Integration of director identification consolidates DIN/DPIN use and mandates PAN submission to retain identifier status. Integration of the Director's Identification Number (DIN) and Designated Partnership Identification Number (DPIN) makes the existing identifier useable for both company director and LLP designated partner purposes; no fresh DPINs will be issued and individuals must obtain DIN by filing e-form DIN 1 where required. Holders must furnish PAN via e-form DIN 4 within the prescribed timeline or face disabling of the identifier and penalties.
