A2P 10DLC Registration
If you plan to use Twilio to send any text messages from 10DLC phone numbers, you’ll need to register your messaging use case (known as a Campaign) in the Twilio Console or with Twilio APIs. Messages from unregistered numbers are subject to filtering and higher unregistered fees, and may ultimately be blocked by telecommunications carriers.
Register for A2P 10DLC via the Twilio Console or API if you have not done so.
According to the Twilio website:
A2P 10DLC refers to a system in the United States that allows businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code (10DLC) phone numbers. Carriers in the US consider all Twilio traffic to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality and lower filtering risk than long code SMS of the past, using the same phone numbers.
See the Twilio website for instructions.
If you send messages to the United States using long code numbers, you have the following registration options based on your Tax ID status, volume, and use case:
- If you have a Tax ID (EIN) and send under 6,000 message segments per day, you should re-register for Low Volume Standard Brands
- If you have a Tax ID (EIN) and send over 6,000 message segments per day, you should re-register for appropriate campaign types within Standard Brands
- If you don’t have a Tax ID (EIN), you should register a Sole Proprietor Brand
See the Twilio guide to compliance for nonprofit and government organizations.
