Electronic PDF registration certificates are available for free from the Estonian e-Business Register.
This is what a machine translated registration certificate looks like in English.
To obtain your free registration certificate visit e-Business Register and search for your company name or registry code.
In the company view click on registry card icon. Then click on PDF icon in the right top corner to download.
The registry card is machine translated and may accidentally contain information in Estonian too. To order an official translation, please contact a sworn translator. Details of sworn translators are here.
For certified paper documents you should contact one of the notaries in Estonia. Estonian Business Register does not issue certified paper documents.
Estonian notaries are also responsible for issuing an apostille to certify the Estonian public records for use in other foreign jurisdictions.
