How to Update Your Mobile Number on IRCTC Account

An outdated mobile number on your IRCTC profile isn't just an inconvenience — since so much of IRCTC's account security (OTP verification, password reset, Aadhaar linking) depends on that number being reachable, it can quietly lock you out of features you need most during a Tatkal rush. Here's how to update it.

How to Update Your Mobile Number

1. Log in to your IRCTC account on the website or app.
2. Go to "My Profile" or the account settings section.
3. Find the mobile number field and select the option to edit/update it.
4. Enter your new mobile number.
5. Complete OTP verification — sent to the new number you just entered, to confirm you actually control it.
6. Confirm the change; your profile now reflects the updated number.

Why This Matters More Than It Seems

Your registered mobile number isn't just contact information — it's the verification channel for several security-critical actions:

• Password reset: OTP-based recovery sends the code to your registered number. If that number is inactive, you can't complete password recovery through the normal self-service flow — see our account-locked guide for what happens when this compounds with a lockout.
• Aadhaar-OTP verification: completing Aadhaar KYC (required for online Tatkal, per our Aadhaar linking guide) depends on receiving OTPs, sometimes via the mobile number linked with UIDAI specifically, not just IRCTC.
• Booking confirmations and alerts: SMS confirmations for successful bookings, cancellations, and important account notices all route through this number.

A Common Trap: IRCTC Number vs Aadhaar-Linked Number

Updating your mobile number in your IRCTC profile only changes the number IRCTC itself uses — it does not automatically update the number linked to your Aadhaar with UIDAI. If your Aadhaar-OTP verification is failing specifically (as opposed to general IRCTC OTPs), the real fix is updating your number with UIDAI directly, not just in your IRCTC profile. These are two separate systems that happen to both use OTP verification, and confusing them is a common source of frustration when troubleshooting.

If You No Longer Have Access to Your Old Number

This is trickier, since the standard update flow verifies via OTP to whichever number you're trying to set — if you can't receive OTPs on either your old or new number through the self-service flow, you'll likely need to contact IRCTC customer support directly (139) for identity verification and manual assistance, since the automated flow is specifically designed to prevent number changes without OTP confirmation (a security feature, not a bug).

How Often Does This Actually Trip People Up?

It's more common than it might seem — people change phone numbers for all sorts of ordinary reasons (switching carriers, losing a phone, a work number replacing a personal one) without immediately thinking to update every account tied to that number. IRCTC often isn't top of mind until you actually need to book urgently, at which point discovering an OTP problem becomes a genuine emergency rather than a minor inconvenience. Building "update IRCTC and Aadhaar/UIDAI" into your routine whenever you change numbers avoids this entirely.

Keep This Updated Proactively

Don't wait until you're mid-booking or trying to reset a password to discover your number is outdated. If you've recently changed your phone number for any reason, updating it in your IRCTC profile (and separately with UIDAI if you rely on Aadhaar-OTP for Tatkal) should be one of the first things you do — well before you actually need the verification to work.
