How to Buy a Twilio Number That Syncs to Sparkforge

By Sparkforge Support Team ·Last reviewed May 3, 2026

If you connected your own Twilio account, any number you buy in the matching Twilio sub-account appears under Sparkforge Settings > Phone Numbers automatically. Match the Account SID first, then purchase.

When you bring your own Twilio account, numbers purchased inside the correct Twilio sub-account flow into Sparkforge automatically. The key is making sure the sub-account you buy in matches the one connected to your Sparkforge location.

Before you start

  • Active Twilio account already linked to a Sparkforge location
  • Access to Sparkforge Agency view to confirm the Account SID
  • Twilio sub-account permissions to purchase numbers

Step 1: Find the correct Twilio Account SID in Sparkforge

  1. Open Sparkforge Agency View.
  2. Go to Settings > Phone Integration > Sub-account Settings.
  3. Copy the Account SID for the location you are buying for.

Step 2: Switch into that Twilio sub-account

  1. Log in at twilio.com/login.
  2. Open the account switcher and paste the Account SID.
  3. Confirm you are now inside the matching sub-account before purchasing.

Step 3: Buy the number

  1. In Twilio, go to Develop > Phone Numbers > Manage > Buy a Number.
  2. Select the country in the dropdown (e.g., Australia).
  3. If you need a mobile number, click Advanced Search and uncheck Local number.
  4. Pick the capabilities you need (Voice, SMS, MMS) and complete the purchase.

Step 4: Verify the number in Sparkforge

Return to your Sparkforge location and open Settings > Phone Numbers. The new Twilio number should appear in the list within a minute. If it doesn't, you almost certainly purchased it in the wrong sub-account.

Common issues

  • Number doesn't appear: wrong sub-account. Re-check the Account SID match.
  • No mobile numbers in results: Advanced Search with Local number still checked.
  • SMS doesn't send after purchase: A2P 10DLC registration may be required for US numbers.

Frequently Asked Questions

Will my new Twilio number appear in Sparkforge automatically?
Yes, as long as you purchased it inside the Twilio sub-account that matches your Sparkforge location's Account SID. It shows up under Settings > Phone Numbers.
How do I confirm I'm in the right Twilio sub-account?
Copy the Account SID from Sparkforge Agency View > Settings > Phone Integration > Sub-account Settings, then paste it into Twilio's account switcher to jump directly to the correct sub-account.
Why don't I see mobile numbers when searching?
Twilio defaults to local landline numbers. Click Advanced Search and uncheck the Local number option to surface mobile inventory.
Do I need to buy numbers through Twilio if I use Sparkforge?
No. Most users buy numbers directly inside Sparkforge. Buying in Twilio only applies when you've connected your own Twilio account instead of using the built-in option.
