1CB.kz - Первое Кредитное Бюро is a free Android application developed by JSK First Credit Bureau. This app provides the users with the ability to obtain their credit report, monitor their credit history, and challenge credit reports without visiting the office.

With 1CB.kz, you can obtain your personal credit report for free once a year, in accordance with the Law on Commercial Bank. You only need to have a digital signature to use this service. Additionally, you can keep track of any changes in your credit history by subscribing to credit control. This feature is similar to SMS banking and will notify you via mobile phone or email if there are any changes in your credit history.

Moreover, 1CB.kz offers the possibility to challenge information in PKO. This is important because credit history is based on the information provided in the PKB information providers' database (banks and financial institutions), and PKB may not make changes or additions to your credit history.
