How to Move US Numbers from Twilio to Sparkforge Phone

Move US local or toll-free numbers out of a Twilio account and into a Sparkforge Phone sub-account. The number lives natively inside Sparkforge afterward, so SMS, voice, call tracking, and automation all work without a separate Twilio integration.

Before you start

• You have owner-level access to the client's Twilio account.
• You know the Location ID of the destination Sparkforge sub-account.
• You have submitted a request to Sparkforge Support to receive the Gaining Sub-account SID (the Sparkforge Phone Twilio sub-account SID for that location).
• For international numbers, regulatory bundles and addresses are already approved in Twilio.

Note: This article covers US local and toll-free numbers only. For international numbers, see the international migration guide.

Why move numbers into Sparkforge Phone

• Centralizes communication inside Sparkforge.
• Enables call tracking, automation, and SMS workflows natively.
• Simplifies billing and number management.
• Faster troubleshooting through Sparkforge Phone infrastructure.

What is Sparkforge Phone

Sparkforge Phone is the platform's built-in phone system, operating through a Twilio ISV connection. Once a number lives inside Sparkforge Phone, it is fully managed in-platform with no separate Twilio integration to maintain.

Step 1: Get the Gaining Sub-account SID

1. Open the destination Sparkforge sub-account.
2. Note the Location ID.
3. Submit a Sparkforge Support ticket requesting the Gaining Sub-account SID for that Location ID.

Step 2: Submit a ticket to Twilio

Once Sparkforge Support has provided the Gaining Sub-account SID, open a Twilio Support ticket from the client's Twilio account.

Sample Twilio ticket

Subject: Request to Move Phone Number(s) to New Sub-account

Priority: P3 - General

CC: migration@sparkforgehq.com

Message:

Hi Twilio Support, I would like to move the following phone numbers to a new sub-account: [paste numbers].

Losing sub-account SID: [your current Twilio sub-account SID].

Gaining sub-account SID: [SID provided by Sparkforge Support].

Time-frame: ASAP. This migration is essential for business continuity. Please process at your earliest convenience.

Twilio reviews the request and replies via email. If anything stalls, contact Sparkforge Support.

Final checklist

• Only the Twilio account owner can authorize the migration.
• For international numbers, complete regulatory bundles and addresses in Twilio first.
• Average migration time is 24-72 hours, depending on Twilio processing.
• Always CC migration@sparkforgehq.com on the Twilio ticket so Sparkforge can coordinate.
