No, you’ll need your mobile number linked to your Aadhaar to complete the online account opening process with ArihantPlus. 

Alternative options: 

Option 1: Link your mobile number to Aadhaar 
 Visit your nearest Aadhaar Seva Kendra to link your mobile number. You can find the closest center on uidai.gov.in. Once linked, you can easily open your ArihantPlus account online. 

Option 2: Open your account offline 
 If your Aadhaar isn’t linked to your mobile number, you can still open your ArihantPlus account offline — no Aadhaar-mobile link needed.
