  • United Kingdom enforces strict segmentation between marketing and transactional messaging:
  • Each Sender ID can only be registered for one segment—either marketing or transactional. If your content spans both, you must register separate Sender IDs for each.
  • Generic senders (e.g. Verify), sub-variations of generic senders (verify), and senders which contain part of generic senders (VerifyCode), are not allowed.
  • Following special characters are allowed: "." (dot), "-" (dash), "_" (underscore), " " (space), "&" (ampersand). All other special characters are not supported.
  • Character replacement (e.g. A to 4, or B to 8, etc.) is not allowed.
  • If the company name and requested sender have different names, please make sure to specify what is the connection between them.
  • Sender IDs belonging to Russian companies can not be registered

What this market refuses

Gambling is legal and regulated in this market. All forms of online gambling require a license from the Commission. To register a Sender ID, you must include a copy of your gambling license with your request. Additionally, some senders are protected by UK operators, which may require an authorization letter for registration.

How sending works

Use the same SMS API across supported destinations. Prepare an eligible sender, enable the destination and apply the recipient permission your message requires. Track the accepted message through carrier submission and the delivery reports available for that route.

Sending to United Kingdom, answered

What senders ask before their first message to United Kingdom.

Do I need to register a sender before sending SMS to United Kingdom?
The reference requires registration for every listed sender type: a short code, an alphanumeric sender ID, and a long code. Work with Bird on short-code assignment, registration and costs. Short codes are country-specific. For an alphanumeric sender ID the name itself is registered. Confirm how the approved sender is presented on the destination networks. A phone number is registered for this country before it can send business messages. Each sender ID is registered for either marketing or transactional messages, not both. If you send both kinds you need one sender ID for each.
Can I use an alphanumeric sender ID in United Kingdom?
Yes, once the sender ID has been registered. Confirm how carriers present it to recipients. Generic sender names, or names that contain one, are refused. The only special characters allowed are full stop, hyphen, underscore, ampersand, and space. A letter cannot be replaced with a look-alike digit.
How long does sender registration take in United Kingdom?
The recorded estimate for a short code is about 40 business days; confirm timing before launch. The recorded estimate for an alphanumeric sender ID is about 5 business days; confirm timing before launch. The recorded estimate for a long code is about 5 business days; confirm timing before launch.
Can I receive replies from United Kingdom?
Yes, if you send from a short code or a long code. Replies are delivered to you as signed webhooks.
Are there quiet hours for SMS in United Kingdom?
Quiet hours are recorded here. Confirm the applicable sending window for your message purpose and recipient location.
Do I need consent before messaging someone in United Kingdom?
Yes. The recipient must opt in before you send the first message. Provide an appropriate opt-out route and honor the recipient’s preferences.
