Before your agency can text anyone, the carriers have to know who you are
AT&T, T-Mobile, and Verizon require any organization that sends automated texts to register who it is and what it sends. Since February 2025 they have blocked traffic from anyone who has not. Your agency can hand that work to eCourtDate, an approved Campaign Service Provider, or build it in-house on Twilio and keep it running for as long as you send.
How carrier registration works
The registry and the carriers hold every sender to the same three steps, whether it is a national retailer or a county probation department.
- 1
Your agency registers as a brand
In the registry’s vocabulary, a brand is a sender. Registering one means verifying your agency’s legal identity and its standing as a government entity. Every message you send afterward traces back to that record.
- 2
You register what you send as a campaign
A campaign describes the messages themselves: court date reminders, payment notices, supervision check-ins, victim notifications. Carriers read the description, review sample messages, and approve the campaign before a single text can leave.
- 3
Carriers assign a sending tier
Each carrier sets how many messages your agency may send in a day and how quickly they move through the queue. The tier depends on what kind of organization registered. A verified government agency is placed at the top.
Two ways to get registered
Sooner or later someone in IT points out that Twilio can send a text for a fraction of a cent. That is true as far as it goes. Sending is the easy part. What takes work is registering the agency, getting its campaigns approved, and keeping all of it in good standing through every rule change the carriers hand down. One of two teams has to do that work: yours, or ours.
Built on Twilio
- When the registry rejects a submission, someone on your staff has to work out why, rewrite it, and pay for another review. The reasons are rarely obvious.
- Consent records, opt-out keywords, quiet hours, and duplicate suppression all have to be written into the integration, then rewritten every time the rules move.
- A carrier can filter a message and still report it as delivered. Unless your team builds monitoring to catch the gap, nobody knows a reminder went missing.
- Links go out through a shared public shortener unless you register and maintain a domain of your own.
- The registration rules changed several times through 2026. Each change lands on whoever owns the code.
- A general-purpose messaging API is not a CJIS environment and does not run in AWS GovCloud. Everything built around it has to make up the difference.
On eCourtDate
- eCourtDate prepares and files the registration. If the registry sends anything back, we handle the resubmission.
- Opt-out keywords are honored on every send, and any scheduled messages to that person are cancelled the moment they reply.
- Carrier blocks are watched for and escalated. Affected messages can be resent through an alternate campaign while the issue is resolved.
- Trackable links run on your agency’s own domain.
- Rule changes are absorbed by the platform. Your agency rebuilds nothing.
- CJIS compliant, hosted in AWS GovCloud, WCAG 2.2 AA.
Registration is one line in a much longer list. The Build or Buy page covers the rest.
The tier that decides whether your reminders go out on time
The registry sorts every sender into a throughput tier, which sets how many messages it can send in a day and how quickly they move. Commercial brands start at the bottom and pay an outside vetting firm to move up. A verified government agency is placed at the top from the start, without paying anyone.
The catch is getting the government status confirmed. Submissions fail on details most agencies have no reason to know, and each rejection sends the application back to the end of the queue. eCourtDate files registrations for justice agencies every week, and government registration is the only kind we do.
Top Carrier Tier
A verified government agency receives the highest message class on AT&T and uncapped daily volume on T-Mobile, for every use case it registers. Commercial senders start at the bottom tier and pay to climb.
Nothing to Buy
Commercial brands pay an outside vetting firm to earn a higher tier. Government status carries that placement on its own. There is no vetting fee and no one to hire.
Filed as a Justice Agency
Every eCourtDate customer is a justice agency, so government registration is the only kind we file. On a generic API it is a footnote in documentation written for retailers and marketers.
Who does what, and how long it takes
Registration happens during onboarding. Your agency never files anything with the registry or the carriers, and nothing comes back to your desk for a second try.
Your agency provides
- A few identity details about your agency.
- Confirmation of what you plan to send.
eCourtDate does
- Prepares and files your brand and campaign through our Campaign Service Provider connection.
- Answers anything the registry or a carrier sends back.
- Assigns your numbers, or ports the ones you already use, and completes the carrier setup around them.
- Watches deliverability once you are live.
- Agency verification
- Usually within an hour
- Campaign approval
- 5 to 15 business days
- While you wait
- Build templates and automations, and run them in a test mode that sends nothing

The Campaign Registry, the body carriers use to register senders, lists eCourtDate publicly as an approved Campaign Service Provider: a platform cleared to register and send on behalf of many organizations at once. eCourtDate is CJIS compliant and runs in AWS GovCloud. Your IT team can check every one of those claims against our security documentation.
