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

There are new requirements for signature registration for China. As previously shared, only local companies can register signature in China. But in order to be compliant, now the signature must match one of the following:
1. Company name (Must be exactly the same as the name on the business license. If the full name exceeds 12 characters, it is recommended to use the company abbreviation). The abbreviation must be included in the full name on the business license and must not be confused with or duplicate other companies. For example, "Beijing XAX Technology Co., Ltd." can be abbreviated as "XAX Technology", but not as "Beijing XAX Technology" or "XX Technology".
2. App name (Must be registered in the MIIT ICP/IP Address/Domain Name Information Filing Management System. Apps under development are not yet eligible for signature application; it is recommended to use the company abbreviation for submission.)
3. Trademark (The trademark must be registered on the China Trademark Network.)

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.

Due to recent changes in Chinese Telecom regulations, signature registrations will now only be supported for companies based in China or have a local presence in China. As a result, all non-local registered dedicated signatures will be replaced by the generic signature 【优速通】 or 【速验通】 effective immediately for China Mobile users, which represents approximately 58% of the market. We anticipate that this change may soon extend to all operating networks with little or no prior notice. While your service will continue to function as usual, the only change will be the use of the signature 【优速通】 or 【速验通】in place of your previously registered signature. For further details, please refer to the official Telecom documentation here: https://www.miit.gov.cn/zwgk/zcwj/flfg/art/2020/art_77bc7219833c4a08b4563ba42ad23e1f.html
We do not expect any negative impact on the delivery of previously registered dedicated codes, and no changes to these codes are anticipated. However, if you are using our Telesign "shared" routes (non-registered traffic), please note the following potential impacts:
- Content containing URLs may experience delivery issues. To mitigate this, Telesign is finalizing a standard signature and code for use via our shared routes: - Signature: 【通乐信】 - Code: 7654321
If your company is based in China and you wish to retain your previously registered signature, please contact our support team at Support@telesign.com with the following information:
- Previously registered signature - Chinese company name - Business Certificate - Unified credit code of the company - Contact Name - Contact ID number
