SMS setup guide

Enable two-way texting through Second Door

Before you start

US carriers require every business that texts patients from a local 10-digit number to register its brand and messaging campaign first. This one-time process, known as A2P 10DLC registration, verifies who you are and what you send. Second Door submits the information to The Campaign Registry on your organization's behalf.

Approval typically takes a few days to a few weeks. Texting stays off until it's approved, and turns on automatically once it is.

Your phone service is never interrupted. Your numbers stay yours, with your phone company. Calls, voicemail, and call routing stay exactly as they are today. Only texting is affected.

What you'll need

Collect these before you open the form:

  • Your legal business name, business type, and EIN
  • Your practice's website URL
  • Your organization's physical business address
  • The name, email, phone, and role of the person authorized to manage SMS messaging for your organization

If you don't see SMS in your settings, reach out to support@seconddoorhealth.com.

Complete your campaign registration

  1. In Second Door, go to Settings > Integrations > SMS

  2. In the Campaign Registration section, fill in the three groups of fields: Business Information, Business Address, and Authorized Representative. Read the following tips before you submit:

    1. Legal Business Name. If your practice operates under a name different from its legal entity, enter both, formatted as your legal entity name, then "dba," then the name patients know you by. Reviewers check your registered name against your website, and a name they can't connect to the practice on that site slows approval down.

    2. EIN. Enter it exactly as it appears on your IRS documentation, including the hyphen (XX-XXXXXXX).

    3. Website URL. Use your practice's live site. Reviewers visit it as part of approval.

    4. Job Position. Enter the representative's role in the organization. Add their exact title in Job Title if it differs; that field is optional.

    5. Use your organization's physical business address. A mistyped EIN or address is the most common reason a registration doesn't get approved, so check both before you submit.

  3. When everything is filled in, click Submit Brand Registration.

  4. Return to this page to check on the status. You'll also receive an email notification with status updates from Second Door.

That's everything you need to do. Second Door completes the rest of the registration for you, including the campaign details and the consent, privacy, and terms information carriers require.
