Company details required on a Czech website and e-shop

A Czech company website must show the business’s name (trade name) and registered office; we always recommend the company ID (IČO). An e-shop selling to consumers also provides, before the order, terms and conditions, complaints information, withdrawal instructions (14 days) with a model form and information on out-of-court dispute resolution at the ČOI, and from 1 January 2027 a withdrawal button. WebMeter looks for these details for free and verifies the IČO in ARES. It is not a legal assessment.

Which details belong on a Czech company website and e-shop

Under Section 435 of the Czech Civil Code, a business states its name (trade name) and registered office on business documents and in information made available remotely, which includes its website. On business documents it adds its entry in the public register, for the Commercial Register including the section and file number, and its company ID.
The IČO is the Czech company identification number. Anyone can use it to look the company up in ARES, a public Ministry of Finance system that combines data from the commercial, trade and other registers.
An e-shop selling to consumers must provide information under the Czech Civil Code and the Consumer Protection Act before an order, including a statement that disputes can be resolved out of court at the Czech Trade Inspection Authority (ČOI). The table gives an overview.
From 1 January 2027, e-shops must also offer a withdrawal button (Section 1830a of the Czech Civil Code, Act No. 159/2026 Coll.). How the button should work.

Withdrawal button for Czech e-shops from 1 January 2027

From 1 January 2027, an e-shop that concludes contracts with consumers online must let them withdraw from the contract with a button directly in its interface (Section 1830a of the Czech Civil Code, Act No. 159/2026 Coll.). The Czech rule is based on Directive (EU) 2023/2673, which amended the Consumer Rights Directive. The button is an additional way to withdraw; other ways, such as e-mail or the model form, remain.

Under the directive, the function should work roughly like this:

A clearly labelled button is prominently displayed and available throughout the withdrawal period.
The customer enters or confirms who they are, which contract they are withdrawing from (for example by order number) and where to send the confirmation.
They submit the withdrawal with a second, confirmation button, again clearly labelled.
The e-shop acknowledges receipt without undue delay, typically by e-mail, including the content of the withdrawal and the date and time it was sent.

The terms and conditions should say where customers find the button. Check the labels and design for your e-shop with your e-shop provider and your lawyer.

WebMeter looks for a mention of the button in the terms and conditions. Until the end of 2026 it reports a missing mention only as information, from 1 January 2027 as a finding. It doesn’t test the function itself: it doesn’t place orders, fill in forms or log in to customer accounts. Check your e-shop for free.

Why company details matter for a small business

Complete operator details are the first thing customers use to judge whether to trust an e-shop. The ČOI keeps a public list of risky e-shops, and one reason for being listed is that a website doesn’t say who operates it. Under the Czech Consumer Protection Act, missing complaints information can result in a fine of up to three million CZK, and missing information on out-of-court dispute resolution up to one million CZK. If an e-shop doesn’t inform consumers of their right to withdraw, the withdrawal period is extended by one year. Unclear or incomplete terms also cause disputes with customers that cost time and money.

Common problems with company details

The IČO and registered office appear only in terms and conditions in PDF format, not on the website itself.
An IČO with a typo, or the IČO of a company that has since ceased to exist.
Terms and conditions copied from another website, without withdrawal instructions or without the 14-day period.
The model withdrawal form or the paragraph on out-of-court dispute resolution at the ČOI is missing.
The terms still link to the EU online dispute resolution (ODR) platform, which the EU discontinued on 20 July 2025.
Contact only through a form, with no e-mail address or phone number.

E-shop legal requirements: what we check

This area is based on Czech law, so it applies to websites on a .cz domain or in Czech. WebMeter looks for the IČO on the homepage, in the terms and conditions and on one page such as Contact or About us. It checks its check digit and looks up one IČO in ARES: whether the company exists and whether it has ceased to exist. The report shows the name, registered office and VAT number from the register. WebMeter also compares the IČO and VAT number in the structured data about the company with ARES, and checks whether the website gives an e-mail address and phone number that can be opened or dialled with one tap.

If the website looks like an e-shop (a basket, an add-to-basket button, a known platform, product data), it looks for the links and parts of the terms listed in the table above, including accessibility information. On one product page it checks that the structured data for Google include a price and currency. For an e-shop that, according to its text, sells only to businesses, findings on consumer rights are informational only. On any website it assesses, it also flags links to the discontinued ODR platform. The cookie banner and tracking before consent are covered by the Cookies and GDPR area.

WebMeter reads at most six pages in addition to the homepage and doesn’t open PDF content. It searches by keywords, so it doesn’t assess whether the terms are complete, correct or valid. It reports “not found” only for pages it actually read. The result is not a legal assessment and doesn’t claim that the website complies with the law. For now, the area is informational and doesn’t count towards the overall score. How we measure is described in the methodology.

Website design with company details in the right place

On a new company website or e-shop, the name, registered office, company ID (IČO) and contact details sit on the pages themselves, not only in a PDF. Links to the terms and conditions, complaints procedure and withdrawal information get a fixed place. The wording of the terms is for your lawyer to review.

FAQ on company details and e-shops

What must a Czech e-shop include?

An e-shop selling to consumers shows its name (trade name) and registered office and, before the order, provides terms and conditions, complaints information, withdrawal instructions (14 days) with a model form and information on out-of-court dispute resolution at the ČOI. From 1 January 2027 a withdrawal button is added. We always recommend the IČO, contact details and a link to the privacy policy. WebMeter looks for these parts for free but doesn’t assess whether they are correct.

Does the IČO have to be on the website?

For websites, Section 435 of the Czech Civil Code explicitly names the business’s name and registered office; it ties the IČO and the register entry to business documents. But the IČO is what customers use to verify the company in the register. That’s why WebMeter reports a missing IČO, and treats it as a more serious finding for an e-shop.

From when must a Czech e-shop have a withdrawal button?

From 1 January 2027, under Section 1830a of the Czech Civil Code (Act No. 159/2026 Coll.). It applies to contracts with consumers concluded online. The button should be clearly visible throughout the withdrawal period, and the terms should say where customers find it. WebMeter only looks for the mention in the terms; it doesn’t test the function.

Does WebMeter assess whether the terms and conditions are in order?

No. It only checks whether it finds the terms and whether they contain key parts: withdrawal instructions with the 14-day period, a model form, complaints and out-of-court dispute resolution. Whether the terms are complete and fit your business can only be judged by a lawyer.

Why doesn’t this area apply to my website outside the Czech Republic?

The check is based on Czech law and on the Czech ARES register. WebMeter therefore doesn’t assess this area for a website without a “.cz” domain and without Czech on the homepage. The exception is a website with Czech text whose IČO ARES lists as active.
