Folio
A folio is your unique account number with a particular AMC, under which all your investments, SIPs, and transactions in that fund house are recorded.
A folio number is essentially your customer ID with one fund house. It is the single reference that ties together everything you hold with that AMC, just as a bank account number identifies your relationship with a bank. Quote it to check your balance, track an SIP, or raise a service request.
How it works
One folio can hold multiple schemes of the same AMC, so all your SBI funds, for instance, can sit under a single SBI folio if you invest using the same PAN, bank account, and holding details. The folio records your units, transaction history, nominee, and bank mandate. Each separate AMC you invest with gives you a different folio, so an investor spread across five fund houses will have at least five folios.
In India
Folios are maintained by the AMC, but the record-keeping is largely handled by two registrar and transfer agents (RTAs): CAMS and KFintech, which between them service most Indian fund houses. A common annoyance is ending up with multiple folios within the same AMC, which can happen if you invest through different platforms or with slightly mismatched details. You can ask the AMC to consolidate them for cleaner tracking.
The PAN advantage
Whatever folios you accumulate, your PAN stitches the whole picture together. The Consolidated Account Statement (CAS), generated through CAMS and KFintech, shows all your mutual fund holdings across every AMC in one document, linked by PAN. This is the easiest way to see your complete portfolio without logging into each fund house separately.
Why it matters
Keeping your folios tidy makes life easier at redemption, during tax filing, and for your nominees. Scattered or duplicate folios with inconsistent nominee and bank details are a common cause of delays and unclaimed investments. Use the same PAN and bank account across investments, consolidate duplicates, and review your CAS periodically so nothing in your portfolio gets lost or forgotten.
