New Delhi, Nov 2 (PTI): The UIDAI, which issues national identity cards to citizens, today said it generated two crore Aadhaar numbers in the month of October.

"In another major milestone, the Unique Identification Development Authority of India (UIDAI) has generated two crore Aadhaar numbers in the month of October, 2011, alone," an official statement said.

The UIDAI launched the Aadhaar scheme in September last year and the authority was to issue 200 million national identity cards bearing unique numbers by end-March, 2012.

"While in 2010, it took three months to cross the one million-mark, we have the capability to generate that many Aadhaar cards in a day now. We would work on stabilising and consolidating this capability in the coming days. We have been able to achieve this speed and scale due to our multiple registrar model, as well as scalable technical architecture," UIDAI Chairman Nandan Nilekani said.

At present, there are around 20,000 enrollment stations across the country being run by about 50 registrars for registration of citizens under the scheme.

The UIDAI has generated 59.6 million crore Aadhaar numbers in a short span of a little more than a year and more than 100 million citizens have enrolled themselves in the system across the country, the statement said.
