Hi, @yassine12 !
Thank you for sharing your question with our network.
It looks as though you may be updating your store’s policies and are hoping to input the correct business information.
Since your business would have been registered with your local tax authority, I recommend looking through any official business documents they would have provided. Depending upon your local jurisdiction and registration information, you may be able to gather this information in one spot. Regardless, this would be stored external to Shopify.
If you have not registered your business and are unsure if you need to, please do check with a business consultant familiar with your local laws and your business model. Shopify does not register businesses on their behalf and this would be your legal obligation.
Warm regards,
