What are the rules for an Estonian OÜ name?
Last updated: Oct 21, 2026, 17:46 (UTC+08:00)
The name must show the legal form, OÜ or osaühing, at the beginning or end, and it must be clearly distinguishable from names already entered or booked in the Business Register. Check your options in the register's free name search first. We send the three names you give us through the same check.
