International Sending Policy

  1. Introduction

As part of an ongoing approach to protect consumers from fraudulent and malicious SMS, regulators around the world are introducing certain requirements on messages. In some regions, this includes a requirement to register Sender IDs. The purpose of this International Sending Policy is to enable you to have a better understanding of those requirements when using our service and any facility we provide.

  1. Regional requirements

Region Requirement

From 30 January 2023, the Infocomm Media Development Authority (IMDA) is implementing the  Full SMS Sender ID Registry Regime (SSIR) which requires organisations sending messages to register all Sender IDs with the SSIR, including alphanumeric sender IDs long codes and short codes.

You must complete registration with the SSIR, including any pre-registration requirements as applicable, such as obtaining a unique entity number from the Accounting and Corporate Regulatory Authority.

Once you have registered your Sender ID(s), contact customer support to obtain a Letter Of Authorisation which you will need to complete on your company’s letterhead and return to us.

The IMDA will allow Participating Aggregators to create a common Sender ID “ Likely-SCAM” to allow SMS with unregistered Sender IDs to be channelled into this thread from 30 January 2023. The IMDA expects this transitional period will be open for approximately 6 months, thereafter any messages with unregistered Sender IDs will be blocked.

United Kingdom  

From 12 September 2023, carriers will block the following sender IDs used to send messages to the UK.

  • International numeric sender IDs (non-UK numeric sender IDs).
  • Short codes that don’t follow UK short code format (five digits starting with 6-8).
  • Alpha Tags/Alphanumeric IDs containing generic senders (e.g., “Alert”, “Verify”, “Info” and similar variations) AND senders containing any of these generic terms.
    • Variants of these ID’s (e.g., “_Verify_”, “VER1FY”, “VER IFY” etc.) will also be blocked in the future.
  • Alpha Tags/Alphanumeric ID’s containing non supported characters.

Alpha Tags may only contain the characters: a-z, A-Z, 0-9, and – or _

Customers sending SMS messages after September 12, 2023 from sender IDs that don’t conform to the above requirements may incur liquidated damage charges of up to £5,000.
