Tatkal booking opens one day before the train departs from its originating station, excluding the journey date. AC bookings begin at 10 AM, while Sleeper and other non-AC Tatkal bookings begin at 11 AM.

Passengers booking online should complete their IRCTC Aadhaar authentication in advance. Tatkal seats are limited, and booking at the opening time does not guarantee a confirmed ticket.

Tatkal Ticket Booking 2026: Book Confirmed Train Tickets for Diwali and Chhath, Check IRCTC Rules

IRCTC Tatkal Ticket Booking 2026: With Diwali and Chhath approaching, railway passengers travelling to their hometowns may find it difficult to secure confirmed train reservations. Demand typically increases on popular routes during the festive season, and seats can fill up well before the journey date.

For passengers who could not reserve tickets through the regular booking system, Indian Railways offers the Tatkal reservation facility.

Under this arrangement, a limited number of seats are made available shortly before a train's scheduled departure.

However, passengers must follow specific booking timings, Aadhaar authentication requirements and payment procedures.

Understanding these rules in advance can help travellers avoid mistakes when the reservation window opens.

Tatkal Ticket Booking Time: AC and Sleeper Classes

Tatkal reservations open one day before the train's departure date from its originating station, excluding the departure day.

The opening time depends on the travel class.

All timings are in Indian Standard Time.

Tatkal availability depends on the selected train, class and journey segment. Not every train or class offers a Tatkal quota.

When Should You Book Your Tatkal Ticket?

Suppose a train is scheduled to leave its originating station on October 28, 2026.

Its Tatkal booking window will generally open on October 27.

Passengers booking an AC class can attempt reservations from 10 AM, while Sleeper Class bookings begin at 11 AM.

One important point is that the booking date is determined by the train's departure from its originating station.

If a passenger boards the train at an intermediate station on a later date, the Tatkal opening date may still be based on the train's original departure date.

Travellers should check the train schedule carefully to avoid missing the booking window.

Aadhaar Authentication Is Mandatory for Online Tatkal Booking

Indian Railways introduced stricter identity verification requirements for Tatkal reservations in 2025.

From July 1, 2025, only Aadhaar-authenticated users have been permitted to book Tatkal tickets through the official IRCTC website and mobile application.

Aadhaar-based OTP authentication was also made mandatory for online Tatkal bookings from July 15, 2025.

Therefore, passengers should complete Aadhaar verification before the day they intend to book.

Waiting until the reservation window opens to authenticate an account could result in unnecessary delays.

How to Verify Aadhaar on IRCTC

Passengers can authenticate their IRCTC account through the official website or Rail Connect mobile application.

The general process is:

1. Log in to your IRCTC account.
2. Open the account or profile section.
3. Select the Aadhaar authentication facility.
4. Check whether the profile details match your Aadhaar information.
5. Enter the Aadhaar number or Virtual ID through the prescribed process.
6. Complete the OTP verification sent to the Aadhaar-linked mobile number.
7. Confirm that the account shows successful Aadhaar authentication.

Passengers should ensure that the required mobile number is active and accessible.

How to Book a Tatkal Ticket on IRCTC

Once Aadhaar authentication is complete, passengers can follow these steps.

Step 1: Log In Before the Booking Window

Visit https://www.irctc.co.in/ or open the official IRCTC Rail Connect app.

Sign in using your registered credentials.

Keep your account details ready before the booking time.

Step 2: Enter Your Journey Details

Select the departure station, destination and intended journey date.

Search for available trains on the route.

Step 3: Choose the Tatkal Quota

Select the train and travel class.

Choose Tatkal from the available quota options.

Check whether seats are available for the selected journey.

Step 4: Enter Passenger Information

Provide the required passenger details accurately.

Check names, ages, travel preferences and other requested information.

Step 5: Complete Verification

Follow the applicable Aadhaar-based OTP authentication process.

Enter the verification code only on the official IRCTC platform.

Step 6: Make Payment

Choose an available payment method and complete the transaction promptly.

Avoid refreshing the page unnecessarily while payment is processing.

Step 7: Check the Ticket Status

After booking, verify the PNR number and reservation status.

A successful payment does not by itself establish that a confirmed berth has been allotted.

Passengers should check the final ticket details.

Maximum Four Passengers on One Tatkal Ticket

Indian Railways allows a maximum of four passengers to be booked under one Tatkal PNR.

Families travelling in larger groups may therefore need more than one reservation.

However, separate bookings do not guarantee seats in the same coach or nearby berths.

Passengers should consider this limitation when making festive travel arrangements.

Tatkal Tickets Cost More Than Regular Tickets

Tatkal tickets generally include additional charges beyond the normal applicable fare.

These charges vary according to the travel class and prescribed minimum and maximum limits.

Passengers should review the total payable amount before confirming their reservation.

Other applicable charges may also be reflected during the booking process.

The final fare displayed by IRCTC should be treated as the payable amount for the selected reservation.

Can You Get a Refund After Cancelling a Tatkal Ticket?

Refund rules for Tatkal tickets differ from those applicable to ordinary reservations.

As a general rule, passengers who voluntarily cancel a confirmed Tatkal ticket do not receive a refund.

However, specified exceptions may apply under railway refund rules, including certain train disruptions and qualifying circumstances.

Waitlisted Tatkal tickets are subject to the applicable cancellation and refund provisions.

Passengers should therefore verify their journey plans carefully before paying for a confirmed Tatkal reservation.

New Rules for Authorised Railway Ticket Agents

Indian Railways also introduced restrictions on authorised agents during the opening period of Tatkal reservations.

Under the rules announced in 2025, authorised agents cannot book opening-day Tatkal tickets during the first 30 minutes of the booking window.

The restriction is intended to provide individual passengers with an opportunity to access newly released Tatkal seats before authorised agents enter the booking process.

For Tatkal bookings through authorised agents or computerised railway reservation counters, the prescribed OTP verification process also applies.

Tips to Improve Your Chances of Booking a Tatkal Ticket

Tatkal seats can sell out quickly on heavily travelled routes.

Passengers should prepare their accounts and journey information in advance.

Keep these points in mind:

• Complete IRCTC Aadhaar authentication before the booking day.
• Ensure access to the mobile number needed for OTP verification.
• Check the train's originating-station departure date.
• Keep passenger details accurate and ready.
• Choose a reliable internet connection.
• Make sure sufficient funds are available for payment.
• Check alternate trains and classes if your preferred option is unavailable.

These precautions may help avoid delays, but they do not guarantee a confirmed reservation.

What If Tatkal Tickets Are Also Unavailable?

Passengers can check other trains operating on the same route.

They may also consider nearby boarding or destination stations, provided the journey arrangement is practical and permitted.

Indian Railways sometimes operates special trains during periods of increased demand.

Travellers can check official railway announcements and IRCTC availability for such services.

If a ticket remains waitlisted, passengers should understand the applicable travel rules before boarding.

In particular, a fully waitlisted IRCTC e-ticket that remains waitlisted after chart preparation does not authorise travel in a reserved coach.

Final Update

Tatkal reservations offer an additional opportunity for passengers who could not secure regular train tickets for Diwali and Chhath.

AC Tatkal bookings open at 10 AM, while Sleeper and other non-AC bookings begin at 11 AM, one day before the train leaves its originating station.

Online Tatkal passengers must use an Aadhaar-authenticated IRCTC account and complete the prescribed OTP verification.

With limited seats available, checking the correct booking date and preparing payment and passenger details in advance can make the process smoother.
