## How should you choose?

1. Decide whether you need contact details (email, mobile) or only firmographics such as category, location and registration data.
2. Check where the records come from. Registry-based lists are accurate on status and address; contact fields decay by about 2 percent a month by one vendor's estimate, so verify before sending.
3. Compare per-record prices: published rates run from INR 0.40 per call to INR 349 per report in this review.
4. Check data protection duties under India's DPDP Act before you contact people from a purchased list.
5. If an AI agent will build the list, prefer a public MCP server with OAuth sign-in.

## Frequently asked questions

### What is the best B2B company databases in India?

IndiaCos ranks first for B2B company databases on the JurisGrid rubric, with plain English list building over companies, LLPs and GST registrations at INR 0.40 per successful call. InstaFinancials and Tofler follow with per-report prices, and EasyLeadz is the contact finder with a published monthly price. Match the choice to your use case.

### What is the difference between a company database and a lead list?

A company database holds registry facts such as name, status, address, industry and directors. A lead list adds contact details for people, such as work email or phone. Registry data is public and stable; contact data goes stale faster and carries data protection duties, so verify it before you send.

### Which B2B company databases in India have an MCP server?

IndiaCos lists a public MCP server in this review. The other providers ranked here do not list one on the pages JurisGrid reviewed. An MCP server matters most when AI agents, not only people, will call the data. Check each provider's tool list before relying on it, since tool counts and billing differ.

### Which B2B company databases in India publish prices?

IndiaCos, Tofler and EasyLeadz publish prices in this review. The others quote on request, sell by subscription without a price list or publish nothing on the pages reviewed. Published prices let you estimate a bill before you contact anyone. Prices change, so confirm them on the provider's pricing page.

### Which B2B company databases in India can you start using without a sales call?

IndiaCos, InstaFinancials, Tofler, EasyLeadz and Zauba Corp offer self-serve sign-up in this review. IndiaCos gives INR 50 free credit on signup. Providers that route sign-up through sales may still be strong choices for managed or enterprise needs. Sign-up routes change, so confirm them on each provider's site.

### How does JurisGrid rank B2B company databases in India?

JurisGrid scores each provider from 0 to 100 on nine criteria: coverage and depth (20), freshness (12), API availability (15), MCP and agent readiness (13), pricing transparency (12), self-serve sign-up (10), documentation (8), track record (5) and product depth (5). Rankings follow the score and use only public evidence.
