10DLC
Also known as: A2P 10DLC, 10-digit long code
10DLC is a U.S. system for sending application-to-person (A2P) business texts over standard 10-digit local numbers, requiring brand and campaign registration with the carriers.
10DLC is the framework that lets businesses send legitimate text messages from ordinary 10-digit local numbers, instead of short codes, while staying within carrier rules. It requires registering your brand and the purpose of your messaging, which carriers use to grant throughput and filter out spam.
For call tracking platforms that also offer business texting, 10DLC registration is what keeps local-number messaging deliverable and compliant, alongside consent obligations under the TCPA. See two-way texting for business.
Frequently asked questions
Do you need 10DLC registration to text from a tracking number?
To send business (A2P) texts from a local 10-digit number to U.S. recipients, yes, carriers require the brand and messaging campaign to be registered. Registration improves deliverability and reduces the chance of messages being filtered or blocked.
What does 10DLC mean?
10DLC stands for 10-digit long code: a standard local phone number approved for application-to-person (A2P) business texting in the U.S. once the brand and its messaging campaigns are registered with the carriers.
What is the 10DLC law?
10DLC is not a single law; it is a registration framework the U.S. mobile carriers require for business texting over local numbers. It works alongside consumer-protection laws like the TCPA that govern consent and opt-outs, but the registration itself is enforced by the carriers, not a statute.
How long does 10DLC registration take?
Brand registration is often approved within hours, and campaign vetting usually clears in a day or two. Use cases that need extra review can take longer, so plan for a few business days before you rely on texting from a new number.
