Difference between Aadhaar and SSN
Aadhaar is a 12-digit unique identification number issued to Indian citizens by the Central government. It is issued and managed by Unique Identification Authority of India (UIDAI). The United States enacted the landmark Social Security Act in 1935, giving birth to the Social Security Number (SSN).
Aadhaar can be used as a single proof of identity and address for any resident in India. On the other hand SSN (Social Security Number) is used to track worker’s earnings and keep a record of social security benefits to be received by them. Temporary workers are also allowed to obtain SSN in certain cases.
Aadhaar project involves collection of biometric data which includes fingerprints, face and iris of eyes, whereas SSN captures demographic data.
