That really depends on the offense, also you will need one of these. I think nobody really knows how related the document actually needs to be, to be considered valid
- Local business license
- Tax filing
- Invoice
- Certificate of Formation
- Articles of Incorporation
- Utility bill
- Proof of domain name registration
- Order fulfillment documentation
In general, I would say the least three will help you less, if at all.
IG might even reject every kind of document even if it matches the initial info on that account, It Really Do Be Like That Sometimes
