Some online banks require proof of the company’s address. For a standard company, this normally means an office rental contract, or a utility bill.
As an e-Resident, with a virtual office, and traveling around the world, you cannot normally provide any of these documents. However, in this case, online banks understand that for companies created by e-Residents, the effective address of the business is the address where the company operates.
This place, which is normally outside of Estonia, corresponds to your current place of residence if you are the only member of the company, or where most of the activity is performed in the case of multiple-member companies. In that case, the easiest thing to do is presenting a rental contract of your current place of residence, or a water, electricity or telephone bill in your name, as director of the company.
