What is carrier registration?
A2P 10DLC is how U.S. carriers verify businesses that text from local 10-digit numbers. Registration tells carriers who you are and what you send. This improves deliverability and reduces filtering. If you text from toll-free numbers, you’ll complete Toll-Free Verification (a separate process).Who needs to register?
- Any business texting U.S. recipients from local (10DLC) numbers in MessageDesk.
- Toll-free numbers require toll-free verification per number.
Businesses or organizations texting only within Canada (never sending to U.S.-based numbers) are currently exempt from carrier registration.
How long does carrier registration take?
- Businesses with an EIN: typically 5 to 7 business days.
- Toll-Free Verification: typically 2 to 3 weeks.
Timelines vary if carriers can’t verify your information on the first pass.

Options:- Form an LLC, Inc, or Corp (services like LegalZoom can set this up in a few business days), then register under the Business (EIN) path above.
