Rubber stamps for member in practice

These three Stamps are enough.

1. Round Seal - It will contain name of the firm, Address.

2. For Seal  - It will contain signatory details like - For Firm Name - Partner/proprietor 

3. FRN Seal - It will contain the Firm Registration Number.

I think the FRN number can be incorporated in the Round Seal, but not sure.

Thanks!!! What about the membership no. stamp? This is the one which members use for attestation among other purposes. Should it be rectangular or circular or either ways?

Please confirm. I just wanted to confirm that there is no mandatory standard format for the membership no. rubber stamp.

My name is very lengthy . can i make my name short on the rubber stamp.

short name as K.Venugopalrao

can practicing company secretary start part time work without registering the firm and signing in his name with membership no and CP no. under the stamp?
