We inform users who register for the Electronic Invoice System via the Electronic Identification Portal - eID, that due to infrastructure work on the improvement of the eID Portal, the operation of the Electronic Identification Portal will be disrupted from Friday, April 17 to Sunday, April 19, 2026, and that there is a possibility that the Portal may be temporarily unavailable as a result.

 

The above works will not affect users who access SEF via the application programming interface (API).
