Move Phone Numbers Between Sub-Accounts in the Same Agency

By Sparkforge Support Team ·Last reviewed May 3, 2026

Use Settings → Phone Integration → Move Numbers to reassign US or Canada numbers between sub-accounts inside the same Sparkforge agency. Sparkforge Phone-to-Sparkforge Phone and same-master Twilio-to-Twilio moves are supported in-app.

Move Numbers reassigns phone numbers from one sub-account to another inside the same agency. The tool lives at Settings → Phone Integration. Supported moves run in-app; everything else needs a different path.

What Move Numbers Supports

Source → Destination	Supported in-app?
Sparkforge Phone ↔ Sparkforge Phone (same agency)	Yes
Twilio ↔ Twilio (same master Twilio account)	Yes
Twilio ↔ Twilio (different master accounts)	No — contact Twilio Support
Twilio ↔ Sparkforge Phone (provider conversion)	No — follow conversion guide
Non US/Canada numbers	No — open a Sparkforge support ticket

Before You Start

Confirm admin access to both source and destination sub-accounts.
Grab the destination Location ID (Sub-account ID) from Settings → Business Profile.
Confirm the current phone provider — Sparkforge Phone or Twilio at the agency level.
Note that A2P registration does not move with the number. Reattach the correct brand and campaign in the destination after the move.

Move the Numbers

Step 1: Open Move Numbers

Go to Agency Settings → Phone Integration. Under Sub-account Settings, click Move Numbers.

Step 2: Pick Source, Destination, and Numbers

Choose the destination sub-account by name or paste the Location ID. Select the phone numbers to move. Review the summary and click Move Numbers.

Step 3: Verify in the Destination

Once the move completes, the numbers appear in the destination sub-account. Re-check:

Forwarding rules
Call recordings and whispers
SMS and call flow assignments
User assignments
A2P brand and campaign attachment

Troubleshooting

Move Numbers Action Is Missing or Fails

Different Twilio masters. Numbers under separate Twilio master accounts cannot move in-app. Contact Twilio Support.
Missing regulatory bundle. Some countries (e.g., AU +61) require an approved Regulatory Bundle and Address SID in the destination before any move. Configure those first.
Provider mismatch. Twilio-to-Sparkforge or Sparkforge-to-Twilio is a conversion, not a move. Follow the dedicated conversion article.
Country not supported in-app. Open a Sparkforge support ticket for non-US/Canada moves.

Frequently Asked Questions

Can I move multiple numbers at once?

Yes. Select multiple numbers in the Move Numbers dialog and submit them together.

Do I need to contact Twilio?

Not for in-app sub-account moves under the same Twilio master account. Cross-master moves and provider conversions need Twilio Support or a Sparkforge support ticket.

Does A2P registration move with the number?

No. A2P is sub-account-level. After the move, attach the number to the correct brand and campaign in the destination sub-account.

Can I move numbers from countries other than the US or Canada?

Not in-app. Open a Sparkforge support ticket for international moves — some countries also require regulatory bundles and address SIDs in the destination.

What happens to call forwarding and recordings after the move?

Number-level settings need to be re-verified in the destination. Check forwarding, recordings, whispers, and any automations that referenced the number.
