Hello,
UIDAI has introduced Masked Aadhaar as an option while filling out the form in which the first 8 digits of your Aadhaar number will be replaced with "xxxx-xxxx," while only the last 4 digits will be visible. You must have selected that which is why you got this Aadhar. However, if you prefer to have an unmasked Aadhaar soft copy, you can download it from the UIDAI website and get it printed out.
Hope this helps,
Thank you
