Error code

30701: Brand Registration Failure: Invalid input parameters

What this error means

One or more fields you submitted failed format validation before the registration even reached the registry.

Causes, most likely first

  1. A text field over its length limit (business_name, friendly_name, street, email, website_url, stock_ticker, names).
  2. phone_number / mobile_phone_number not in E.164.
  3. Address fields don't form a valid address for the country (US/CA region must be the 2-letter state/province code).
  4. Malformed email, unknown domain, or disposable domain.
  5. Unsupported enum value for stock_exchange / business_industry.

How to fix it

If your numbers are managed by a platform

If your numbers sit inside a reseller platform, for example LeadConnector numbers inside GoHighLevel, you do not have access to the Twilio Console, and the interface shows the rejection without the code. Ask that platform's support team for the Twilio rejection error code, in writing, before you change anything. You can also read it yourself from your browser, which is faster: see how to get the code.

The substance of the fix is yours to make: the business details, the website, and the opt-in flow described in the Twilio path all belong to you, not to the platform. Make those changes first, confirm they are live, then ask support to resubmit. A resubmission filed before the underlying facts change will fail again on the same reason.

If you own the Twilio account

Read the returned field names in the error detail, it names the exact properties. Fix only those, then resubmit. If the bad data lives in the Customer Profile / trust bundle rather than the brand, correct the bundle first, then resubmit the BrandRegistration.

Timing and resubmission

Purely synchronous validation, no review window. Resubmit as soon as the fields are corrected. Note that each brand submission attempt may carry a TCR fee.

Two ways forward
