ZEK Codes Switzerland - meaning for loans and credit opportunities explained

Anyone wishing to apply for a loan in Switzerland will almost always be confronted with the ZEK - Central Office for Credit Information confronted. Banks use this database to check the creditworthiness of borrowers. Information on loans, leasing contracts, credit cards and credit enquiries is stored in the ZEK.

A particularly important component of this database are the so-called ZEK Codes. These codes show banks how a borrower has behaved in the past. They indicate whether loans have been repaid correctly or whether there have been payment problems.

The ZEK codes are therefore a key factor in the decision to apply for a loan. If you want to understand your own entries, you can use a Free self-disclosure at the ZEK request.

This self-disclosure shows which codes and entries are stored about a person.

ZEK entry and credit in Switzerland explained


What are ZEK codes?

ZEK codes are Creditworthiness indicatorsreported by banks and financial institutions to the Central Office for Credit Information. They describe certain events in connection with loans, leasing contracts or credit cards.

In contrast to a traditional credit score, ZEK codes do not represent a score. Instead, they provide concrete indications of a borrower's behaviour, for example:

  • Correctly repaid loans
  • late payments
  • Canceled loan agreements
  • Losses for lenders

Banks use this information to assess the risk of a loan application.


Overview of all important ZEK codes in Switzerland

Table: ZEK codes and meaning

ZEK CodeMeaningInfluence on credit
00No negative entry availableVery positive
01Loan repaid in fullPositive
02Current loan serviced correctlyneutral to positive
03late paymentsnegative

05Loss for lendersVery strongly negative
21Credit card blocked due to late paymentnegative
22Debt collection by credit card providersstrongly negative

These codes give banks an indication of how reliably a borrower has fulfilled their obligations.


Meaning of the individual ZEK codes

ZEK Code 00 - no negative entry

The code 00 shows that no negative information about a person is stored. This is a good sign for banks, as there are no indications of payment problems.

Borrowers with code 00 generally have a good chance of being approved for a loan.


ZEK Code 01 - Credit successfully completed

This code means that a loan has been repaid in full. Banks often interpret this entry positively, as it shows that a borrower has already serviced a loan correctly once.


ZEK Code 02 - current loan without problems

Code 02 indicates that a loan is currently still running but is being repaid correctly. Such an entry is not normally a problem for banks.

However, lenders also check whether the financial burden still leaves sufficient scope for a further loan.


ZEK Code 03 - late payments

This code shows that there have been late payments in the past. Banks see this as an initial warning signal.

A loan may still be possible, but it depends heavily on your current financial situation.


ZEK Code 04 - Loan agreement cancelled

Code 04 is one of the more problematic entries. It means that a credit agreement has been cancelled due to payment problems.

Many banks automatically reject loan applications with this entry.

ZEK Code 05 - Loss for lender

This code shows that a bank has suffered a financial loss. This is one of the most serious entries in the ZEK.

Loans are usually very difficult to obtain in such cases.


ZEK Code 21 - Credit card blocked

This code is used when a credit card has been blocked or cancelled due to payment problems.

Even if it is not directly related to a loan, this entry can have a negative impact on your credit rating.


ZEK Code 22 - Debt collection by credit card provider

Code 22 indicates that a credit card provider has initiated debt collection proceedings.

This is a very negative signal for banks.


ZEK Code 23 - Loss from credit card receivables

This code shows that a credit card provider has suffered a financial loss. Similar to code 05, this entry is considered very problematic.


ZEK Code 99 - administrative entry

Code 99 is often used when an entry has been deleted or administratively adjusted. This code is not normally directly negative.



Practical example: How ZEK Codes influence credit opportunities

Example 1 - positive credit history

Mr Keller has taken out a loan and repaid it in full. This is saved in the ZEK with a positive code.

When he later applies for a new loan, the bank sees that he has already made one reliable repayment.

Example 2 - negative entry

Mrs Rossi had problems repaying a loan. A negative code is stored in the ZEK.

Whether she receives a loan today depends on how stable her current financial situation is.

How the ZEK influences loan approval


FAQ - ZEK codes and credit opportunities in Switzerland

What are ZEK codes and why are they important for loans?

ZEK codes are so-called creditworthiness indicators that are reported by banks and financial institutions to the Central Office for Credit Information. These codes provide information on how a borrower has behaved in the past with loans, leasing contracts or credit cards.

When a person applies for a loan, the bank usually first checks various databases, including the ZEK. There it can see whether previous loans have been repaid correctly or whether there are any indications of payment problems. This is exactly where the ZEK codes come into play.

A positive code can show that a borrower has reliably fulfilled their obligations. A negative code, on the other hand, can be an indication of previous difficulties. Banks use this information to assess the risk of a loan application. Nevertheless, a single code alone does not determine whether a loan is approved. Income, budget, employment and other factors also play an important role.


Which ZEK codes are considered positive or neutral?

Not every ZEK code is negative. Many codes merely show the current status of a loan or document correctly concluded financing.

For example, code 00 means that no negative information is available. Code 01 indicates that a loan has been repaid in full, while code 02 indicates that a loan is currently running and is being serviced correctly.

Such entries are not normally a problem for banks. In some cases, they can even have a positive effect because they show that a borrower already has experience with loans and has reliably repaid them.


Which ZEK codes are problematic for credit applications?

Some codes indicate difficulties with repayment. These include, for example, codes that indicate late payments, cancelled loan agreements or losses for lenders.

Codes such as 04 or 05 are particularly critical, as they can indicate that a credit agreement has been terminated due to payment problems or that a lender has suffered a financial loss. Codes relating to credit card problems can also have a negative impact on creditworthiness.

If such entries are present, banks usually scrutinise loan applications particularly carefully or reject them outright. Nevertheless, the decision always depends on the overall financial situation.


Can I get a loan despite a negative ZEK code?

A loan despite a negative ZEK code is possible in principle, but depends heavily on the type of entry and the current financial situation. Banks always check several factors at the same time.

A stable income, a long-term employment contract and a good budget can improve the chances of being approved for a loan. The age of an entry also plays a role. An older event is often rated less highly than a current problem.

In some cases, professional advice can help you to assess your chances more realistically and prepare your loan application better.

Check ZEK entry and understand credit opportunities


How long are ZEK codes stored?

The storage duration of ZEK entries depends on the type of event. Credit enquiries usually only remain visible for a limited time, while entries on credit agreements or payment problems can be stored for longer.

This storage serves to give banks an overview of a borrower's previous payment behaviour. At the same time, borrowers are to be protected from over-indebtedness by making several loan agreements transparently visible.

Anyone who would like to know exactly which entries are stored about them can request a self-disclosure from the ZEK at any time.


Are credit enquiries also stored in the ZEK?

Yes, credit requests are also registered in the ZEK. When a person applies for a loan, this enquiry is saved. This allows banks to see whether several credit enquiries have been made within a short period of time.

Many enquiries in a short period of time can be a warning signal for banks. They may suspect that a borrower is having difficulties obtaining financing or urgently needs money. It therefore makes sense to plan loan applications strategically and not make enquiries to many banks at the same time.


Can an old ZEK code affect my credit chances?

Yes, older ZEK codes can also have an influence on creditworthiness. However, they often lose their significance over time. Banks also take into account how long ago an entry was made.

If a borrower has a stable financial situation today and there are no current payment problems, an old entry can be weighted less heavily. Nevertheless, it makes sense to know your own ZEK situation and understand possible entries.

ZEK Switzerland: Entries, codes and credit check


Can I check my ZEK codes myself?

Yes, borrowers can check their own ZEK entries at any time. The so-called ZEK self-disclosure is available for this purpose. This makes it possible to view all stored information and understand what data is available about a person.

The self-disclosure shows, among other things:

  • Current loans
  • Credit enquiries
  • Leasing contracts
  • Credit cards
  • Possible payment problems

The enquiry can be made directly via the official website of the ZEK be provided.


Can an incorrect ZEK code be deleted?

If an entry is incorrect or out of date, a correction can be requested. Banks are obliged to correct incorrect data. It is therefore important to check your own entries regularly.

A self-disclosure helps to detect possible errors. If a problem is detected, a review or correction can be requested.


Why do banks check the ZEK for every loan application?

Banks are legally obliged to check the creditworthiness of an applicant. The aim is to avoid loan defaults and at the same time protect borrowers from possible over-indebtedness.

The ZEK provides banks with a central source of information about existing loans and previous payment histories. Together with income, budget accounts and other factors, this provides a comprehensive picture of an applicant's financial situation.
