Change in cin due to change in state of regd office

Dear All,

Can you please let me know whether CIN (company identification number) changes when a company changes its registered office from one state to another.

In any case, does any component of the original CIN remain intact in the new CIN if it is changed.

In case CIN does change, is there a systematic way to find new CIN if we only know the old CIN of the company.

Thanks

Ashok Garg
