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.

China Unicom has announced to apply new regulations governing URL and phone number inclusion in message content. This new regulation applies to both China Mobile and China Telecom that has announced updates recently.
- URL and phone number hosted outside of China in message content are blocked - One signature can only register 1 URL and 2 phone numbers in its message content.
To support compliance with the latest requirements set by Chinese telecom authorities, the following registration requirements are now enforced:
## Signature Registration Requirements: a. Signature to be sent (the signature must match registered company name, app name or trademark) b. Chinese entity name (official registered business name) c. Unified credit code of the company (company registration identifier) d. Scanned copy of Business license(China based entity) e. Scanned copy (both sides) of contact Chinese ID card f. Contact Mobile Number (+86 prefix) g. Message template (proposed content sample) h. Letter of Authorization (LOA) (ONLY if trademark owner differs from submitting entity) *i. Phone numbers and URLs hosted outside China in message contents will be blocked. To send messages with phone number(s) and URL, submitting message contents with URL and phone numbers for operator's reviewing and whitelisting is mandatory.
## Message content submission Guidelines (i*): a. Each registered signature may include only one URL and maximum two landline numbers. b. URLs must be supported by a valid Chinese ICP registration; unregistered domains will fail operator's review.
These consolidated regulations reflect current practice across all domestic networks in China. We encourage you to align with these rules to ensure smoother processing and higher delivery success rates.
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) is in consultation to establish and maintain the Australian SMS sender ID register, to better protect consumers from SMS-related scams. This is done under the Telecommunications (SMS Sender ID Register) Industry Standard 2025. The upcoming changes will directly affect how telcos and messaging service providers operate. It will also require every business or agency seeking to use a sender ID to register it and prove they have a valid reason for its use.
Provided timelines: - 2025, Sep 30: ACMA creates industry standard - 2025, Oct 15: Onboarding of Telcos - 2025, Nov 30: Registration of entities with Telcos - 2025, Dec 15: Commencement of SMS Sender ID Register
Until the standard is officially announced, Telesign will continue collaborating with our partners and ACMA to clarify and define a clear procedure for sender ID registration. We will ensure that any updates are communicated promptly. Posted on

We have been notified by the Taiwan National Communications Commission (NCC) about the below regulation which has already been applied for communications directed to Taiwan:
- All message content must include the brand name
While operators are still finalizing enforcement protocols (including penalties and traffic-blocking mechanisms for non-compliance traffic), no enforcement measures are currently active. However, enforcement may commence imminently without further notice.
To align with this regulation, we strongly recommend you immediately begin incorporating brand names into message content.
We will continue monitoring and provide updates upon receipt of additional guidelines. Posted on

In alignment with previous efforts by Thailand's National Broadcasting and Telecommunications Commission (NBTC) to combat digital frauds, all SMS messages containing URLs must now have those URLs whitelisted. This regulation has been in effect since 1st Feb 2025, and applies to all SMS traffic types. It is also compulsory to register for a sender ID in Thailand.
#URL whitelisting requirements for SMS delivery to Thailand: 1. Sender ID 2. Company Name 3. Company URL/Website 4. Message Content with URL 5. Full URL 6. Company Registration Number
#Guidelines from the AMLO's (Anti-Money Laundering Office): 1. URLs must direct users to legitimate and verified destinations. 2. URLs must not lead to interactive platforms such as direct download sites or forms requiring user input. 3. The purpose of the URL must be transparent, lawful, and clearly communicated in the intent registration process. 4. URLs used in SMS campaigns may require prior approval from the National Cyber Security Agency (NCSA) - the process and approval time are to be confirmed in the official decree. 5. URLs that are generated by URL shorteners, such as Bitly, are not allowed as it is considered leading to a platform not belonging to the owner of the Sender Name.
Telesign has proactively submitted available URLs for registration with Thai operators to ensure optimal delivery rates and compliance. We will continue to monitor the evolving regulatory environment and provide updates as they become available. For URL registration support, please reach out to your account manager or our Support team. 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

We have recently received new regulations pertaining to China Mobile, specifically concerning the inclusion of phone numbers and website URLs in message content.
#Regulation Scope - Effective Date: June 1, 2025 - Applicable Traffic: All traffic destined for China (from our perspective, this includes both international and local traffic). - Note: From the perspective of Chinese operators, "Generic" traffic without any signature registered is still considered "local" traffic to China. Generic traffic serves as a workaround for international traffic and operates on a best-effort basis.
#Regulation Details 1. Content Restrictions - China Mobile will block any messages containing phone numbers or URLs hosted outside of China. - Phone numbers with country codes outside of China will be classified as "hosted outside China." - URLs with IP addresses hosted outside of China will be classified as "hosted outside China."
2. Approval Process for Compliant Content - Messages containing phone numbers and URLs hosted within China may be delivered, provided that customers: - Submit the content for review. - Obtain whitelisting approval prior to sending any traffic.
3. Submission Requirements - URL Format: Only the second-level domain needs to be declared; a complete link is not required. Examples: domainA.com; domainB.com - China Telecom Requirements: Each whitelist request per signature may include a maximum of 1 URL and 2 phone numbers.
Currently, there are no delivery issues associated with this regulation. However, to ensure full compliance with the new requirements, please adhere to the following guidelines: 1. All URLs and/or phone numbers included in your messages must be registered alongside your local signatures. Messages containing unregistered URLs or phone numbers will be blocked from delivery. 2. For traffic using a generic signature, we recommend omitting URLs and phone numbers from your content to avoid potential delivery disruptions.
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.
