From 1 January 2026, registered electronic delivery (e-Doręczenia) replaced ePUAP as the primary channel Polish public authorities use to correspond with businesses and citizens that hold an e-Doręczenia address. Correspondence sent to an entity's e-Doręczenia address has the same legal effect as registered mail; relying only on the old ePUAP inbox after the cutover can be legally ineffective for parties obligated to hold an e-Doręczenia address.
Wer betroffen ist
All entities obligated to maintain an e-Doręczenia address, including businesses registered in the KRS or CEIDG within scope of the phased mandate, and public-trust professionals (advocates, tax advisers, notaries).

Was zu tun ist
Confirm your organisation's e-Doręczenia address is active and check it regularly, or set up email/SMS notifications, since statutory deadlines run from delivery to this address rather than from when you read it. Update internal processes so correspondence with public authorities defaults to e-Doręczenia instead of ePUAP or paper.
Applies to sole traders/businesses registered in CEIDG before 1 January 2025. Businesses registering in CEIDG from 1 January 2025 onward, and any pre-2025 CEIDG entrepreneur who filed a CEIDG update request after 30 June 2025, already had to set up an e-Doręczenia address earlier. Companies registered in the KRS had an earlier deadline: 1 April 2025 for those registered before 1 January 2025, and immediately at registration from 1 January 2025 for new KRS entities.
Sole traders (jednoosobowa działalność gospodarcza) and other CEIDG-registered businesses in Poland that registered before 1 January 2025 and have not already set up an e-Doręczenia address.
