"FIA arrested Sharbat Gula, an Afghan woman, for obtaining a fake ID card," Shahid Ilyas, an official of the National Database Registration Authority (NADRA), said.
Mr Ilyas said the authorities were also seeking three NADRA officials found responsible for issuing Pakistan's national identity card to Ms Gula, who have been at large since the fraud was uncovered.
He said that Ms Gula faces seven to 14 years in prison and a fine of US$3000-US$5000 if convicted.
In reality she is unlikely to serve such a harsh sentence - many Afghans who have been convicted in similar cases have been deported before they could be sent to prison.
Officials say Ms Gula applied for a Pakistani identity card in Peshawar in April 2014 using the name Sharbat Bibi. Thousands of Afghan refugees have managed to dodge Pakistan's computerised system to get an identity card.
The photo attached to her application featured the same piercing green eyes seen in Mr McCurry's famous image, only older.
The original photograph was taken in 1984 in a refugee camp in northwest Pakistan during the Soviet occupation of Afghanistan.
Mr McCurry later tracked her down, after a 17-year search, to a remote Afghan village in 2002 where she was married to a baker, and the mother of three daughters.
