SMS sender registration in China
Prepare business SMS delivery to China with a validated sender. We review your use case, documents and route before submitting the registration.
What must be registered to send SMS to China
In China, the visible identity is handled through a brand signature and message templates must be approved before sending.
Before enabling traffic
We validate the sender, use case and authorised route for China.
Content requirements for sending SMS to China
This validation is separate from sender registration. It applies only to the scope described below.
What is registered
For mainland China, the signature identifying the entity and the message template are approved separately. Categories include OTP, transactional and promotional templates.
What to submit
Submit fixed text, variable fields, category, approved signature, use case and the business information requested by the provider or network.
If the message changes
Only approved templates may be sent with the permitted variables. A change to fixed text, purpose or structure requires another review.
Before sending
The signature and template must be approved before sending; unregistered or incompatible content may be rejected by the network.

Questions about registration in China
Is sender registration mandatory in China?
This guide covers traffic that needs prior validation or whose requirement depends on the route, network or volume. We confirm the exact scope before sending.
How long does registration take in China?
Timing depends on document review and the bodies involved. A complete request reduces follow-up, but approval is not immediate and has no single fixed timeframe.
Can I change the content or use case later?
Yes, when this guide shows additional validation: approved fixed text, structure, category or links may be tied to the registration and a material change must be reviewed.
Can recipients reply to the sender?
Alphanumeric senders are normally one-way. If you need replies in China, we will assess a compatible number or short code.
