From WebNotes, a public knowledge base. Last updated 19 June 2026. Reading time ~9 min.

Key facts

Time required	Same day if you switch to the offline route; longer if you link the mobile to Aadhaar first
Cost	Rs 50 Aadhaar mobile-update fee at an Aadhaar Seva Kendra, plus Zerodha account-opening charges for the chosen route
Documents needed	PAN, Aadhaar, bank proof, signature, and a courier for the offline route

Procedure

Confirm whether your mobile is linked to AadhaarThe Zerodha online flow sends an eKYC OTP to the mobile registered with Aadhaar. If you never receive that OTP, the number on your Aadhaar record is not your current mobile, and the online route cannot proceed.
Choose between linking the mobile and going offlineEither link your current mobile to Aadhaar at an Aadhaar Seva Kendra and then open online, or skip Aadhaar OTP entirely and open through Zerodha’s offline route. The offline route is faster to start; linking keeps the fully online experience.
Link your mobile to Aadhaar at an Aadhaar Seva KendraVisit a UIDAI Aadhaar Seva Kendra in person with your Aadhaar, give a biometric, and request a mobile-number update. The fee is Rs 50 and the new number reflects in the UIDAI database within a few days.
Or start the Zerodha offline account-opening routeOn signup.zerodha.com choose the offline option, fill the application, print the forms, self-attest the document copies, sign, and courier the set to Zerodha’s office in Bengaluru for in-person verification.
Complete verification and fund the accountFor the online route, complete Aadhaar e-sign and the in-person video verification once the OTP works. For the offline route, await processing of the couriered forms. After approval, set your Kite password and add funds.

Zerodha’s online account opening runs on Aadhaar-based eKYC, and that step sends a one-time password to the mobile number recorded against your Aadhaar. If your current mobile is not the number on your Aadhaar record, the OTP never arrives and the online flow stops at verification. This guide covers the two genuine ways forward: link your current mobile to Aadhaar at an Aadhaar Seva Kendra and then open online, or skip Aadhaar OTP and open through Zerodha’s offline route. It also covers the trade-offs between them.

There is no OTP workaround inside the online flow. The eKYC OTP is integral to UIDAI Aadhaar verification, so a missing Aadhaar-mobile link is not a Zerodha bug to route around; it is a UIDAI record that either gets updated or gets bypassed by going offline. Zerodha’s own support guidance says the same: get the Aadhaar updated, or open the account in offline mode.

Step-by-step procedure

The procedure infobox above lists the five-step decision-and-execution path. The H3 subsections below expand each step, name the UIDAI and Zerodha touchpoints precisely as of 19 June 2026, and set out which route fits which situation.

1. Confirm whether your mobile is linked to Aadhaar

Begin the online signup at signup.zerodha.com and reach the Aadhaar eKYC step. Zerodha sends the eKYC OTP to the mobile registered with UIDAI, not to the number you typed into the signup form. If you receive the OTP, your mobile is linked and you can open the account online in the usual way described in how to open a Zerodha account . If no OTP arrives, the Aadhaar-mobile link is missing or stale, and you pick one of the two routes below.

2. Choose between linking the mobile and going offline

The decision is a trade-off of speed against the online experience. Linking your mobile at an Aadhaar Seva Kendra takes a centre visit and a few days for the UIDAI database to update, after which the entire Zerodha flow runs online and paperless. The offline route starts the same day with no UIDAI visit, but it replaces the paperless eKYC flow with printed forms, wet signatures, and a courier. Choose linking if you want the online flow and can wait a few days; choose offline if you need to start now or do not want to update your UIDAI record.

3. Link your mobile to Aadhaar at an Aadhaar Seva Kendra

A mobile-number update on Aadhaar cannot be done online; UIDAI requires an in-person biometric for it. Locate the nearest Aadhaar Seva Kendra through the UIDAI portal at uidai.gov.in , carry your Aadhaar, give the fingerprint or iris biometric at the counter, and ask the operator to update the mobile number. The fee is Rs 50. The number reflects in the UIDAI database within a few days, after which the Zerodha eKYC OTP reaches your phone and you complete the online flow.

4. Or start the Zerodha offline account-opening route

If you skip the Aadhaar update, choose the offline option at signup and follow how to open a Zerodha account offline . You fill the application, print the account-opening and CDSL KYC forms, self-attest the copies of your PAN and address proof, sign every page so the signature matches your normal one, and courier the set to Zerodha’s customer support office in Bengaluru. Offline opening uses physical document verification in place of Aadhaar OTP, so the missing Aadhaar-mobile link is not an obstacle on this route at all.

5. Complete verification and fund the account

On the online route, once the OTP works after linking, complete the Aadhaar e-sign and the in-person video verification, then set your Kite password and add funds. On the offline route, await processing of the couriered forms; once Zerodha approves the application, your login is activated and you fund the account the same way. From this point both routes converge on the same Zerodha account.

If you want to proceed once you have settled the route, you can open a Zerodha account and select the online or offline path at signup.

Why the Aadhaar-mobile link matters for eKYC

UIDAI Aadhaar eKYC authenticates you by sending an OTP to the mobile in your Aadhaar record and matching it to your consent. The broker never sees your Aadhaar password or biometric; it relies on UIDAI confirming the OTP. That design is why Zerodha cannot send the OTP to an arbitrary number you supply, and why a number absent from your UIDAI record breaks the chain. For the broader contrast between the OTP-driven paperless flow and the physical-document flow, see Zerodha eKYC versus offline KYC .

The same link governs the Virtual ID e-sign alternative. Even when you e-sign the forms with an Aadhaar Virtual ID instead of the raw Aadhaar number, the e-sign still authenticates through an OTP to the Aadhaar-linked mobile, so a Virtual ID does not bypass the missing-link problem. Linking the mobile or going offline remain the only two answers.

DigiLocker and where it fits

DigiLocker can supply the documents that a KYC flow needs, but accessing your own DigiLocker is itself gated by an OTP to the Aadhaar-linked mobile during sign-up. DigiLocker therefore helps with document fetch once you are already authenticated, not with the underlying problem that your mobile is not on your Aadhaar record. It does not substitute for the eKYC OTP at account opening. Treat it as a document source, not as a route around the missing link.

Documents and charges by route

Both routes need the same identity set: PAN, Aadhaar, a bank proof such as a cancelled cheque or recent statement, a signature, and a photograph. The full list is in documents required for a Zerodha account . The link-first route adds the Rs 50 UIDAI mobile-update fee on top of Zerodha’s account-opening charges . The offline route adds the courier cost. Neither route changes the recurring costs once the account is live, covered in Zerodha charges and the demat AMC charge .

What can go wrong

Waiting for an OTP that will never come. If your mobile is not on your Aadhaar record, no amount of resending the eKYC OTP will work. Diagnose this early at step one rather than retrying the online flow.
Assuming the mobile update is online. A UIDAI mobile-number change requires an in-person biometric at an Aadhaar Seva Kendra. There is no online self-service for it, so plan a centre visit.
Mismatched signatures on offline forms. Zerodha rejects offline forms where the signature does not match. Sign exactly as you sign elsewhere on identity documents.
PAN not linked to Aadhaar. A PAN that is inoperative for want of Aadhaar linkage will fail KYC on either route. Resolve PAN-Aadhaar linking before you start.
Expecting DigiLocker to skip the OTP. DigiLocker sign-up also needs the Aadhaar-linked mobile OTP, so it does not bypass the missing link. Use it only as a document source after you are authenticated.
