What to expect when a registration error occurs

How to know when an error has been identified

If your Brand or Campaign registration is rejected, you'll be notified by email and see an alert in your control panel under Settings > Phone numbers > Compliance and registration.

How errors are handled

When you submit your registration, NationBuilder passes that information through to our phone number and texting provider, Twilio. The embedded Twillio form validates this data before submitting it to The Campaign Registry, which pairs with US mobile carriers to verify senders. If Twillio identifies any errors after the form submission, you will get an automated email prompting you to update your registration.

How to correct an error

Go to Settings > Phone numbers > Compliance and registration and select Update registration. You'll see exactly which field or fields need fixing, you don't need to re-answer the whole form, just the flagged information.

If you're not able to resubmit yourself, or the error message asks you to contact us directly, reply to the notification email or reach out to [email protected] and our support team will help you resolve it.

Common Registration Errors

When a registration cannot be submitted successfully, the most common reasons for rejection are:

  1. The official name or address provided for the organization do not match the information provided on tax forms

  2. The texting use case provided doesn't match the business type and company type provided

  3. The sample messages, opt-in language, or linked privacy policy and terms don't meet carrier requirements
