# BullionStar – Customer Information Update | Missing Proof of Address
Dear Valued Customer,
Thank you for being a valued customer of BullionStar! We appreciate your trust in us and are committed to providing you with the best service possible.
As part of our compliance with regulatory requirements, we need to conduct Customer Due Diligence (CDD) for certain customers, including you. This is a one-time procedure aimed at ensuring the security and integrity of your account. Rest assured, the documents you provide will be stored securely and confidentially, in accordance with the law.
To complete your CDD, we kindly ask you to upload a photo or scanned copy of a document that verifies your current address. You can easily do this by logging into your account at [BullionStar Account Details](https://www.bullionstar.com/myaccount/details) and selecting the 'Document Upload' option. Acceptable documents include a recent utility bill, bank statement, or any official correspondence that clearly displays your name and address.
If you prefer, you can also attach the document directly in a reply to this email. Please ensure that the document is clear and legible to avoid any delays in processing.
It is important to us that your customer information is complete and up-to-date. This not only helps us comply with regulations but also enhances the security of your account. We appreciate your understanding and cooperation in this matter.
Thank you for your prompt attention to this request. We look forward to your earliest response!
Yours sincerely,
The BullionStar Team
