A dormant or inoperative bank account is one classified as inactive by the bank in line with Reserve Bank of India (RBI) guidelines, typically when there are no customer-induced transactions for an extended period. An account is generally treated as inactive after 12 months of no such transactions and reclassified as inoperative beyond 24 months, with restrictions then applying to cheque book usage, debit cards, and digital banking access. Customers can reactivate an inactive or dormant account as per RBI guidelines by visiting an ICICI Bank branch and submitting fresh KYC documents in original. This page lists category-wise documentation for Individual, Non-Individual, Fixed Deposit, and Non-Resident Accounts, along with the applicable restrictions in an inoperative account. To prevent dormancy, refer to the "How to avoid this" section for simple steps such as maintaining regular transactions and keeping your KYC details updated.
