The enterprise organization code of the labor contract can be written by hand.

The organization code on the labor contract is the organization code of the contracting unit. Each registered legal enterprise has a specific and unique organization code, which is listed on the industrial and commercial registration certificate issued by the industrial and commercial administration. It is stated that some regions also have organization code certificates. At present, the integration of three certificates into one has been promoted, but the organization code of the organization remains unchanged. You can just ask your contracting unit to fill it out.
