A2P 10DLC explained: why your GoHighLevel texts are not delivering
If your automations show “sent” but customers say they got nothing, this is almost always why. The fix is paperwork, not technology.
Since 2023, US carriers require every business sending texts from a normal 10-digit number to register the brand and the campaign. Unregistered traffic is filtered, sometimes silently. GoHighLevel will still mark the message as sent.
What registration involves
- Brand registration. Your legal business name, EIN, address and website. It must match your IRS records exactly or it is rejected.
- Campaign registration. What you send (appointment reminders, follow-ups), sample messages, and how people opt in and out.
- A compliant website. A privacy policy that mentions SMS, and a form with a visible consent checkbox. Reviewers check this.
The mistakes that get accounts rejected
- Business name on the form does not match the EIN record.
- Sample messages without the business name or opt-out language.
- No opt-in checkbox on the website form, or no privacy policy at all.
- Using a personal Gmail as the business email.
Warming up a new number
Even registered, a brand-new number sending 500 texts on day one looks like spam. Start with reminders and replies to real conversations, then add campaigns over two to three weeks. Keep reply rates healthy by asking questions rather than broadcasting.
Outside the US
The UK and Canada have their own rules: alphanumeric sender IDs, express consent, clear opt-out in every message. The Gulf is WhatsApp-first, so most of my UAE and Saudi clients run follow-up through the WhatsApp Business integration instead of SMS.
