A2P 10DLC Registration

Why do I need to register for 10DLC?

  • The phone carriers require it before you can send text messages. Until your registration is approved, your outbound SMS will not go out. 📄 A2P 10DLC Registration guide

What do I need before I can register?

  • A live, compliant website, your business officially registered if you are registering as a business, and a valid EIN issued by the IRS if applicable. 📄 A2P 10DLC Registration guide

Can I register a DBA instead of my LLC name?

  • Yes. Contact support so they can submit your DBA for 10DLC registration. (Day 4 Webinar, Sept 11)

Do I need a website to register?

  • Yes, and it must be live before your registration can be submitted. You can update your existing site, or build one with the REsimpli Website Builder at https://resimpliwebsites.com/ 📄 A2P 10DLC Registration guide

What DNS records do I use for a REsimpli website?

  • Two A records pointing to 54.188.250.92 — one with host @ and one with host www. Wait for DNS propagation and confirm your site is live before continuing. 📄 A2P 10DLC Registration guide

What does my website need to include?

  • SMS opt-in language, a consent checkbox, a description of the messages users will receive, your registered company name in the opt-in language, standalone Privacy Policy and Terms & Conditions pages, and clickable links to both inside the opt-in language. 📄 A2P 10DLC Registration guide

Can I make the consent checkbox mandatory?

  • No. Users must be able to submit the form without ticking it. A required checkbox will fail compliance. 📄 A2P 10DLC Registration guide

Does every form on my site need opt-in language?

  • Every form that collects a phone number does, not just your main contact form. 📄 A2P 10DLC Registration guide

What information does the registration form ask for?

  • Business details including your legal company name, DBA, EIN and issuing country, contact details; your website, Privacy Policy and Terms & Conditions URLs; your business address; and campaign information including a description and two sample messages. 📄 A2P 10DLC Registration guide

What does registration cost?

  • $50 to enable messaging to T-Mobile numbers, a $4 carrier registration fee, and $10 per month for every 1–49 phone numbers. The guide lists a $64 one-time registration total. 📄 A2P 10DLC Registration guide

How long does carrier review take?

  • Around 2 to 4 weeks, though processing times vary. This is outside REsimpli's control. 📄 A2P 10DLC Registration guide

What happens when my registration is approved?

  • Your Brand and Campaign become active, your existing phone numbers are linked to the campaign automatically, and newly ported numbers are linked once configured. 📄 A2P 10DLC Registration guide

Will my SHAKEN/STIR registration carry over to 6.0?

  • Yes, including numbers submitted for registration recently. You do not need to resubmit. (Day 4 Webinar, Sept 11)

Why was my registration rejected?

  • The common causes are business information that does not match your documentation, EIN verification problems, website compliance issues, a missing Privacy Policy or Terms & Conditions, or missing or incorrect SMS opt-in language. Fix the issue and resubmit. 📄 A2P 10DLC Registration guide

I'm approved but still can't send texts.

  • Your numbers may not be linked yet. Existing numbers usually link within a few days of approval. 📄 A2P 10DLC Registration guide
