For UP Police (UPP) recruitment exams, the eligibility criteria depend on the specific position you're applying for. Generally:

1. Constable Posts : The minimum age is typically 18 years , and the maximum age is around 22 years (with relaxations for reserved categories).
2. Sub-Inspector (SI) Posts : The minimum age is generally 21 years , and the maximum age is around 28 years (with relaxations for reserved categories).

Since your date of birth is 11 December 2007 , you will turn:

• 18 years old on 11 December 2025 , making you eligible for constable-level posts if the recruitment occurs after that date.
• 21 years old on 11 December 2028 , so you won’t be eligible for SI posts until then.

If you're targeting constable posts, check the specific notification to ensure your eligibility based on the exact recruitment dates in 2025.
