How to add your first tracking number(s)

A tracking number is a unique phone number used to attribute calls to specific marketing campaigns, channels, or activities. This guide walks you through acquiring your first number and connecting it to your business.

Best for: New users setting up their Nimbata account for the first time.

Step 1. Start the setup

Go to Tracking > Numbers and click + Add.

Step 2. Choose your source

Select where you want to place your tracking number:

All Online Sources - tracks calls across multiple channels (Google Ads, Organic, Referral, etc.) using dynamic number insertion. Nimbata will ask you to determine a pool size in the next step.
Specific Online Channel - a single number dedicated to one source, such as Google Business Profile or a landing page.
Somewhere Else - for offline sources like billboards, print ads, or business cards.

Click Next on the channel configuration page to continue.

Step 3. Pick your numbers

Choose your prefix (State/City for US; City for EU/UK/AU), select the numbers you want from the list, and click Finish.

Choosing a pool size (All Online Sources only): Nimbata will prompt you to set a pool; the collection of numbers assigned to website visitors.

Click Get from Google to let Nimbata sync with your analytics and recommend a size automatically, or use the built-in calculator if you'd prefer to enter your peak hourly visitors manually.

Step 4. Add a destination number

Go to Tracking > Destinations and click + Add. Select your country, enter the phone number where calls should ring, give it a name, and click Add Destination.

SHORTCUT: Tick Create call flow during this step to automatically set up call routing for your new numbers at the same time.

🎉 Your tracking numbers are ready. To start receiving calls, make sure your numbers are assigned to a call flow.
