The Machine Readable Passport system relies on data from NADRA's system, ensuring accuracy and efficiency in the application process. It's crucial to note that an application can only be processed if the applicant possesses a valid original Computerized National Identity Card (CNIC), National Identity Card for Overseas Pakistanis (NICOP), or Smart ID Card. These identity documents serve as essential prerequisites, ensuring a secure and reliable passport issuance process. Applicants are advised to have their valid identification cards ready before initiating the passport application to facilitate a smooth and successful transaction.
