You cannot delete digilocker account.
If your Aadhaar number is connected to Digilocker, then your Aadhaar number will be linked to your digilocker account permanently.
Also, you cannot delete the documents pulled from other departments (Income Tax Departments, CBSE etc.) in to digilocker account. However, you can delete all your uploaded documents from the digilocker.
