How many e-Delivery boxes can a company, citizen, office have? Guide with examples
15-minute read Updated: August 18, 2026

Can you have more than one e-Delivery box?

Bottom line: As a rule One person or company = one e-Delivery address, but there are exceptions to every rule. Below we explain the details for different situations: individuals, businesses, offices and attorneys. We will answer the question of when having several boxes makes sense and what limitations the law imposes.

Individuals and entrepreneurs - when can you have two addresses?

For an ordinary citizen who does not run a company, the matter is simple: he is entitled to one e-Delivery box (electronic delivery address). The law introduced the principle that in the state database of electronic addresses (BAE) one entity can have only one address. This means that we can't have several boxes - the state wants to avoid chaos.

Exception: However, if the same person acts in different roles, such as running a business or practicing a profession of public trust (lawyer, legal counsel, notary, etc.), then there is a different situation. In such cases, the person should  Have two e-Delivery addresses - one for private purposes and the other for professional purposes. The law explicitly provides for this for entrepreneurs enrolled in CEIDG and, among others, attorneys, legal advisors, tax advisors and other similar professions. As a result, a lawyer, for example, should have a separate box for contacting the court as a professional attorney, regardless of the private box used for personal correspondence.

From the user's point of view, this is good news - you can separate business and private affairs. For example, entrepreneur Jan Kowalski may have an e-Delivery address „Jan Kowalski - Company” for the company's official contacts and a separate address „Jan Kowalski - Private” for non-business related correspondence. Both mailboxes are assigned to the same person, but to different roles, which is in accordance with the regulations.

Companies - each company is a separate entity and a separate box

Companies and business activities also applies the principle of „one entity = one address.” Every entrepreneur (be it a sole proprietorship or a company) should have their own electronic delivery address entered in the database. It is not possible for one company to set up two or three e-Delivery boxes for itself - this would contradict the idea of a unique official address for an entity. If by some miracle two addresses were created for the same company, the relevant Minister of Digitization would act as an order controller and cancel the redundant address. In other words, duplication of company mailboxes is out of the question (such a „redundant” address will be removed from the register).

What about the situation when one person has several companies? Here we distinguish between two scenarios:

  • One-person business: In Poland, one individual can only have one JDG (entry in CEIDG) and one number NIP - even if he conducts many different activities, it all falls under one enterprise. Therefore, such a person sets up one e-Delivery address for his business. Even if you provide different services under the JDG banner (e.g., you run a kiosk and a garage at the same time as one business), you use the one corporate e-Delivery address. However, you have the right to a second address as an individual, unrelated to the company, as mentioned above.

  • Many companies or entities: If you run or are a partner in several separate companies (e.g., limited liability company X, limited liability company Y), then each company must have a separate address for service. In practice, you as the owner/shareholder will be associated with several boxes - one for each company. This is not only allowed, but even required, because each company is a separate legal entity. On the other hand, it is not possible for one company to set up several addresses for itself - one must suffice.

The good news: Just because a company has a single e-Delivery address does not at all mean that the CEO or owner has to personally receive every message. The solutions offered by Asseco - available through podpisano.pl - allow convenient management of the mailbox by multiple users simultaneously. Already at the application stage you can specify several administrators who will have access to the same company mailbox. This could be, for example, an administrative employee, an accountant or even an external accounting office.

As a result, the responsibilities for receiving and sending correspondence can be flexibly divided, without the risk of overlooking important letters. This is a real convenience - especially in larger organizations where more than one person must have access to the mailbox. These solutions allow for efficient, secure and compliant teamwork in e-Delivery.

Public offices and institutions - one office, one address... with exceptions

In the case of public entities (offices, state and local government institutions, etc.) also have a rule of one address per entity. Each institution has its own official e-delivery address, which it must set up and disclose in the database of electronic addresses. For example, a municipal office, a county labor office or a public school - each of them has its own e-Delivery box, which becomes the default channel for receiving official correspondence.

Can an office have several boxes? As a rule, no, but here, too, the legislature has provided some flexibility for elaborate structures. If the institution has branches or subsidiaries in the field, which operate fairly independently, then it can request additional addresses -. one for each branch. This requires the approval of the Minister of Information Technology, but is feasible. It is important that such a branch actually performs separate tasks at its location and makes sense to have its own box. For example, a large city office with many field departments could get separate e-Delivery addresses for branches, e.g. the communications branch in district X, the civil affairs branch in district Y, etc., instead of handling everything through the headquarters.

Even if the office has several addresses for branches, must indicate one main address (central) as the primary one. Each branch applies for an address separately and receives its own unique identifier, entered into the database. Such a division streamlines correspondence - letters concerning local matters can go straight to the local branch, instead of circulating through the headquarters.

Thus, in practice, a public institution does not create multiple „spare” boxes”, but can have one per organizational unit. When there have been cases of setting up two addresses for the same office (e.g., for a municipality and in parallel for a municipal office as a separately notified entity), the regulations mandate the deletion of the redundant address, so that only one proper one remains. Order must be - each office has a clearly defined official address for service.

Law firms and attorneys - one ADE, many clients

Law firms, accounting offices and other attorneys They often deal with multiple clients. Does that mean they can set up ten e-Delivery boxes for themselves - one for each client? No. Formally, each box is assigned to a specific entity (person or company). The law firm as a business will have your own single address e-Delivery (e.g., „XYZ law firm - delivery”), just like any other business. It cannot have separate official addresses for individual clients, because clients are not branches of the law firm - they are separate entities.

So how will an attorney receive letters for a client via e-Delivery? Well, in official and court communications, the rule is that if an attorney for service has been appointed, then correspondence may be addressed to the address of that attorney. In the digital world, this means that, for example, a court or office will send a letter directly to the e-Delivery box of the lawyer/counsel representing the client, instead of to the client's address. Yes, you read correctly - a lawyer can get an official letter for a client at the your own e-address. The aforementioned provision mentions that a person acting as a professional attorney should use a separate address for professional matters. Therefore, an attorney uses the address of his law office (or personal professional address) to handle client matters, which separates these matters from his private correspondence.

For an accounting firm or tax advisor, it looks similar: any official letter can go to the advisor's e-Delivery address, if he or she has been formally appointed as an attorney to receive the firm's correspondence. Of course, each represented customer must have its own entry in the address database - most often it will simply be the address of that company, to which the proxy has access or redirection. Thus, the accounting office can help many entrepreneurs, but by logging into their mailboxes one by one (as an administrator or authorized user). The system makes it possible to give access to the e-Advice mailbox to another person, such as just an accountant or lawyer, both permanently and as a replacement during an absence. This allows the attorney to manage the correspondence of various entities, But they are still separate boxes for each entity, not one magic box for everything.

In practice, lawyers often combine several roles and addresses. Example: a legal advisor employed as a full-time employee in an office at the same time runs his own law firm. Such a counselor will have Two separate e-Delivery addresses - one official office he will use for official correspondence, and the other is the address of his private business (law firm). When communicating, he can use either the address of the office (when acting as an employee of the office) or the address of his law firm (when acting as an independent attorney). Similarly, if a lawyer is a partner in a law firm registered in KRS, the firm has its own address for service, independent of the lawyer's own address. Everything is separated so that it is clear „who is who” in a given case and at which address he receives letters.

Formal and technical limitations - why does it work that way?

Law imposes restrictions, to keep digital correspondence in order. If everyone could set up as many official mailboxes as they wanted, offices wouldn't know which address was right for which citizen or company. That's why The electronic delivery law adopts the principle of one address per subject. The exceptions have been clearly indicated (two boxes for people combining private and professional roles) and do not depend on the discretion of officials - they follow directly from the regulations.

From the technical The e-Delivery system makes sure not to duplicate entries. Attempting to set up a second address for the same PESEL or NIP will end in the rejection of the application (or its subsequent cancellation). The Ministry of Digitization even has the power to strike an additional address from the official registry if it has somehow been registered against the rules. In other words -. one box is your official address and that's it. Want to change your address? You can update your mailbox data, but you won't set up a second one „just in case.”.

It is also worth remembering that each e-Delivery address must be associated with a trusted service - either a public service of registered electronic delivery (PURDE) offered by a designated operator (Poczta Polska), or with a qualified delivery service from a private provider. We won't set up a box without using such a service, so in terms of infrastructure, too, it doesn't make sense to multiply accounts beyond the need. For that multiple users can be hooked up to one box (e.g., several clerks handling one office box, or several employees in a company) - this is provided for and facilitates cooperation.

When is it a good idea to have more than one eDelivery address?

Given these principles, in what situations having several addresses (under permitted scenarios) is practical and reasonable? Here are some examples:

  • Separation of private and business life: If you are running a business, a separate e-Delivery address for your company will allow you to separate official business letters from personal correspondence. You will avoid clutter and the risk that an important letter from Social Security or the tax office will get lost among private messages. In addition, when you are done with work, you can log out from the company's mailbox and have peace of mind - something that in the era of #homeoffice can sometimes be salutary 😉.
  • Separate addresses for different companies or branches: If you have several companies, each entity has its own legal identity - and its own mailbox. This makes it easier to manage, because correspondence regarding company A doesn't get mixed up with that of company B. In case of an inspection or audit, you have order: each company communicates with the authorities at its own unique address. Also large institutions with branches use multiple mailboxes to speed up the handling of local issues - The letter goes straight to the relevant department, instead of circulating internally.
  • A law firm serving multiple entities - For lawyers and advisors, it is not possible to have a separate e-Delivery inbox assigned to each client—however, the new technical solution will make it possible to keep a single shared inbox organized ADE, by organizing correspondence by client and case, which will improve transparency, security, and control. It’s like a separate „drawer” dedicated solely to a single client’s cases—an authorized representative (e.g., you or a designated person) will have access to this „drawer” based on authorization or as an administrator. This way, different cases won’t get “mixed up.” Imagine a situation where, in one „big bag,” it would be very easy to miss a deadline or send a letter to the wrong person. Separate „drawers” effectively eliminate this risk. The Asseco e-Delivery System (accessible via podpisano.pl) supports this type of workflow organization. When setting up a mailbox—coming soon—you’ll be able to designate several administrators whom you authorize to receive and send messages—each „compartment” will be isolated and accessible only to the assigned team. This model prevents correspondence chaos while allowing you to operate efficiently and professionally. Importantly, this feature will be available in the Asseco offering in the third quarter of 2025.

  • Different professional roles of one person: Sometimes one person wears several hats - for example, he or she is simultaneously a civil servant, an entrepreneur and, let's say, still an after-hours real estate appraiser. Having a separate address for each role, such a person will keep correspondence in order. When he acts as an official - he uses the address of the institution. When he writes back as a company owner - he uses the company's mailbox. And he receives private letters at his personal address. In this way, he avoids a situation where he has, for example, a decision from the office for himself as a citizen mixed up with letters relating to the business of the company in one box. It's as if the letter carrier delivered your home letters and all the mail for your company to one box at the same time - it would quickly get paper mess (and yet we want #paperless!).

In summary, the e-Consultation system is designed to. assign each entity a unique official address. This makes it clear where to direct official letters electronically. The multiplication of addresses is limited on purpose - it is to ensure transparency and security of delivery. If you have multiple roles, the law gives you the option of several boxes, but it is always one address on one specific identity or function. This can be compared to PESEL/NIP numbers - you also have one main one, although you can conduct different activities. For that, you can organize teamwork (adding authorized persons) within one e-Delivery address and integrate this channel into the workflow of the company or office.

Finally, it's worth adding a bit of optimism: although it may seem complicated at first, e-Delivery is supposed to make our lives easier, reduce running to the post office and piles of paper. One box per head (or per company) is a tidbit - and it's a tidy one. Everything under control, with proof of delivery and electronic signature. And that sometimes we have more of these boxes (because we also wear several hats) - well, a sign of the times and the digital revolution.
