Best company check and GST verification tools in India (2026)

Written by the IndiaCos team. IndiaCos is our product, so we have put it first; we have tried to describe every other product fairly, using only what each company says on its own website (checked 24 October 2026). Features and prices change, so check each site before you decide. Spotted an error? Tell us and we will fix it.

There are several good company check and GST verification tools available in India, and the right one depends on what you are trying to do. Below are 6 options we think are worth knowing, starting with our own, IndiaCos. For each one we say what it is, who it suits and what to keep in mind.

How we picked

We included products that are live, clearly relevant to Indian users, and described in enough detail on their own websites for us to summarise them accurately. We looked at four things:

• Fit for the job: what problem the product is built to solve.
• Transparency: whether it shows where its information comes from.
• Access: whether you can start free, and whether software and AI assistants can use it.
• Who it suits: individuals, professionals, small businesses or enterprises.

We put IndiaCos first because it is our product and because it scores well on transparency and free access. The others are listed in no particular order of quality; each is the better choice for some users.

Reports are free to read, with JSON through an API and an MCP server.

Best for: a free, fast pre-deal check that combines company, GST and court records.

How to choose

1. Write down the one job you need done. Each product here is strongest at something different.
2. Test with a real case. Run the same search or request on two or three options and compare the answers.
3. Check the source. Prefer tools that show where each fact came from, especially for money, legal or hiring decisions.
4. Look at total cost. Free tiers are useful; read the paid plans before you commit a team to one tool.
5. Think about automation. If you want software or an AI assistant to use the data, check for an API or MCP server.
