Zerodha 12-character user ID format
A common search query is “Zerodha 12-character user ID format”. The likely intent is to look up either the Kite client ID (6 characters) or the CDSL demat account number / BO ID (16 digits), often confused. This article clarifies the identifiers and their formats.
The three identifiers
| Identifier | Format | Length | Example |
|---|---|---|---|
| Kite client ID (User ID) | 2 letters + 4 digits | 6 characters | AB1234 |
| CDSL BO ID (demat number) | 16 digits | 16 characters | 1234567890123456 |
| PAN | 10 alphanumeric (5 letters + 4 digits + 1 letter) | 10 characters | ABCDE1234F |
The “12-character” search likely conflates these.
Kite client ID
- Length: 6 characters (most accounts).
- Format: Typically 2 letters + 4 digits (varies for legacy accounts).
- Where used: Login to Kite, Console; reference for support tickets.
- Recovery: See How to look up your Zerodha client ID .
CDSL BO ID (demat number)
- Length: 16 digits.
- Format: First 8 digits are the DP-ID (Depository Participant ID); next 8 are the Client-ID at that DP.
- Where used: Demat-account-level operations (eDIS, T-PIN, transfers).
- Found: Console > Profile.
PAN
- Length: 10 alphanumeric.
- Format: 5 uppercase letters + 4 digits + 1 uppercase letter.
- Use: KYC, tax reporting, broker registration.
Why the confusion
Online search behaviour:
- Users encounter different identifiers in different contexts.
- “12-character” may be a partial recall of one of the actual identifiers.
- Different brokers historically used different formats; users mix conventions.
For Zerodha specifically, the 6-character client ID is the user-facing identifier.
Format history
Early Zerodha (circa 2010-2013): some legacy client IDs had different formats due to evolving onboarding systems. Most current accounts opened post-2014 follow the 2-letters-4-digits convention.
Where each identifier appears
| Activity | Identifier used |
|---|---|
| Kite login | Client ID (6 char) |
| Console login | Client ID (6 char) |
| Demat operations | BO ID (16 digit) |
| Tax filing (referenced) | PAN (10 char) |
| Account opening forms | All three captured |
| Support tickets | Client ID; sometimes PAN |
| Phone support verification | Client ID + PAN + DoB |
Checking your IDs
For Zerodha clients:
- Client ID: Console > Profile or via login page.
- BO ID: Console > Profile (under demat details).
- PAN: Console > Profile (verification info).
All three are visible to you in Console; share only the Client ID with support (PAN and BO ID for verification only when requested by verified support).
What to share / not share
- Client ID (6 char): Generally safe to mention in non-sensitive contexts.
- PAN: Sensitive; share only for KYC purposes.
- BO ID: Moderately sensitive; share only with depository / broker.
- TOTP / OTP / T-PIN: Never share with anyone.
