Does a WeChat Mini Program need to be filed with the Chinese authorities?
Yes — mini programs are named in the filing regime, not exempt from it. The MIIT notice that created China’s app filing requirement defines its scope to include distribution platforms covering mini programs and quick apps (含小程序、快应用等分发), so a WeChat Mini Program is inside the same regime as a native app rather than outside it. The practical consequence is a sequencing one: for anything launched after the notice took effect, filing has to be completed before the mini program begins operating, and the provincial telecommunications authority is given 20 working days to process a complete application. That is a lead time to plan around, not a formality to attach at the end. And because a mini program that calls your own backend is also serving from somewhere, the same architecture decision raises the second question this site keeps returning to: the ICP filing that attaches to wherever those requests are actually served from. What the filing notice actually says
| Fact | Primary source |
|---|---|
The notice defines its scope to include app distribution platforms covering mini programs and quick apps — 移动互联网应用程序分发平台（含小程序、快应用等分发）. Mini programs are named in the regime rather than left outside it. | MIIT Notice 工信部信管〔2023〕105号 — 关于开展移动互联网应用程序备案工作的通知 |
| For anything launched after the notice took effect on 21 July 2023, filing must be completed before the application begins operating — not afterwards. Provincial telecommunications authorities are allowed 20 working days to process a complete application. | MIIT Notice 工信部信管〔2023〕105号 — 关于开展移动互联网应用程序备案工作的通知 |
| The regime ran on a phased timeline: preparation to the end of August 2023, filing of existing applications from September 2023 to March 2024, a compliance inspection window from April to June 2024, and ongoing management from July 2024 onward. The inspection phase has passed, so an unfiled application is now operating against a settled requirement rather than an incoming one. | MIIT Notice 工信部信管〔2023〕105号 — 关于开展移动互联网应用程序备案工作的通知 |

How Do WeChat Mini Programs and Games Launch?
WeChat launches a small program package with a maximum size of 8M to enhance loading speed. For larger games, you’ll need to host some resource files on your own server.
To start, users scan a QR code, which downloads the program package and initializes the code. Then, the code requests remote server resources, resulting in the first screen of your program or game.
How are Mini Programs different from Mini Games?
WeChat Mini Games have their category and entry points in WeChat’s game menu, along with additional APIs like leaderboards.

How To Get Started – The Hard Way
Starting your journey to develop and publish a WeChat Mini Program or Game in China can be a complex process, especially if you are not a Chinese entity. Here’s a detailed step-by-step guide on how to navigate this challenging path.
Entities Eligible for WeChat Official Accounts
| Entity | Description |
|---|---|
| Individual | WeChat users aged over 18 with a Chinese ID card and have completed real-name authentication. |
| Company | Companies, branch offices, and business-related brands. |
| Company (Individual Business) | Individually owned industrial and commercial households. |
| Government | All levels and kinds of government agencies, public institutions, and social organizations with administrative functions in China. |
| Media | Newspapers, magazines, TV stations, radio stations, and news agencies, etc. |
| Other organizations | Other entities that do not fall into the government, media, company, or individual categories. |
If you don’t fit into any of the categories mentioned above, you’ll need to explore alternative options for entering the Chinese market, such as establishing a business presence in China. Options include setting up a WFOE, forming partnerships with Chinese companies, or exploring joint ventures. These approaches can provide the necessary legal framework for your organization to publish WeChat Mini Programs or Games.
1. Register Your Developer Account and Open A New Project
The first step is to create a developer’s account with WeChat. While this process may seem straightforward, it’s essential to have a legal entity that qualifies under WeChat’s guidelines. This can be a challenging aspect, especially for non-Chinese entities.
Here’s what you need to do:
-
Go to the official WeChat account registration page.
-
Select “Mini Programs” and fill in the required information, including service category and subcategory (e.g., “Game” and “Casual Game”).
-
Prepare to submit the necessary documents and licenses. This step closely resembles the requirements for publishing native apps in China. For instance, since your server will be in China, you will need an ICP Bei’an, among other possible licenses.
-
It’s important to note that the registration process requires a 300RMB fee for verifying your company’s identity with WeChat. Be prepared for a waiting period, as approval for your official developer’s account typically takes 1-3 days. If your application is rejected, you may be contacted for additional documentation.
-
Once your account is approved, download the developer tools according to your operating system platform from the official WeChat Developer’s website.
-
In the Mini Program Management backend, register your Mini Program to obtain its AppID.
-
Open the WeChat development tools, input the corresponding AppID and project name to start your project.
-
If your Mini Program or Game involves payment processing, you must go through the process to register and verify a WeChat Pay account before you can integrate payments into your app.
This process can be demanding, but it’s a critical step in developing a WeChat Mini Program or Game. Be prepared to navigate the intricacies and legal requirements.
2. Create Your Code Files and Begin Programming
Now that you have your developer account set up, it’s time to start the technical development process. WeChat Mini Programs primarily support JavaScript and related languages like TypeScript and CoffeeScript. Additionally, the WeChat Mini Games framework provides APIs for graphics, animations, and real-time rendering.
Several Chinese game engine makers, including Cocos Creator, Egret, and Laya, support WeChat Mini Games. However, some foreign HTML5 game engines may require adaptations to work seamlessly with the platform.
One important thing to note is that you cannot use CSS and DOM during the development of a WeChat Mini Program or Game. Additionally, performance may be lower than native apps, so rigorous testing and optimization are essential to ensure a smooth user experience.
For detailed guidance, you can find official tutorials and the API documentation on WeChat’s official website.

3. Get a Mobile App ICP Filing Number
Effective from September 1, 2023, a critical new step has been introduced for all apps seeking publication on app stores in China. Now, before you can launch your app, you must undergo the ICP Filing process. For existing apps in China, it’s equally vital to obtain a valid ICP Filing Number by March 31, 2024, to ensure your app’s continued presence on app stores.
The ICP Filing process is a mandatory legal requirement in China, ensuring compliance with the country’s stringent regulations for internet content and services. It serves as a fundamental step in the journey of launching your app to the Chinese market.
For detailed guidance on how to obtain a Mobile App ICP Filing Number in China, please refer to our comprehensive guide: How To Obtain a Mobile App ICP Filing Number in China.
This step is crucial to ensure that your app meets all the necessary legal requirements and maintains its visibility on app stores within China, making it an integral part of your development process.
4. Submit Your Mini Program or Game For Approval
After you’ve completed the development of your Mini Program or Game, the next crucial step is to submit it to the WeChat team for review and approval. The approval process typically takes 1-3 days.
It’s essential to understand that the same laws and content restrictions that apply to native apps in China also apply to WeChat Mini Programs and Games. Ensure your content complies with Chinese app regulations during the development process.

By adhering to these strict regulations, you can increase the chances of a successful approval for your WeChat Mini Program or Game.

Frequently Asked Questions
Do WeChat Mini Programs need an ICP filing?
小程序 explicitly in its scope. Separately, if the mini program calls a backend you operate, whatever serves those requests is subject to the ICP filing rules for websites. The two questions are related but not the same one, and a project can satisfy one and still be exposed on the other.
