RRB NTPC is one of India’s biggest recruitments, with lakhs of candidates competing for railway posts every cycle. The most common confusion about NTPC age is this: there are two post levels with two different age caps. Apply against the wrong level and your application can be rejected. This guide explains both levels, the cut-off date, and worked examples in simple words.
The two post levels and their age limits
As per recent RRB NTPC notifications, age is counted on 1 January of the exam year:
| Post level | Age limit (General) | Counted on |
|---|---|---|
| Undergraduate (12th-pass) posts | 18–30 years | 1 January |
| Graduate posts | 18–33 years | 1 January |
The minimum age is 18 for both levels. The maximum differs: 30 for undergraduate posts, 33 for graduate posts. Both limits apply on the cut-off date — not on the exam day.
Notice that the graduate level is not simply “the same rule plus three years” for everyone — it is a separate cap for separate posts. A 31-year-old graduate cannot apply for undergraduate posts even though the graduate cap is 33; the undergraduate cap of 30 still binds those posts.
Which level should you apply for?
The rule of thumb is simple: match your qualification to the level. If you have passed 12th and are not a graduate, apply for undergraduate posts. If you are a graduate, the graduate posts usually offer better pay levels — but check that your age fits the 33-year cap (or your category’s relaxed cap). Graduates who are over 33 for the General category sometimes ask whether they can “drop down” to undergraduate posts — no: the undergraduate cap is 30, which is lower, not higher.
How the 1 January cut-off works
RRB fixes 1 January of the exam year as the single date on which every candidate’s age is counted. Your age on New Year’s Day decides which posts you can apply for. The notification also prints the exact birth-date range for each level — “born not earlier than / not later than” certain dates — and that range is the final word in borderline cases. Cut-off dates are strict: even one day can change your eligibility.
Worked examples (cut-off: 1 January 2028)
(a) Undergraduate posts — born 10 June 1999 → On 1 January 2028 this candidate is 28 years old — within the undergraduate maximum of 30. Eligible by age for UG posts.
(b) Graduate posts — born 15 August 1994 → On 1 January 2028 this candidate is 33 years and about 4.5 months old — above the General graduate maximum of 33. Not eligible as a General candidate, but within the OBC effective maximum of 36 with relaxation.
(c) Graduate posts — born 31 December 1994 → On 1 January 2028 this candidate is 33 years and 1 day old — above the General graduate maximum by a single day. Cut-off dates are this strict, which is why checking your exact age matters.
Age relaxation for reserved categories
Relaxation is added to the maximum age of each level — the minimum stays 18 for everyone:
| Category | Relaxation | UG posts effective max | Graduate posts effective max |
|---|---|---|---|
| OBC | +3 years | 33 years | 36 years |
| SC / ST | +5 years | 35 years | 38 years |
| PwBD | +10 years | 40 years | 43 years |
Yes — the same relaxation applies to both levels, added to each level’s own maximum, as per the notification’s rules. Combined concessions (for example, a PwBD candidate from a reserved category) follow the notification’s own formula — do not add relaxations together yourself.

Frequently asked questions
I am 31 — can I apply for NTPC?
Only for graduate posts, and only if you are a graduate and within the 33-year cap (or the relaxed cap for your category). Undergraduate posts cap at 30.
Does the same relaxation apply to both post levels?
Yes — relaxation is added to each level’s maximum (for example, OBC +3 gives 33 for UG posts and 36 for graduate posts), per the notification.
I am a graduate but only 29. Can I apply for undergraduate posts too?
That depends on the notification’s rules for that cycle — some cycles allow applying for both levels separately. Check the notification; do not assume.
Where is the final rule written?
In the RRB notification of your cycle — the birth-date range for each post level. That document is the final authority.
