Alphanumeric sender IDs, no registration · billed in GBP · global data region
United Kingdom allows an alphanumeric sender, and asks for no registration to use one. Set `from` to your brand and the message arrives under it. Nothing to file, nothing to wait for, which is the exception rather than the rule in this part of the world.
Ask for SMS and email in one verification and the code falls through to email when the SMS is not delivered in time. The person sees one code and one input box. On routes where filtering is common this is the difference between a sign-up completed and a sign-up abandoned, and you wrote none of it.
Every message to United Kingdom records the carrier it went out on, the score that carrier held at the time, the reason it was chosen and what it cost. It is on the message in the API response and in your logs. Carriers are scored on whether codes are actually entered, not on whether a receipt said OK.
An account on the United Kingdom endpoint is billed in US dollars today. Billing in GBP is where this is going, and it is a real advantage when it arrives, but a converted price needs a published rate behind it and there is not one yet, so we quote one currency rather than invent a second. Funds are reserved at the published price when a message is accepted and settled when it is delivered; a message we never deliver is never charged for, and a hard spend cap you set is enforced rather than invoiced.
United Kingdom allows alphanumeric sender IDs, so a message can arrive from your brand name rather than a number, with no registration needed.

E.164: a plus, the country code +44, then the subscriber number, as in +44712345678. Woyra strips spaces, hyphens, brackets and a leading 00, but it will not guess a missing country code, because the same digits belong to a different subscriber in every country.
uk.woyra.io, though the same API key works on every endpoint Woyra runs. Which one you call decides the compliance rules applied, the currency you are billed in, and — where residency requires it — which data plane answers.
