According to sources, the software identified suspicious CNICs by analysing family compositions and tracing inconsistencies.

The investigation revealed that a large number of Afghan nationals had been illegally added to the family trees of Pakistani citizens residing in Pishin, Chaman, and Quetta.

Officials said local agents allegedly facilitated the inclusion of these Afghan nationals in Pakistani family records in exchange for hefty payments. Many citizens were reportedly unaware that their family data had been misused.

Sources added that NADRA has now begun automatically blocking fake identity cards flagged by the system.

Holders of blocked CNICs have been instructed to visit NADRA offices for verification, and cards not verified within the given timeframe will be permanently cancelled.
