How this works
Indian Railways allots berths using a repeating pattern per coach type — eight seats to a bay in Sleeper and AC 3-Tier, six in AC 2-Tier, and a straight row in chair-car classes. Your seat number's position in that pattern decides whether you get a Lower, Middle, Upper or Side berth, and whether you're at window height. Pick your class above, or type the seat number straight in — the diagram and the panel show the same answer the conductor's chart would.
Frequently asked
- What does the seat number on my IRCTC ticket mean?
- IRCTC prints only a coach and seat number, like S4, 45 — it doesn't say whether that's a lower, middle, upper or side berth, or whether you're near a window. This tool decodes it instantly using the same bay pattern Indian Railways uses to allot berths.
- How do I know if my seat has a window?
- Only Lower and Side Lower berths sit at seated eye level with a real view — Middle and Upper berths are above the window line even though the bay itself has a window. Search your seat number above to see which one you have.
- What's the difference between Side Lower and Side Upper berth?
- Side berths run along the coach's outer wall, facing the aisle instead of a facing bay. Side Lower sits at seat height with a window view and the least climbing; Side Upper is above it, folded away in the day.
- What's the difference between 3A and 3E coaches?
- 3A (AC 3-Tier) and 3E (AC 3-Tier Economy) use the same lower-middle-upper pattern, but 3E packs nine berths into a bay instead of eight, so it's narrower and carries a small side section instead of a matching side pair.
- Does this tool need my PNR?
- No. Enter only your coach type and seat number — nothing is looked up on IRCTC's servers, and nothing about you is stored.
- Where's the charging point in Sleeper class?
- Sleeper (SL) has charging points only at Lower and Side Lower berths, one socket usually shared between two adjacent berths. AC classes give every berth its own socket.
No account, no PNR needed — just your coach type and seat number.
