Moving US Phone Numbers from Twilio to LC Phone

Migrate your US phone numbers from your Twilio account to GHL Customer Care's LC Phone system and manage calling, SMS, and messaging registration in one platform.
What You'll Learn

This guide walks you through migrating US local and toll-free phone numbers from your Twilio account to GHL Customer Care's LC Phone system.

You'll learn what information to gather before migration, how to submit a migration request, what moves with the phone number, and how to verify calling, SMS, and messaging registration after the cutover.

1What is Phone Number Migration?

Phone number migration transfers control of a US local or toll-free phone number from one phone system provider to another. When you migrate a phone number from your Twilio account to GHL Customer Care's LC Phone system, the number becomes managed by LC Phone for all future calling, SMS, and messaging functionality.

This migration process changes which platform manages the number but does not automatically move historical data, call recordings, or messaging registration from your Twilio account.

GHL Customer Care Support coordinates the migration end-to-end after you provide the required account and phone number identifiers.

2Key Benefits

Migrating your US phone numbers from Twilio to LC Phone centralizes phone management inside GHL Customer Care and provides access to native LC Phone features.

Centralized Phone Management — Manage calling and messaging directly inside GHL Customer Care without switching between platforms.
Native GHL Customer Care Features — Use LC Phone functionality such as call tracking, workflows, and messaging automation.
Simplified Billing — Manage phone usage and number charges through GHL Customer Care.
Streamlined Support — Troubleshoot LC Phone issues through GHL Customer Care Support.

3What Moves with the Phone Number?

Moving a phone number changes which phone system manages the number. It does not automatically migrate historical phone-system data from the original Twilio account.

AssetMigration Behavior
Phone numberMoves to LC Phone
Future calls and SMSRoute through LC Phone after cutover
Historical Twilio recordingsDo not automatically migrate
Historical voicemailsDo not automatically migrate
Contacts and ConversationsAre not transferred as part of phone number migration
A2P / Toll-Free registrationMust be verified after migration and may require re-registration
Important

A2P registration may need to be completed again after moving from your own Twilio account to LC Phone. Existing A2P registration from Twilio does not automatically migrate to LC Phone. After migration, complete or verify A2P registration in GHL Customer Care and confirm each applicable US local number is associated with the correct approved Campaign before resuming A2P messaging.

Toll-Free Numbers

After migration, confirm the number's Toll-Free Verification status before resuming messaging. Verification status should not be assumed to transfer automatically.

4Before the Migration

Preparing the destination location and preserving information you may need later reduces disruption during the cutover.

Checklist Item
Confirm the destination Sub-account ID

Identify the GHL Customer Care Sub-account ID (Location ID) where the phone number will reside after migration.
