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 (and verify it, if Nimbata asks you to), then use it in your call flows.

Add a destination

  1. Go to Tracking > Destinations

    Inside the Nimbata app, head to TrackingDestinations 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.

    The Add Destination page: pick the country, enter the number and its name, then click Add Destination (1).

    Nimbata takes you back to the list, where the new number appears. If something is wrong, the reason shows under the form instead.

    Some destinations, such as numbers in certain countries, cost more per call. For those, Nimbata first asks you to confirm, showing the rate per call: click Confirm to add it. Accounts on a trial, or with an overdue payment, can’t add these numbers.

You can add your destination number to a call flow right away. If the number needs verifying, the call flow shows Waiting on destination verification. until it is, and publishes itself once the number is verified (see Verify a destination).

Verify a destination

  • Nimbata asks you to verify a destination number while your account has no active subscription, for example during a trial. Until it is verified, Nimbata does not forward calls to it.
  • With an active subscription, new destination numbers are verified automatically, and so is a number already verified elsewhere in your account.
  • 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

Verifying confirms that the number is real and that you can reach it, before Nimbata forwards calls to it.

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 TrackingDestinations.
    • Click Add.
    • Select the flag of the country the number belongs to.
    • Enter the phone number and give it a name.
    • Click Add Destination.

  2. Get the verification code

    • In the Is Verified column, click Verify next to the number.
    • Choose how to receive the code: Call places an automated call to that number within a few seconds, SMS sends a text.
    • Answer the call (or read the text) and enter the 5 digit code you received, then click Submit. A code is valid for 10 minutes, and you can ask for up to 4 codes every 10 minutes.
    • Once confirmed, the number shows a green check under Is Verified and you can use it in call flows immediately.
    Click Verify next to the number, then choose Call (1) or SMS to get your code.

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 (the Verify pop-up has a Submit a request link for this too):

  • 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.

If you are an agency and can’t verify a client’s destination yourself, send us a request and we can verify it manually for you. The team only verifies the numbers named in a request.

The team typically completes manual verifications within one business day.

Verification statuses

In TrackingDestinations, the Is Verified column shows a green check for a verified number and a Verify button for one that is not.

A destination is either verified or not: there is no pending or failed state. In a call flow, a destination that still needs verifying carries a needs verification badge. In a CSV export of your destinations, the column reads Yes or No.

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.
  • Find the number.
  • Click Verify to trigger a new call (or an SMS), or remove and re-add the number. If you have asked for 4 codes in the last 10 minutes, wait a few minutes first.

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, with the country code and no + (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.

“This destination already exists”

  • The number is already a destination in this project: find it in the list instead of adding it again.
  • If the message adds that it has not been verified yet, verify the existing destination from TrackingDestinations.
  • If you can’t find it in the project, it may be 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.
  • “You cannot use a tracking number as a destination” means the number is one of your Nimbata tracking numbers: use your business line instead.

Add Destination shows an error you don’t understand

Add Destination shows the reason under the form. If it only says This destination could not be added. Please try again., the cause is usually 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.

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 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

You can remove a destination number even while a call flow uses it. Nimbata shows you what happens to each call flow first.

  1. Find the destination

    Go to TrackingDestinations. The Call Flow column shows In use for a number a call flow uses.

    Destination Numbers

    Where incoming calls are sent when someone dials a tracking number.

    DestinationFriendly NameCall FlowIs Verified
    (415) 555-0110Main officeIn use1
    (415) 555-0119Emergency lineIn use
    A destination that a call flow uses shows In use (1) in the Call Flow column.

  2. Remove it

    Select the number and click the red bin icon (Remove destination).

  3. Check what happens to your call flows

    If a call flow uses the number, the confirmation lists each one and what happens to it:

    • Stays published with its other destinations: the flow keeps working with the destinations it has left.
    • Removed from call flow (or from a draft): the number is taken out of that flow.
    • Becomes a draft until it has a new destination: this was the flow’s only destination, so its tracking numbers stop receiving calls until you give it a new one.

    When tracking numbers would stop receiving calls, type delete to confirm. Otherwise, click Remove.

You receive a notification confirming the destination number has been removed. A call flow that became a draft publishes itself again once you add a new destination to it.
