Datová schránka: how to set it up and use it

Updated: 15.07.2026

Datová schránka (a "data box") is the official electronic mailbox for communicating with the Czech state: authorities use it to send you decisions, and you use it to submit documents with full legal validity — no paperwork, no queues. Since 2023, data boxes have been created automatically for self-employed individuals (OSVČ) and legal entities; private individuals can also set one up voluntarily. Here's how it works and how to activate it.

What is a datová schránka

It's not email — it's a secure government communication channel. A message sent to your data box by an authority carries the same legal weight as a registered letter. Data boxes are commonly used to submit applications and to receive decisions from courts, the tax office (finanční úřad), social security bodies, and municipalities.

Who gets a data box automatically

Important deadline: activation within 15 days

Once a data box is created, there's a limited window for activation: if you don't log in yourself, it activates automatically once the set deadline passes (roughly 15 days). From that point on, delivery deadlines for messages start applying — so it's important to know your data box exists and to check it regularly.

"Delivery fiction" — why you can't ignore it

The key rule: a message is considered delivered on the 10th day after it's sent, even if you haven't opened it (tzv. fikce doručení). After that, deadlines for appeals and enforcement start running. The takeaway: check your data box regularly, or set up email notifications.

How to log in

You can log in using several electronic identification methods:

You can set up and access your data box on the mojedatovaschranka.cz portal, or in person at a Czech POINT desk (at a post office or municipal office).

How to set one up voluntarily (as a private individual)

  1. Prepare an identification method (Bank iD or Identita občana) — see also our upcoming guide on NIA ID / Bank iD.
  2. Submit an application online at chcidatovku.gov.cz or in person via Czech POINT.
  3. Get access, log in, and activate the mailbox within the given deadline.
  4. Set up email notifications so you don't miss any messages.
