A2P registration in two clicks
A plain-English guide to A2P 10DLC: what you can complete in minutes, what carriers still review, and how to sequence launch while you wait.

A2P 10DLC registration is often presented as a long, intimidating compliance workflow. In reality, the user-side submission can be straightforward when the product is designed well. The hard part is understanding where your input ends and carrier review begins.
Who this is for
- Operators setting up outbound SMS for the first time.
- Teams deciding whether to register as sole proprietor or legal entity.
- Managers planning launch timelines around carrier review windows.
What A2P actually gates
A2P 10DLC is about texting on US carriers. Nothing else is gated.
- Calling: no A2P required.
- Email: no A2P required.
- SMS on US carriers: A2P required.
Most of the outreach workflow does not need to wait on approval.
Two clicks on your side
With a valid LLC, the user-facing flow is a short set of inputs and a submit. Sole-proprietor users answer a few questions, confirm a mobile number, and submit. In both cases the submission itself takes seconds.
Submission is fast. Approval is not.
Clicking submit in 30 seconds does not mean you are approved in 30 seconds. Carrier review through TCR takes 10 to 15 business days for both legal-entity and sole-proprietor submissions. That window is set by the carriers. Plan around it by launching calling and email first, with SMS queued to flip on the day approval lands.
Sole-proprietor caps
- Throughput: roughly 1,000 SMS per day to T-Mobile, one message per second, one phone, one campaign.
- An OTP code arrives within minutes of submission and expires in 24 hours. Miss it and the registration fails.
- A single mobile number can only be used for up to three sole-proprietor A2P registrations across the entire carrier ecosystem, including other providers.
If you need more headroom, register as a legal entity. The submission is still short and the approval window is the same.
Fast registration is a product problem. Fast approval is a carrier problem. Good software is honest about which is which.
Bottom line
Covent makes the part you control take seconds, and is upfront about the part the carriers control.
