Business partner check by IČO (Czech company ID)
Enter the IČO and within a second you will see whether the company is active, whether it is in insolvency, whether it is listed as an unreliable VAT payer and which account you may safely pay it into. Data from four public registers in one place.
How do I check a business partner by IČO?
Enter the IČO in the form above — the tool queries the register of economic entities (ARES), the commercial register, the register of DPH (Czech VAT) payers and the ISIR insolvency register at the same time and sums the result up into a single assessment. You will find out whether the company exists and is active, who is authorised to act for it, whether insolvency proceedings are under way against it, whether it is listed as an unreliable VAT payer and which bank accounts it has published. That last point matters: if you pay a VAT payer into an account that is not on the list, you may become liable for the tax it fails to remit.
Before you sign a contract, send a deposit or start supplying on invoice, it pays to check the other side. The information is public, but scattered across four state registers. This tool asks all of them at once and sums them up into a single, readable assessment — free of charge and with no registration.
- 1Enter your partner's eight-digit IČO (if your number is shorter, we add the leading zeros for you).
- 2The tool queries four public registers at the same time.
- 3You see an overall assessment and, beneath it, a breakdown by individual source.
What each signal means
| Signal | Risk | What to do |
|---|---|---|
| Insolvency proceedings | High | Do not supply on invoice, arrange payment in advance |
| Unreliable VAT payer | High | You are liable for the tax it fails to pay — consider remitting the VAT to the tax office directly |
| Inactive entity | High | The company has been wound up or is in liquidation — establish who the successor is |
| VAT payer with no published account | Medium | Pay only into an account from the register, otherwise you risk liability for the tax |
| No warning signals | Low | Standard caution; for larger volumes consider receivables insurance |
The overview is intended for orientation. It is not a credit rating — that is assessed by specialised services and insurers.
Insolvency or an entity being wound up is a reason to ask for payment in advance — and you find out before you ship the goods.
With an unreliable VAT payer, and when paying into an account that has not been published, you may become liable for the tax it fails to remit. The tool shows both.
You see who is authorised to act for the company, together with the exact details for the contract header.
