IRCTC SMS Alert Service: How to Enable It

Not every journey happens with a smartphone and a full data connection handy. IRCTC's SMS-based services exist for exactly that gap — checking status, getting booking confirmations, and receiving journey alerts on any basic phone.

Booking Confirmation by SMS

Any time you book a ticket on IRCTC with a valid mobile number linked to your account, you automatically receive an SMS with your PNR, train details and booking status — no separate opt-in needed for this part. It's the same SMS that TTEs will often accept alongside ID proof if you don't have a printed ticket.

Checking PNR Status by SMS

Send an SMS in the format PNR <10-digit PNR number> to 139 from any phone. You'll get your current status back as a text within a minute — this works with zero data connection, anywhere you have basic mobile signal.

Checking Train Running Status by SMS

Similarly, send your train number in the required format to 139 to get live running status and delay information back by text — see our full running-status guide for the exact syntax and alternatives.

Journey Reminder Alerts

Beyond PNR and status checks, some SMS-based reminder services (including third-party tools and IRCTC's own alerts where enabled) can notify you ahead of departure or when your waitlisted ticket's status changes — useful if you don't want to keep manually checking as your journey date approaches.

139 by Voice, If You'd Rather Not Text

The same 139 number also works as a voice IVR service — dial it and follow the prompts for PNR status, running status, or general enquiry, if typing an SMS isn't convenient.

Why This Still Matters in the App Era

SMS-based checking remains genuinely useful in low-connectivity areas — smaller towns, trains passing through weak-signal stretches, or simply a phone running low on battery where opening a data-heavy app isn't practical. It's slower than an app, but it works almost everywhere a phone call would.
