Credit refused: debt enforcement register, ZEK, IKO and CRIF
Updated on 5 August 2026
In brief
Three separate systems can explain a refused credit or leasing application in Switzerland: the debt enforcement register kept by the offices; the ZEK, the database of credit and leasing institutions; and private credit-scoring agencies such as CRIF or Creditreform. Having an entry removed from the register therefore does not automatically clean the ZEK, and vice versa. The Data Protection Act gives you a right of access to your data (Art. 25 DSG) and a right to have inaccurate data corrected or deleted (Art. 32 DSG) with each organisation separately.
Many refused credit applications are wrongly blamed on a debt enforcement entry. In reality your bank or leasing company most often consults other databases, on which removing a register entry has no direct effect. Knowing who holds what is the precondition for correcting the right information in the right place.
Three databases not to be confused
The debt enforcement register is kept by the office at your place of residence; it records enforcement proceedings and is consulted via an extract costing CHF 17 (Art. 12a GebV SchKG). The ZEK (central office for credit information) is fed by banks, leasing companies and card issuers: it records credit applications, refusals and payment arrears. The IKO is the consumer credit register provided for by the Consumer Credit Act. Finally CRIF, Creditreform and Intrum are private companies that compute a creditworthiness score from a range of sources. A lender generally consults several of these.
Why removing an entry is not always enough
This is the classic unpleasant surprise: you obtain the withdrawal of an entry, your extract is clean — and the credit is still refused. The reason is that a ZEK record tied to a payment delay or an earlier refusal follows its own retention rules, independent of the debt enforcement register. Cleaning up your extract remains worthwhile, particularly with landlords and employers who consult only that register; but for credit, each database must be dealt with separately.
Exercising your right of access
The Federal Act on Data Protection lets you ask any organisation what data it holds about you (Art. 25 DSG); the request is in principle free of charge. Send it separately to the ZEK, the IKO and the relevant scoring agencies, enclosing a copy of an identity document. You will receive the individual records and their dates. This is the only way to learn what is actually blocking your file rather than guessing at it.
Having inaccurate data corrected
If a record is false, out of date, or rests on a contested debt, you can demand its correction or deletion (Art. 32 DSG). Send the organisation a reasoned written request enclosing the evidence: payment receipt, creditor's withdrawal confirmation, judgment. If it refuses, the organisation must at minimum note that the data is disputed. The Federal Data Protection and Information Commissioner can be approached if the exchange goes nowhere.
Can my bank see my debt enforcement entries?
Not directly: the register is not freely accessible. The bank can however require you to produce an extract yourself, and it consults the ZEK as well as credit-scoring agencies.
How long does a ZEK record stay?
Retention depends on the type of record and is set by the ZEK's own rules, independently of the five-year register deadline (Art. 8a para. 4 SchKG). Request access to your data to learn the exact date of each record.
Does a contested entry show up in my credit score?
It can, if the agency learned of the proceeding. An entry met with an objection that was never pursued is data you can challenge under Art. 32 DSG.
