We would like to remind account holders that electronic invoices sent by OTE, a.s., are now electronically sealed by qualified electronic seal certificates under European Parliament and Council Regulation No. 910/2014 on Electronic Identification and Confidence in Electronic Transactions and Act No. 297/2016 Coll., on Trust Services for Electronic Transactions. Certificates are issued by the PostSignum Qualified CA 2 certification authority. For proper seal validation, this authority must be stored in the list of trusted authorities.

At the same time, a time stamp from the PostSignum Qualified CA 3 authority is added to the electronic tax documents issued by OTE.

The public parts of electronic-seals have been published at this address: http://www.ote-cr.cz/registration-and-agreements/access-to-cs-ote/konfigurace-pc?set_language=en .
