It seems to me you are a sole proprietor.
I advise you to make your profile of sole proprietary, may be on letter head of your company signed by you. You can mention in the profile the details of your bankers, pan number and all other numbers allotted to you and your company. I feel this will suffice your purpose.
In other cases i.e. in partnership, LLP, Private or Public Limited company you can always take certificate from other Partner, Designated Partner, Director as the case may be.
