You must update your signature on SS Corporate's database if your signature has changed. The steps to accomplish so are as follows:

1. Fill out the account modification form and print it. Under details, put 'Change of signature,' specify the 'Type of change' as Modification, then sign using your old signature in the 'Existing details' section and your new signature in the 'New details' section. Also, sign your new signature inside the 'F' box.
2. Complete the KYC form. Use your new signature across the form, as well as across your connected photo.
3. Obtain a letter from your bank acknowledging your signature change. The banker's seal and signature, as well as your new signature, must be included in the letter. The format of a banker letter is shown below.
4. Send the above documents, as well as a photocopy of your PAN card and address proof, to the following address, both of which must be self-attested with your new signature.
5. The adjustment will cost you Rs.25 plus GST.
