📋 What is PNDT Number?

• It is the registration number allotted by the Appropriate Authority (AA) under the PC-PNDT Act, 1994.

• This number legalizes the use of the imaging machine (X-ray, CT, MRI, USG) for diagnostic purposes and confirms that the center is not misusing it for sex determination.

• It is machine-specific & center-specific → if a hospital has CT + MRI + Ultrasound, each must be registered separately and PNDT numbers are issued for each.

🔹 Format of PNDT Number

The PNDT number generally looks like this (may vary state to state):

PNDT/STATE/DISTRICT/CENTER-ID/Year

👉 Example:
PNDT/MH/Pune/1234/2025

• PNDT → Act name

• MH → State code (Maharashtra)

• Pune → District

• 1234 → Facility registration number

• 2025 → Year of issuance/renewal

🔹 For CT & MRI Machines

• Both CT and MRI must be registered under PNDT if used for pre-natal diagnosis / obstetric imaging.

• If the hospital/center does not perform fetal scans, still many district health authorities issue a PNDT registration number as a precautionary requirement.

• The PNDT number is then displayed on all reports, forms, and boards in the radiology department.
