Toll-Free Verified Sender Form Step-by-Step Guide

Before you start:

• Have the toll-free number ready. It must already be on your Sinch account. If not, buy or host a toll-free number first.
• If you're porting voice and messaging, fill out this this Letter of Authorization (LOA) and Log into the Sinch Support Portal → Submit a request, and select the following:
  • Region: US/Canada
  • Product information: Numbers & Connectivity
  • Numbers: Toll-Free – Voice + Messaging
  • Case Type: Number Porting Issue/Request – VOICE AND MESSAGING
  • NOTE: Be sure to tell us your Account ID, Project ID and SMS Service API you intend to use when the number ports.

• Prepare the opt-in evidence: a public URL to an image showing how customers opt in, plus a written description of the process.
• Have the business's privacy policy and terms and conditions URLs ready.
