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.

Regulatory Update - UK SID Whitelisting Introduced Jan 6, 2025 03:29 - Jun 7, 2025 06:29 PDT

📢 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.

Regulatory Update: 📢 Important Announcement: China Registration Process Change Apr 16, 2025 13:30 - Sep 13, 2025 13:30 PDT

Scheduled - 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.)

This fee will apply to both newly registered Sender IDs and those already approved.

Regulatory Update:📢 China Mobile - Blocking Phone numbers and Website/URLs in Message contents hosted outside of China Jun 1, 2025 01:20 - Oct 29, 2025 01:20 PDT

Scheduled - 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.

📢 Important Update: Telekom Romania (Cosmote) - New Sender ID Registration Forms Jul 8, 2025 01:18 - Nov 10, 2025 00:18 PST

To comply with Telekom Romania (Cosmote) regulatory requirements effective immediately, all clients registering Sender IDs must submit one of the following Letter of Authorization (LOA) forms:

#Required Forms (kindly choose one):
• Trademark Use Agreement — if the Sender ID matches your registered brand/trademark
• Sender ID Use Agreement — if the Sender ID does not match your brand/trademark
Clients are responsible for selecting the correct form based on their Sender ID usage.


#Key Points to Note:
1. These new LOA forms are mandatory for all new Sender ID registrations toward Telekom Romania (Cosmote).
2. Chain of LOAs is accepted.
3. No other changes to the registration process, all previously required details remain the same and are included within the new LOA templates.

Thank you for your cooperation.
