How to check a company name before formation
The free company-name check compares a proposed name with current names of active entities in the public register. It shows a text-similarity percentage and explains the main reason for every match.
- Enter the proposed name. You do not need to include a legal-form suffix.
- Review the closest matches. Focus on the percentage, pronunciation and the distinctive part of the name.
- Complete a manual review. Check trademarks and consult a notary about a borderline name before filing.
Company-name check FAQ
What does the text-similarity percentage mean?
The 0–100 percentage expresses character overlap after removing legal forms, accents, punctuation and common CZ/EU markers. It is not the probability that a court will register the name.
At what percentage does name similarity become risky?
For quick orientation, we highlight 90–100% as very high text similarity and 85–89% as a manual-review band. The overall impression, pronunciation and distinctive elements still matter.
Who decides whether a company name is accepted?
This tool provides only a preliminary check. Registration is decided by the registry court; a notary can review a borderline name before filing.
