Upcoming Sender Restrictions as of 31st October 2023

In an attempt to fight the ever-increasing smishing & phishing in UK, a new series of measures & restrictions will be put into place.

The below measure that will be put in place impacts international numeric, short code senders, generic alpha tags & special characters, please see below.

  • International numbers will be blocked
  • Alpha Tags going forward will be expected to be brand centric
  • Alpha tags containing special characters will also be blocked. Please, see below the only characters that will be supported in the alpha tag from July on; any other character not listed below will be considered a ‘special character’ and therefore subject to blocking on the operator side.

Any messages sent containing any of these generic terms will be blocked. Alpha Tags are expected to be brand specific.

United Kingdom Sender ID options

This is a fully featured route and delivery to ported numbers is supported.

When Sending an SMS through our platform, we give you a few options:

  • A shared number (default) - we assign a number to the outgoing SMS so the user can reply. You can setup rules for incoming SMS, anything is possible.
  • Your own number - replies will be sent to you as an SMS. Replies will be sent to your mobile number and will not show on the account dashboard.
  • Your alpha tag - e.g. "MyCompany". The receiver can't reply. This can be 11 characters maximum with no spaces. This alpha tag should be brand specific.
  • Your dedicated number* - you can purchase a ClickSend dedicated number. You can setup rules for incoming SMS, anything is possible. *If you require call forwarding please contact chat or support@clicksend.com

Messages will be blocked by the network if the number is a Lyca mobile originating number.

The range 74402 is blocked as Lyca mobile prefixes(senders) are not allowed due to grey route blocking protection on our platform. The recommended action would be to not use any senders that start with 74402 against 3-UK numbers.
