Twilio 10DLC Registration
All landline 10-digit long code (10DLC) phone numbers that send text messages to mobile phones in the US must be registered for Application-to-Person (A2P) messaging. Twilio 10DLC Registration works like this:
- Each Brand (end-customer) must be registered with TCR.
- Each Brand must register a Campaign type (use case) with TCR.
- Each Campaign must be associated with a Messaging Service. One campaign per messaging service.
- All lines associated with a Messaging Service will inherit its Campaign.
Twilio offers 10DLC registration through the Trust Hub (in the Twilio Console) and via API.
