## What this country needs

### SMS

- **Your sender** — Your alphanumeric sender is accepted as it is.
- No registration needed — creating the sender is enough.

### RCS

- **What they ask for** — Brand verification by a third party · Email to the operator · A public inbox somebody watches
- **Who acts** — You send the email to the operator yourself.
- **Have this ready** — A public profile phone number using the +44 prefix; A named brand contact with a corporate email address they read daily; The ability to allowlist the senders we tell you about in your mail filter; The logo and banner we provide, to attach to the authorisation email
- **Without an approved registration** — Nothing is sent to this country until the registration is approved.

The brand is verified **along several tracks at once**, and part of that verification arrives **by email to your named contact**, on short deadlines that run on their own.

Name someone who reads their mail daily and checks the spam folder. Once the request is under way we tell you which senders to allowlist and what each step expects.
