Selection and verification of the business name


The selection of business name is one of the most important steps in establishing a company. A distinctive and memorable business name will contribute to the renown and success of a firm.

Restrictions on business names

The following restrictions have been set for choosing a business name in Estonia:

  • the business name must contain a reference to the legal form of the company (for example, ‘OÜ’ or ‘osaühing’ (private limited company) at the beginning or end of the name);
  • the business name of a sole proprietor must include the first and last name of the proprietor;
  • the business name may not contain the name of a person who is not a partner in a general partnership, who is not a partner in a limited partnership, or who is not a sole proprietor;
  • the business name must be clearly distinguishable from other business names entered and booked in the business register in Estonia;
  • a verbal, letter, or numerical sign protected as a trade mark in Estonia may not be used in the business name without the notarised consent of the owner of the trade mark, unless the entrepreneur operates in a field of activity for which the trade mark is not protected;
  • the business name and field of activity must not conflict with each other;
  • names of state or local government bodies and agencies may not be used in the business name;
  • the business name of a branch of a foreign company must consist of the business name of the company and the words ‘Eesti filiaal’ (Estonian branch).

Clear distinguishability of business name

The requirement that a business name be clearly distinguishable is not limited by the specific number of letters or syllables that must be different. In some cases, merely one letter is sufficient to be different, while in another case, even three letters will not be enough. It is not just the appearance of the word that must be different but the pronunciation as well. Nor are differences in declensions, conjugations and other grammatical word endings considered differences.

A company’s business name may not be too short and should also reflect the company’s main activity (such as goods produced, services) and location of the company or shareholders/founders.

Verification of business name

You can verify the distinctiveness of you preferred business name. You can do so in the name query section of the e-Business Register information system, where the new name is compared to those already entered in the register. The court maintaining the register makes a decision regarding the distinctiveness and suitability of the business name.

You can query the trademark database on the Patent Office’s website. The decision on the distinctive character and suitability of a business name shall be taken by the registrar of the commercial register.
