Q. How many digits of Pincode in India are assigned to the Individual Post Offices?
Answer: last 3 digits
Notes: In India, the Postal Index Number (PIN) system consists of six digits. The first digit represents the region, the second the sub-region, the third the sorting district, and the last three digits are assigned to individual post offices. This means that the last three digits specifically identify individual post offices, making the correct answer three digits. The PIN system was introduced on August 15, 1972, to simplify mail delivery.
