Is your ADE address visible to everyone? Find out who can see your e-Delivery address - and why it is protected

On podpisano.pl we often hear the question:

„Is my e-Delivery address publicly visible?”

The answer is: it depends on who you are. An individual? A company? An office? In each case, the rules are different. But one thing is certain -. e-Delivery address (ADE) is personal data that is protected under the RODO. And today we explain exactly what that means.

What is ADE - and is it personal information?

ADE (electronic delivery address) is a unique electronic address assigned to a specific person, company or office. It allows you to receive official electronic letters - with the power of registered mail.

Although it doesn't look like a classic e-mail address, ADE meets the definition of personal data as defined by the GDPR, because:

  • is unambiguously linked to a specific person (or entity),

     

  • enables it identification In the e-Delivery system,

     

and its processing (e.g., by an authority) involves a duty of protection.

Why is ADE a personal data?

According to the RODO, personal data is any information that identifies an individual - directly or indirectly. ADE, as a unique identifier in the e-Delivery service, meets this condition.

Therefore e-Delivery system administrators must protect ADEs as much as name, PESEL or home address - Among other things, against unauthorized access, disclosure or processing.

Who can see your ADE?

Individual (citizen)
  • If you are an individual - your ADE is invisible to the public.
  • They only see it eligible public entities (e.g., offices, courts, Social Security), which must be able to serve you with a letter.
  • Companies, other individuals and organizations cannot search for your ADE - Even if they know your data.

Your ADE is not „email for publication” - it's your personal information and is protected accordingly.

Public entities (offices, schools, local government units JST)
  • The addresses of the ADE offices are public and open to the public - and very well.
  • This allows you to quickly send a letter to, for example, a municipality or county office - without printing and without visits to the post office.
Companies and organizations (CEIDG, KRS)
  • Companies, associations, foundations and other entities registered in CEIDG or KRS have obligation to have a public ADE.
  • Their addresses are listed in BAE for every citizen, government agency, and business.
Deadlines
  • KRS - mandatory as of April 1, 2025
  • CEIDG - for each change of entry from July 1, 2025, for all no later than October 1, 2026

What about RODO protection?

ADE administrator's responsibility

The administrator of the e-Delivery box (i.e. the person who sets it up and manages it) has a obligation to protect users' personal data, including ADE. This includes, among others:

  • Restricting access to data to authorized persons only,

     

  • Ensuring the security of the systems in which the data is processed,

     

  • Enabling the exercise of users' rights (e.g., access to data, rectification, deletion - in cases provided for by law).

What are the implications of this?

Your private e-Delivery address is safe and hidden from the outside world, but visible to authorities, who have the right to contact you electronically.

On the other hand, if you run a business or are an official -. Your ADE will be public. But rest assured - it's not a phone number or email. It's a legal communication tool that is used for official deliveries only.
