Folio Number
A folio number is a unique alphanumeric identifier assigned by an Asset Management Company to an investor at the time of the first investment in any scheme of that AMC, serving as the master account reference for all subsequent transactions across schemes of that fund house.
When an investor makes a first-time purchase in any mutual fund scheme of an AMC, the registrar and transfer agent (RTA) — either CAMS or KFintech (formerly Karvy Fintech) — assigns a folio number to that investor-AMC combination. This folio number acts as a permanent account identifier for all future transactions with that specific AMC. An investor can hold multiple schemes of the same AMC under a single folio, provided the mode of holding and KYC details are identical.
The folio number is critical for operational continuity. All purchase, redemption, switch, SIP registration, and nomination records are linked to this number. When an investor makes a fresh purchase in a different scheme of the same AMC, they can quote the existing folio number to ensure all holdings are consolidated. This simplifies tracking and reduces the need for duplicate KYC documentation.
An investor who holds schemes across multiple AMCs will have separate folio numbers for each AMC — one from HDFC Mutual Fund, another from SBI Mutual Fund, a third from Mirae Asset, and so on. This is because each AMC maintains its own investor records through its designated RTA. However, a Consolidated Account Statement (CAS) issued by NSDL or CDSL aggregates holdings across all folios into a single document, providing a unified portfolio view.
In practice, investors who make investments through different online platforms or intermediaries sometimes inadvertently create multiple folios with the same AMC, leading to fragmented holdings. This can be resolved by requesting folio consolidation directly with the AMC or through the RTA, provided KYC and mode-of-holding details match exactly. Consolidated folios make portfolio management significantly easier, especially during nomination updates or transmission of units on the death of the primary holder.
For nomination purposes, folio-level nominations are standard. SEBI mandated in 2022 that all existing folios without nominations must either submit a nomination or furnish an opt-out declaration to avoid freezing of redemption requests. This regulation underscored the importance of keeping folio-level administrative details current.
