How it works

From sign-up to first send.

Texting at scale in the US goes through review by carriers and The Campaign Registry. Our automatic A2P process handles the paperwork and aims to get you approved within 48 business hours. Carriers and the registry make the final call, so it isn't a guarantee.

Step1

Register your brand

Automatic · steps 1 and 2 together, aiming for 48 business hours

Every business texting through 10DLC needs a registered brand. We draft yours from a few plain answers about your business and file it directly as a CSP, under your identity.

You'll provide your legal entity name, EIN and contact details. Most brands verify quickly. A small share get flagged for manual review by the registry, which can take longer. We tell you which path you're on.

Step2

Vet your campaign

Runs alongside step 1

A campaign describes how you'll message people: the use case, sample messages and your opt-in language. We check it against carrier rules before submitting, so problems get fixed before a rejection.

Missing opt-in proof, no STOP/HELP language and prohibited content are the usual causes of rejection. We flag all three up front.

Step3

Get a number or port yours

New: minutes · Porting: 1–3 weeks

Buy a local or toll-free number in one API call, or port in the numbers your customers already know. The same number handles texts and calls.

Porting timelines depend partly on the carrier you're leaving. You'll always see the current status, what's blocking it and a target date.

Step4

Go live

As soon as you're approved

Send from the console or the API. Delivery status streams to your webhook in real time, and spend reconciles to the cent from the first message.

You start with standard throughput. Limits rise as your sending reputation builds, and you can always see your current headroom.
