1. Shopee's submitted materials will become invalid after a period of time.

2. This is because Shopee has set a certain time limit to ensure the effectiveness and security of the platform. If the user does not submit the materials within the specified time, the system will automatically consider it invalid.

3. According to Shopee's regulations, the specific expiration time will vary depending on different circumstances. Generally speaking, if the user does not submit materials within a period of time after registration, the account will be marked as unverified and certain operations will not be possible. If materials are not submitted for a long time, the account may be deregistered or closed. Therefore, submitting the required materials in a timely manner is an important step to keep your Shopee account valid.
