Why can’t I change my WeChat number? Revealing the design logic behind WeChat
Recently, the discussion among WeChat users about "WeChat number cannot be modified" has once again become a hot topic. Many users complained that early arbitrary settings made it impossible to change, but WeChat officials have never opened the modification function. This article will analyze the reasons behind this phenomenon and compile relevant data based on the hot discussions on the Internet in the past 10 days.
1. Hot topic data on the entire network in the past 10 days

| Tik Tok | “Teach you how to hide the early Zhonger WeChat account” | 15.2 |

2. Three major technical reasons why WeChat ID cannot be modified
1.Account uniqueness anchor: WeChat official mentioned in the 2021 technical white paper that WeChat ID, as a key index field of the underlying database, is associated with the data interaction of more than 200 subsystems.
2.Risk control system dependence: The anti-fraud system will record the binding relationship between device fingerprints, behavior patterns and WeChat ID. According to a WeChat security report, fixed IDs increase fraud identification accuracy by 37%.
3.Distributed architecture limitations: WeChat adopts a sharded storage architecture. Modifying the ID requires simultaneously updating the associated data in 500+ data centers around the world, which leads to data consistency issues.
3. Conflict between user demands and official attitude

|---|---|
| Early settings contain private information | It can be solved through the "Hide WeChat ID" function |
| Hope to update with life stages | It is recommended to use "nickname + avatar" as identification |
| Enterprise accounts need to be professional | It is recommended to register a corporate WeChat account |
4. Comparative analysis of similar social products

5. Possible solutions for the future
1.Dual ID system: Distinguish between @username and display name like Twitter does, retaining the original ID as a backend identifier.
2.Paid modification service: Referring to the practice of the game industry, it can be modified at will through the payment threshold limit. Online WeChat has discussed a 198 yuan/time plan.
3.time window mechanism: Modifications are allowed during certain periods of the year, such as in conjunction with traditional festival cycles such as the Spring Festival.
The latest response from the WeChat team stated that it is developing a "historical ID tracing system" and may implement limited modification functions in future versions. However, the specific timetable has not yet been announced, and users are advised to continue to pay attention to the official announcement.
