Voice Call Compliance in Czechia
A practical overview of the rules that affect voice call messaging and marketing in Czechia, with a checklist before you launch.
Key Rules for Voice Calls in Czechia
Since 2022, marketing calls to individuals in Czechia require prior consent under the Electronic Communications Act, and the GDPR also applies.
European countries regulate marketing calls through national laws and do-not-call or objection registers, and automated (recorded) marketing calls generally require prior consent.
Data Protection
The Office for Personal Data Protection (ÚOOÚ) enforces the GDPR, and consent is required before non-essential cookies.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Check whether the call is promotional or a service call, as the rules differ.
- Use permitted calling numbers and caller ID, and never hide or spoof the calling number.
- Screen numbers against any national do-not-call register before promotional campaigns.
- Call only within permitted hours in the recipient's time zone and keep recorded messages short.
- Offer an easy way to stop further calls and record call consent where required.
Contact data
Format numbers in international E.164 format with the +420 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Czechia follows the Europe/Prague time zone (UTC+02:00 in October 2026). The usual working week is Monday to Friday. Schedule voice call campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Prague, customers commonly use Czech, with English. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Czechia
Czechia has high smartphone use, and Messenger and WhatsApp are popular, while SMS remains common for transactional messages. Because the local search engine Seznam.cz and its email service are still widely used, digital campaigns often run on Seznam's advertising platform (Sklik) alongside Google.
Card and contactless payments are very common, and QR-code bank transfers are standard for invoices. Christmas markets, Easter and Black Friday are key moments, and Czech-language content is expected for consumers.
The Czech Republic is one of the most industrialised economies in Europe: Škoda Auto in Mladá Boleslav, Hyundai at Nošovice and Toyota in Kolín make cars, and machinery, electronics and engineering exports go mainly to Germany. Unemployment has been among the lowest in the EU. VAT is 21%, and the currency is the koruna rather than the euro. Act 480/2004 on information society services requires prior consent for commercial messages by email and SMS, overseen by the data protection office (ÚOOÚ). O2, T-Mobile and Vodafone operate the mobile networks.
Regulators, Registers and Practical Rules in Czechia
Czechia's Act 480/2004 requires prior consent for electronic marketing, and ÚOOÚ enforces the GDPR.
The Czech Telecommunication Office regulates telecoms. Messages should be in Czech.
The Czech Data Protection Office (ÚOOÚ) also enforces the anti-spam rules in Act 480/2004 on certain information society services, which requires prior consent for commercial communications by email and SMS, except for similar products sold to existing customers. O2, T-Mobile and Vodafone are the operators. WhatsApp and Messenger are both widely used.
