[2026.4.23] Important Notice on Real-Name Filing for SMS Signatures — App Names No Longer Accepted
Dear Jiguang developers,
According to the Administrative Provisions on Telecom Short Message Services (Revised) released by China's Ministry of Industry and Information Technology (MIIT), an SMS signature must be the full name, abbreviation, or registered trademark of the sender company. Starting May 1, 2026, ICP-filed app names will no longer be accepted as SMS signatures.
Note: If you are currently using "ICP-filed app name" as your SMS signature, that signature may be removed by carriers and become unusable. Please re-create and file a compliant signature as soon as possible to avoid disruption to your SMS service.
1. Filing rules — signatures must satisfy authenticity, specificity, and uniqueness
(1) Enterprise/institution name (recommended): the signature must be the full name or an abbreviation of the company name.
Full name: the complete registered company name.
Abbreviation: every character of the abbreviation must appear in the full name in order (no skipping), and must not collide with abbreviations of other entities.
(2) Registered trademark: the signature must be a trademark officially owned by the enterprise.
The trademark must be findable on the China National Intellectual Property Administration's trademark portal at https://sbj.cnipa.gov.cn/sbj/index.html, and the trademark owner must match the enterprise name.
2. Real-name requirements
- (1) Provide entity qualifications: business license / unified social credit code / institutional legal person certificate (any one). Special industries require additional permits.
- (2) Provide front and back of a valid legal representative's ID card. For public institutions and non-profits, the agent's ID card front/back is also acceptable.
- (3) The signature must reflect the corporate entity (accepted: full company name, company abbreviation, or trademark name).
Note: Pure English signatures, app names, official-account names, mini-program names, website names, software copyright names, neutral signatures, and signatures of non-mainland entities are not accepted for filing.
- (4) If authorized by a partner, provide the authorization letter and the partner's qualifications above, and the partner's name may be used as the SMS signature.
3. Notes on signature invalidation
- (1) Carriers are enforcing real-name management. Filed signatures that go unused or are sent infrequently may be cleared by carriers and become invalid, requiring re-filing. Carrier rules differ, so signatures may produce mixed results (some sent successfully, some failed).
Note: Jiguang cannot know in advance when a signature becomes invalid. Please monitor your delivery results; if you observe failures, contact Jiguang sales or support promptly.
- (2) If you send without real-name filing, any resulting failures count as carrier-side gateway blocks due to missing real-name registration. Complete the filing as early as possible.
- (3) Carrier real-name filing typically takes 3–5 working days; some carriers may take longer. We appreciate your patience.
Once again, thank you for your support and understanding. For other questions, please contact Jiguang sales or customer support at https://www.jiguang.cn/accounts/business_contact?fromPage=bot.
[2025.7.2] Notice on China Mobile and China Unicom Adding SMS Content Filing and Interception Controls
Dear SMS developers,
To regulate SMS service management and improve communications security, following China Telecom's template filing requirement, China Mobile and China Unicom have issued similar notices. The effective dates are: China Mobile from July 10, 2025; China Unicom from July 1, 2025. The control measures are:
(1) If an SMS contains contact information or links, the content must be filed with carriers for review in advance; unfiled messages will be blocked. Each SMS template can be filed with at most 1 link and 2 contact methods. In short: "file before sending." We recommend optimizing your template content in advance to avoid interception risks.
(2) Even templates without lead-generation content (such as links or contact information) may still be intercepted. Carrier execution is final.
All three major carriers have now issued SMS content control policies. We strongly recommend you avoid including "links and contact information" in SMS content, and proactively adjust to reduce interception risk.
Constrained by carrier system capabilities and shifting policies, the Jiguang platform cannot retrieve SMS content filing results from carriers. During policy enforcement, interception controls may be triggered regardless of whether filing was submitted, affecting normal delivery. In severe cases carriers may shut down "sub-ports" or "main ports", causing bulk send failures.
Jiguang will keep tracking these policies; please prepare your business response in advance.
FAQ:
1. Do all three major carriers control SMS content?
Yes. China Telecom, Unicom, and Mobile have all explicitly stated SMS content control requirements. If your SMS contains "links or contact information", it may be blocked on all three carriers and result in delivery failure.
2. How exactly is filing done?
Jiguang will organize template content per carrier requirements; compliant templates are submitted to carriers for filing. However, carriers do not provide filing-result or progress queries, so the platform cannot guarantee whether a filing action is effective.
[2025.6.3] Important Notice on Carriers Strengthening SMS Review
Dear Jiguang developers,
According to the latest policy of China Telecom Group, China Telecom may, starting May 30, 2025, gradually enforce "blocking SMS templates that have not been filed." Templates that have not been filed or have not passed carrier review may be intercepted under the new rule.
Given the tight timeline, Jiguang has begun organizing and filing SMS templates. The platform will submit your recently-sent template content to carriers per their requirements. However, due to carrier system capability and policy changes, the platform cannot obtain template filing results. Once this policy takes effect, China Telecom SMS delivery will be seriously affected — please be aware of the delivery failure risk.
1. Given this control policy and previously-enforced signature filing, we recommend you audit and adjust existing signatures and templates; new signatures and templates must also conform, to ensure normal delivery.
Signatures: strongly prefer "the full or abbreviated business-license name", followed by "app name" and "full trademark name". Signatures must be unique, non-neutral, contain no digits, contain no English characters, and so on.
Templates: templates without links, IPs, or contact information are unaffected by filing. If they do contain such content, file at most 2 contact methods, 1 link, and 1 IP address; the link and IP must belong to your own company.
Policy may change further; updates will follow carrier notices. Jiguang will continue tracking and synchronize new information promptly.
2. FAQ
1. Do all three carriers require SMS template filing?
Currently China Telecom has explicitly required full-volume template filing. China Mobile and China Unicom policies are not yet clear, but with the regulatory trend tightening, other carriers may follow.
2. When will template filing take effect and what is the policy basis?
Based on current information, China Telecom Group is expected to enforce "blocking unfiled templates" starting May 30, 2025, but no formal document has been received yet. Actual scope and timing follow the carrier's execution.
3. How is template filing done, and what information is required?
Jiguang has organized templates per the new China Telecom rule. We will extract recently-used templates and submit them to China Telecom; carriers provide no query method, so we cannot obtain filing status.
4. Where can filing status be obtained, and how long does filing usually take?
Since carriers have not opened a filing-status query channel, the timeline is hard to estimate. We recommend judging filing status through test sends.
5. If only the signature is approved but the template is not filed, does it affect normal delivery?
China Telecom's new rule uses a "block unfiled templates" mechanism. Even if the signature has been filed, unreviewed templates may still be blocked for China Telecom phone numbers per the China Telecom notice. The actual result depends on China Telecom's execution.
6. What to do if bulk delivery fails?
If you have other approved signatures/templates available, switch and test before using them. Otherwise, check whether the signature and template comply with the rules above; if not, optimize and re-submit for approval. If issues persist, contact Jiguang sales or customer support.
[2025.5.20] Announcement on China Telecom Launching Template Content Validation
Per the latest China Telecom carrier notice, starting May 30, 2025 (some provinces start May 20), the China Telecom Group will launch template content validation. Changes include:
Templates containing contact information or domain links must be re-filed; otherwise they may be blocked by the carrier system and result in delivery failure. Each SMS signature may have at most 2 contact methods and 1 domain link whitelisted; templates exceeding that need modification.
Daily from 23:00 to 07:00 the next day, China Telecom SMS channels (including verification codes) will be system-level rate limited. Normal rate resumes outside that window.
The above is a unified control measure deployed by the China Telecom Group. We will cooperate with filing as quickly as possible to maximize delivery success for China Telecom phone numbers. However, provincial execution and filing rollout differ, so interceptions or anomalies may still occur. Updates will follow carrier notices.
If you encounter SMS delivery anomalies or have other questions, contact your Jiguang business manager. Thank you for your support and understanding!
[2025.4.25] Announcement on SMS Signature Filing Procedure
Per MIIT Information Management Bureau Doc. [2023] No. 794 and Cybersecurity Bureau Doc. [2021] No. 798 on regulating port-based SMS business operations and security management, SMS content providers must file real-name qualification information.
To ensure delivery success and stability, when filing a signature, we strongly recommend in this priority: "full or abbreviated business-license name" first, then "app name" and "full trademark name". Other signature types are not currently accepted for filing.
Due to differences in carrier policy execution across regions, you may see "approved" filing results yet still encounter partial delivery failures. Please confirm signature compliance per the SMS signature reference. If the signature is not compliant, update or re-apply. If the signature is correct, we recommend sending in small batches first, then ramping up once tests meet expectations, or contact Jiguang SMS support.

[2025.3.31] Notice on Real-Name Filing for SMS Signatures and Compliance Review of Existing Signatures
Per the latest MIIT requirements on real-name management of SMS signatures, carriers have recently further tightened signature controls. To remain compliant, please complete real-name qualification filing for signatures and a compliance check of existing signatures. If a signature is unrelated to your enterprise qualifications, the existing signatures you use may face forced removal; we recommend disabling them in time and applying for new signatures to ensure normal delivery.
To comply, SMS signatures must satisfy one of the following:
1. Enterprise/institution name (recommended): must be the full name or abbreviation of the company.
Full name: the complete registered name.
Abbreviation: every character of the abbreviation must appear in the full name in order (no skipping).
2. Registered trademark: must be a trademark owned by the enterprise.
The trademark must be findable on the CNIPA trademark portal https://sbj.cnipa.gov.cn/sbj/index.html, and the owner must match the enterprise name.
3. Launched app: the signature must correspond to an existing app.
The app must be findable in MIIT's ICP/IP/Domain Filing system https://beian.miit.gov.cn/#/Integrated/index, and its ICP filing subject must match the enterprise name.
Important: If your SMS signature is unrelated to your enterprise qualification subject, new signature applications will be rejected, and existing signatures in use may largely face delivery failure. Please make timely adjustments per this notice. Thank you for your understanding and support!
