Bank of India (BOI) has published a notice in the Business Standard (English and Hindi editions) and Loksatta (Marathi newspaper) on April 9, 2026, regarding a Special Window for the transfer and dematerialisation of physical securities. This special window, operational from February 5, 2026, to February 4, 2027, is for shareholders who had transfer deeds lodged prior to April 4, 2019, but were rejected, returned, or not attended due to deficiencies. Shareholders can submit their documents to the Bank's Registrar and Share Transfer Agent, Bigshare Services Pvt. Ltd., at their Mumbai office. The bank also urges shareholders to update their KYC details, including PAN, email, address, and bank account information, with their Depository Participant (DP) if shares are held in demat form, or with the Registrar and Transfer Agent (RTA) if shares are held in physical form. This is to ensure smooth communication and dividend payments. Shareholders holding shares in physical form are encouraged to dematerialize them by submitting their share certificates to their DP.
