Two people can hold the same RAC number and have different odds — because the *class* they booked changes everything. Here is how RAC confirmation chances work in Sleeper (SL), 2AC and 3AC, so you can judge your real position.

How RAC Clears (the Basic Rule)

RAC (Reservation Against Cancellation) gives two passengers a shared side-lower berth. As confirmed passengers cancel, the top RAC positions upgrade to full berths and everyone below moves up. This happens through rolling cancellations before travel and again at chart preparation. So a lower RAC number is closer to confirmation in every class — but how fast it moves depends on how many berths (and cancellations) that class has. For the basics, see what an RAC ticket means.

RAC Confirmation Chances in Sleeper (SL)

Sleeper coaches have the most berths and the most RAC seats, and they also see the highest volume of cancellations. That means:

• RAC 1–20 in Sleeper — strong chances; most confirm by chart preparation.
• RAC 20–50 — good on busy long-distance trains.
• High RAC (50+) — you can still board and travel on the side-lower berth even if it does not upgrade.

Because Sleeper has the biggest quota, RAC here generally moves well.

RAC Confirmation Chances in 3AC

3AC has fewer berths than Sleeper, so a smaller RAC quota — but it also sees steady cancellations. As a rough guide:

• RAC 1–10 in 3AC — very good; usually confirms.
• RAC 10–25 — moderate to good, depending on route and season.
• Higher RAC — clears mainly on popular, high-turnover routes.

RAC Confirmation Chances in 2AC

2AC has the fewest RAC seats of the three, because the coach has fewer berths overall. Fewer RAC positions means the queue is short, so:

• RAC 1–6 in 2AC — strong chances of upgrading to a full berth.
• Beyond that — confirmation depends heavily on cancellations, which are fewer in this premium class.

Note that 1AC generally has no RAC at all — bookings there go straight to the waiting list.

Why Route and Season Matter as Much as Class

A busy long-distance train clears RAC far faster than a short, lightly booked one, and festival or holiday trains see fewer cancellations, so RAC moves slower. That is why the same RAC number confirms easily on one train and stays put on another. For the number-by-number view, read RAC 1 to RAC 100 explained.

Check Your Real Chances

Don't guess by class alone — enter your PNR on our PNR status tool to see your RAC number and a confirmation prediction for your exact train, then confirm the final berth on our confirm berth tool after charting.

Bottom line: Sleeper clears RAC most easily (biggest quota), 3AC is solid at low numbers, and 2AC has the fewest RAC seats but a short queue — in every class, a low RAC number is your friend, and you can travel regardless.
