SMS registration requirements

Suggest Edits

Since 1 June 2023, new UK SMS bulk sender filters require us to register any new Sender ID, also known as Originator, with the mobile network operators (MNOs). This process can take 2-3 weeks, in addition to the time taken to set up the virtual mobile number (VMN) required to handle opt-outs as part of basic SMS Configuration.

If requested by Support, the following information needs to be provided in order to set up a custom originator:

  • Originator to be registered (must be between 3 and 11 characters, no spaces)
  • The legal company name operating the originator.
  • The country of the operator.
  • URL for the operator's corporate website.
  • Operator's industry vertical.
  • Call-to-action URLs used in messages.
    • A primary CTA, and any number of additional.
    • Cannot include URL shortening services.
  • Description of use case.
  • A real example of what an SMS will look like.
  • Estimated monthly volume.

In addition, if the originator is a major financial or government brand, a signed & headed Letter of Authority will be in order to authorise delivery using the company name.
