Admin online

The mailbox can be activated and used free of charge.

The easiest way to apply for a data mailbox activation is to visit a CzechPoint (= a platform for assisted access to the public administration system, learn more about it in our guide Authentication of copies and signatures, or see the map of CzechPoints / find the closest post office).

ou have to provide:

1. Your ID/passport
2. Your temporary/long-term/permanent residency permit or long-term visa. (If you don’t have either, read our guide on Residence Permits)
3. This application form, filled out. We prepared a PDF with English translation and instructions on how to fill in the form – open it here.

Once you provide all the documents above, you will get  ”Potvrzení o žádosti o zřízení datové schránky” = “confirmation of your request to create a Data Mailbox”, immediately on the spot in two copies. You have to sign them and give one back to the official at the CzechPoint. Please, review all the information carefully before signing the documents.

Business persons – including self-employed freelancers – must have Data Mailbox and the login is automatically sent to the freelancers after registering the business at the Trade Licensing office. It takes a couple of weeks though.

The access data will be sent by post to the contact address given by you in the application form in a few days.

You can set up your personal password and specify if the password has to be renewed every three months or can stay the same (less safe).

Delivery of correspondence via Data boxes is guaranteed. The owner of the Data Mailbox can be notified when he/she receives a new message. The owner can choose the preferred form of notification (SMS, email). A document delivered to a Data Mailbox is delivered at the moment at which a person authorised to access the delivered document logs into the Data Mailbox, otherwise the message is considered as received and read 10 days after being sent. Delivery of a document to a Data Mailbox has the same legal effect as delivery into the hands of the addressee.

Important: Make sure you set up the notification to your personal email or text message, because every document is considered as received and read 10 days after being sent (i.e. you can’t claim that you haven’t read it)

Sending correspondence and documents via the Data Mailbox is easy, it works basically like any other e-mail client. You open a new message, include a text or attach a document, insert the address of the institution (it has the form of several letters and numbers which have no meaning, e.g. Immigration office: 6bnaawp), and send the message. You can also see immediately a confirmation of delivery and later you can see a confirmation of the message being read. 

Most institutions have their Data Mailbox address stated in the Contacts section of their website; you can also search for the address directly via the interface. 

Important: once you set up a Data Mailbox, you are obliged to use it towards the Financial office, i.e. you cannot submit the paper version of your tax return anymore. 

Also, the messages in the online Data Mailbox are deleted after 90 days, unless you have a paid version which stores your messages. The “Data Safe” is free for the first 6 months and then you have to pay for it.

But, if you use the Datovka app, the messages are stored on your hard disc. 

The original online Data Mailbox version managed by the Czech Post is only in Czech.

However, you can download the application Datovka. 

Datovka is a cross-platform desktop application for accessing Data Mailboxes and permanently storing data messages on your local disc, similar to your e-mail client. The application has an English version, installation is only in Czech though. After installation and login, you have to go to Settings (cogwheel), select the last bookmark (jazyk) and switch the setting to English. After restarting, the app will function in English.

There are two types of online BrnoID: basic and full. For your basic ID, you just need to register with your e-mail. You can then:

• pay your waste collection fee,
• buy transferable tickets for Brno public transport, or even some the non-transferable ones for a short period of time,
• pay a fine if caught using public transport without a ticket,
• purchase the Brnopas tourist card,
• purchase zoo tickets,
• or tickets to some sports facilities (i.e. swimming pools in Kraví hora, Riviéra, Zábrdovice; or the ice rink Moravák).

For a full online ID, you need to get your personal data verified by uploading a scan of your identity card or visiting one of the verification places in person. Once verified, you can also

• manage resident parking and obtain parking permits (which are necessary to park in areas falling under the residential parking system)
• you’ll also be able to buy your long-term ‘šalinkarta‘.
• create a library account and manage it remotely.

For the basic functions, you can simply register with your email. The platform works like a standard e-shop.

For more advanced functions (such as buying your šalinkarta, the long-term tram/bus pass), you need to get your personal data verified by uploading a scan of your identity card or visiting one of the verification places in person.

Follow the instructions in the e-shop: the platform’s completely in English and free of charge to use.
