BOID in Zerodha is your Beneficiary Owner ID (also called BO ID or Demat ID), a unique 16-digit number that identifies your Demat account with CDSL through Zerodha.

It's essential for managing securities like stocks and mutual funds securely.

Quick Scoop

Your BOID combines Zerodha's DP ID (first 8 digits, identifying the broker) and your Client ID (last 8 digits, unique to you). For example: 1208160002420841 , where 12081600 is the DP ID and 02420841 is your specific client part.

This isn't the same as your Zerodha login Client ID (like ZY0123)—BOID is strictly for Demat holdings.

"A BO ID in Zerodha is like your digital identity card in the world of stock trading. This 16-digit code links your Demat account to the securities you hold."

Why BOID Matters

BOID proves ownership of your investments and enables key actions:

  • Transactions : Buying, selling, or transferring shares requires it for settlement.
  • Corporate Benefits : Dividends, bonuses, or rights issues credit to your BOID.
  • TPIN Authorization : Generate a CDSL TPIN for off-market sales using your BOID.
  • IPOs & Compliance: Needed for applications and SEBI-regulated tracking.
  • Security : Creates an audit trail to prevent fraud.

Without it, you can't authorize sells or receive holdings updates.

How to Find Your BOID

Finding it is straightforward on Kite (web/mobile)—no calls needed. Here's how, step by step:

  1. Kite Web : Log in > Profile (top-right) > View your profile > Scroll to Account details > BO ID listed there.
  1. Kite Mobile App : Menu (hamburger icon) > Profile > Account details > BO ID displayed prominently.
  1. Console : Log in to Zerodha Console > Profile > Demat account section shows full BOID.

Pro tip: Note it down or screenshot—it's static forever.

Common Confusions & Myths

  • BOID vs. Client ID : BOID = Demat (holdings); Client ID = Trading login. Don't mix them!
  • Not Bracket Order : One source confuses it with trading "BO ID," but that's outdated—standard meaning is Demat BOID.
  • CDSL Only : Zerodha uses CDSL (not NSDL), so BOID starts with their DP prefix.
  • No Changes : It never expires or updates unless you open a new Demat.

Forum chatter on Reddit/Quora often asks this during onboarding—trending since 2024 app updates made it easier to spot.

Real-World Example

Imagine buying 100 Reliance shares: They credit to your Demat via BOID. Later, selling? Enter BOID on CDSL site for TPIN approval. Simple, secure—no middleman risks.

As of March 2026, no major changes; Zerodha's support still points to Profile for it.

TL;DR : BOID is your 16-digit Demat ID in Zerodha—find it in Profile on Kite. Vital for holdings, trades, and TPIN.
