Identified - Telesign is currently unable to ensure that messages sent to mainland China are reliably delivered because of restrictions around content, encoding, signatures, and use case. These restrictions have resulted in the blocking of seemingly legitimate and registered customer traffic. Due to this, Telesign is currently able to support China Signature/Short Code registration only for local companies and messages sent through Telesign would be delivered on a best-effort basis with limited support only.
The signature/short code registration process for local companies or those with a local presence typically takes 3-4 weeks.

π’ Dear valued clients, we bring you a crucial update! To streamline operations in the UK, SID approval/whitelist is now a prerequisite. Going forward, it is imperative for the end client or brand to provide the following details:
1. Sender ID (case sensitive) 2. Message Content Sample (including any URLs if present in the content) 3. Expected Monthly Volume
Generic SIDs are no longer allowed.
Your cooperation in meeting these requirements is highly appreciated. Posted on

The Australian Communications and Media Authority (ACMA) has officially applied a new timeline for the new Australian SMS sender ID register. As before, every business or agency seeking to use a sender ID will have to comply with the registration guidelines. Please be aware of the following timeline:
β’ from 15 October 2025, Telcos and electronic message service providers (EMSPs) will need to apply to the ACMA if they want to participate in the SMS Sender ID Register and continue to carry messages with sender IDs; β’ between 30 November 2025 and 30 June 2026, businesses and organizations will need to register sender IDs via their participating telco or EMSPs; β’ from 1 July 2026, onward only participating telcos will be able to send SMS and MMS with sender IDs, and unregistered sender IDs will be replaced with the word βUnverifiedβ.
We recommend brand owners to review your current sender IDs under the official regulation as follows:
β’ Alphanumeric supported: 2-11 characters; β’ Only-number not supported; β’ Not containing the word 'Unverified'; β’ Not starting or ending with a space or underscore; β’ Not including prohibited words: https://www.acma.gov.au/restricted-terms-sender-ids; β’ Not containing a word or words that are offensive, deceptive or misleading.
For complete registration details, Telesign will ensure that new updates are communicated promptly, and that we remain fully compliant with the new regulation. In the meantime, no impact is expected for existing sender ID usage in Australia, before 1 July 2026. Posted on
