Your setup is complete. Calls to your tracking number now forward to your verified destination.

## Delete a destination

> **Warning:** Destination numbers can be removed only if they are not part of an active call flow. Before attempting to delete a destination number, check its current status. If the status appears as "In use" (as below), follow the steps below.

1. **Check the destination number's status**

   Go to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations) and check whether the number shows **"In use"**.

   ![Check whether the number shows "In use".](https://help.nimbata.com/_astro/01-image_1tsblym.DjHqoiQp_Z1n0yT.webp)

2. **Open the call flow that uses it**

   Go to [Call handling > Call Flows](https://app.nimbata.com/call-handling/call-flows) and click the name of the call flow that includes the destination number you want to delete.

   ![Click on the name of the call flow that includes the destination number you want to delete.](https://help.nimbata.com/_astro/02-image_179lx73.iI380IkT_Z2hfOHF.webp)

3. **Remove the destination number from the call flow**

   Delete the **Dial** section that contains the destination number.

4. **Delete the destination number**

   - Return to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations). The number now shows **"Not in use"**.
   - Select the number and click the **red bin icon**.
   - Click **Remove** on the confirmation message that appears.

You receive a notification confirming the destination number has been removed.
