Why do you need a separate electronic box
e-Doręczenia is a service of legally meaningful delivery, rather than an ordinary email. The ADE address is entered in the Database of Electronic Addresses. For a private person, the connection is generally voluntary, but a specific online service may require this channel. The rules for an entrepreneur or a professional representative are different.
As of 1 January 2026, e-Doręczenia is the main channel for such correspondence, unless a special procedure provides for another. The old common ePUAP form cannot be automatically considered as a substitute for any formal submission. For example, the application for residence, for which the MOS is intended, should be sent through the MOS and not simply as an attachment to a letter.
Open the address and activate it
Start from the official section gov.pl/e-doreczenia, go to the service to create an address for a private person and log in through login.gov.pl. You will need an accessible means of identity verification, such as Profil zaufany. Provide real details and contact for notifications; before sending, make sure that you are creating a personal address, not an organizational address.
After a positive result of the request, perform the activation specified in the service. Then go to edoreczenia.gov.pl and make sure that the box is available. One submitted application does not mean that you are already able to receive and send emails. If the login does not work, do not wait until the last day of the deadline: use the alternative channel available in your procedure.

How to send a letter to the agency
Find the recipient in the BAE search within the service. Check the full name of the body, not just the city. In the subject line, specify the case number and the action, e.g. adding documents. Prepare a signed application and the necessary attachments: the delivery service does not cancel the requirement to sign the application itself.
After sending the email, download the available proofs of sending and receiving. Also keep the exact version of the attachments. The "Send" button screenshot is weaker than the system proof; it is difficult to determine what was sent and when. If the recipient is wrong, do not expect the notification in the app to automatically correct the recipient.
Incoming should be checked regularly
A message from a public authority may be deemed to have been delivered after the statutory deadline, even if you have not opened it; the official FAQ warns about the 14-day mechanism. Rely on the system proof of delivery and instruction, not on the day when noticed the email notification.
Choose a constant time to check your inbox and check the spam folder in the notification email. The external notification is only a signal; the document itself should be read in the official box. If there is a representative, agree in advance who will follow up on the letters and where the correspondence is sent.

Do not send your passport via a suspicious link
Open the service from a bookmarked official domain. Do not enter the bank code or password Profil zaufany on the page from a random SMS. If the notification is doubtful, log in to the box separately and find the message there. For correspondence with agencies, the public service is free; paid commercial "activation of the address" is not a mandatory step.
