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.

📢 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

In accordance with the latest regulations issued by the Taiwan NCC that "all message content must include the brand name", please be kindly informed that brand name registration will be mandatory toward Taiwan starting from November 1, 2025. Below is a detailed clarification of the changes:
Implementation Timeline: Non-compliant messages (those without a brand name) will be blocked starting November 1, 2025.
1. Brand Name Inclusion in Message Content As previously communicated, all SMS messages directed to Taiwan must include the brand name. Please note that Sender ID is not supported for Taiwan destinations—all messages will be delivered via a Shared Long Code (Shared LC). This requirement pertains specifically to message content.
Brand Name Format and Placement Guidelines: · We strongly recommend placing the brand name at the beginning of the message to minimize filtering risks. · There is no character limit for the brand name. · Abbreviations are permitted only for widely recognized brands. · The use of brackets (e.g., [ ]) is allowed but not mandatory.
Recommended Message Templates: · [Brand] Your OTP is xxxx · Brand Your OTP is xxxx
2. Brand Name Registration To ensure continued message delivery, brand name registration is mandatory. This process requires submitting company details and Know Your Customer (KYC) documentation for the brand owner. Again, please note that Sender ID remains unsupported for Taiwan.
#Registration Information and Required KYC Documents There are no specific requirements for aggregator or reseller traffic. All documentation must be associated with the brand owner.
Required Brand-Owner Company Details include: · Brand name · Company name · Company website · Company registration number · Main company contact number · Sample message templates
Required KYC Documents include, but are not limited to: · Business certificate (A) · ID of company representative (B) · Taiwan KYC registration form (C)
Note: · Additional documents may be requested. However, (A), (B), and (C) are mandatory. · In compliance with data protection guidelines, submitted documents will not be retained. Clients must resubmit all documentation for each new brand name registration.
##Attention## · Restrictions for Certain Financial Sectors · Telecom operators in Taiwan may no longer support messaging services related to loans, lending, and cryptocurrency. To confirm whether a specific traffic type is permitted, we recommend submitting a brand name registration request to receive official confirmation from the operators.
Your prompt attention to these requirements is greatly appreciated. Should you have any questions or require further clarification, please do not hesitate to contact us. 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:
• 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; • between 30 November 2025 and 30 June 2026, businesses and organizations will need to register sender IDs via their participating telco or EMSPs; • 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 ‘Unverified’.
We recommend brand owners to review your current sender IDs under the official regulation as follows:
• Alphanumeric supported: 2-11 characters; • Only-number not supported; • Not containing the word 'Unverified'; • Not starting or ending with a space or underscore; • Not including prohibited words: https://www.acma.gov.au/restricted-terms-sender-ids; • 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
