Mainland, free zone and financial free zone companies
UAE companies fall broadly into three groups. Mainland companies are licensed by an emirate's economic department and can trade across the UAE. Free zone companies are licensed by one of more than forty free zone authorities and are usually aimed at international trade or services. Financial free zones, the DIFC in Dubai and ADGM in Abu Dhabi, have their own common-law courts and financial regulators.
For banking, the licence type matters less than what the company actually does and where its substance is. Banks look for a real operating business in the UAE or a clear international business that is genuinely managed from there. A free zone company with a flexi-desk, no local staff and all customers abroad will face harder questions than a mainland trading company with a warehouse and local employees, but both can be banked with the right evidence.
