FAQs about 10DLC
10DLC numbers have a local prefix. Toll-free numbers have a standard prefix like 888 or 833.
10DLC numbers are also a way for businesses to send over dedicated application-to-person routes for business messaging. There are restrictions and guidelines for what you can send over A2P 10DLC numbers.
Sending messages over 10DLC numbers can be less expensive than toll-free or short codes, for that matter.
While there is a verification process for both number types, the approval process for a 10DLC number can take longer to complete than toll-free number.
A sole proprietor 10DLC registration is for senders (in the US and Canada) that do not have a business Tax ID like a US EIN or a Canadian Business Number. This often applies to individuals who are sending messages or small businesses.
As a sole proprietor, you still need to complete the 10DLC registration process to let carriers know who you are and what messages you’re sending to customers.
To complete 10DLC registration, follow these three steps:
- Brand verification: Provide information about who is sending the messages.
- Campaign approval: Register what is being sent for each of your use cases and how you’ll manage customer consent.
- Submit phone numbers: Associate your 10DLC phone numbers with your Campaign by adding them to the Sender Pool of the Messaging Service associated with your Campaign.
There isn’t an exact timeline because 10DLC registration requires approval from carriers, Twilio, and external vetting partners.
We estimate that it takes under one week to get campaign approval.

Yes, when you register your 10DLC phone number to your brand, you register campaign use cases for your messages that say why you’re sending to customers. Your campaign use cases must first be approved.
And if you need to add new use cases for another purpose, you may need to register another campaign to stay within compliance.
