# How do I tell which fund house an Indian SIF belongs to?

**By the ISIN prefix, because nothing else will tell you.** Two things make this genuinely confusing, and both are by design.

- **The names are unfamiliar on purpose.** SEBI requires a Specialized Investment Fund to carry a distinct brand name and logo, separate from the AMC's regular mutual fund business. So ICICI Prudential's SIF is called **iSIF**, SBI's is **Magnum**, Kotak's is **Infinity** - and a list of SIF fund houses reads like a list of companies you have never heard of.

- **The SIF code is a running number** and nothing more. It identifies the scheme; it says nothing about the sponsor.

**The ISIN carries the answer.** Each SIF scheme's ISIN starts with the sponsor's issuer prefix - the same first seven characters that sit on that AMC's regular mutual fund ISINs. `INF174K` is Kotak on a SIF scheme and on a Kotak mutual fund alike; `INF109K` is ICICI Prudential; `INF200K` is SBI. This is an observed regularity rather than a documented guarantee - it held on all 17 fund houses when checked - so treat it as reliable and verify on anything that matters.

**If you work with this data, build the mapping once and keep it.** Seventeen rows, prefix to AMC, and you only redo it when a new fund house turns up. The scheme master in the free SIF dataset carries the ISINs, so you can build it straight off the download: [sif.tigzig.com](https://sif.tigzig.com), CSV and Parquet, refreshed twice a day, no key.
