Digital stamp

Digitempli teenuse piltDigital stamp that is used for certifying digital documents proves that electronically sent documents or other information really originates from the institution that sent them. A digital stamp certifies that the respective institution is associated with the specific document and the document has not been altered in the meantime.

The digital stamp can be used by enterprises, state and local authorities, self-employed persons and holders of a public office.

The digital stamp can be used along with a digital signature as well as without it. Using a digital stamp certificate along with the person’s digital signature you can be certain that the person who signed the document is authorised to sign documents on behalf of the respective enterprise.

Banks issue payment order confirmations that certify payments being made and are equipped with the digital stamp. The digital stamp is also used in real property valuation reports, in powers of attorney sent to the Estonian Motor Vehicle Registration Centre by leasing companies and in certificates issued by the National Examination and Qualifications Centre.
