Why do I get this error: ‘Invalid messaging source number’. The ‘from’ number is returned to us when we send texts from a Toll-Free number?

Ultimately you will need to register your toll-free number use case using this form.

The process typically takes 5 - 7 business days.

More information can be found at our Toll-Free Messaging article.
