Do I need to apply for this code from an official platform?

No. It is a local identifier built with a standard algorithm; the tool only provides standardized generation and validation.

How do organization and individual codes differ?

Organizations must use the unified social credit code, while individuals can use an ID card, phone number and more; the tool handles the padding logic for each ID type automatically.

Not sure how to assemble the 27-digit service provider code required by GB 45438-2025? This tool does both: enter an organization's or person's identity to generate the standard code, or paste an existing code to validate it and break down each part.

The code does not require registration with any external authority — it is generated locally from your legal identity (such as a unified social credit code, ID card or phone number) using the standard algorithm, and can be used directly for AIGC labeling.
