There is no clear limit on the number of credit inquiries in a year. However, frequent inquiries may have some impact on personal credit scores. Here is some relevant information:

1. There are two types of personal credit inquiries: personal-initiated inquiries and inquiries by financial institutions. Individual-initiated inquiries usually do not negatively affect credit scores, while financial institution inquiries may.

2. Financial institution inquiries usually occur in scenarios such as loan applications, credit card applications, etc. If there are multiple inquiries within a short period of time, they may be viewed by financial institutions as a higher credit risk.

3. Individuals can make credit inquiries through the official website of the People's Bank of China's Credit Reference Center or authorized third-party platforms to learn about their credit status.

4. Maintaining a good credit history, making timely repayments and avoiding late payments can improve one's credit score and reduce the frequency of inquiries by financial institutions.

Expanded Information:

The credit system is an important part of the financial system, which helps financial institutions to assess the credit risk of borrowers. Individuals should pay attention to maintaining their credit history and avoid unnecessary credit inquiries in order to maintain a good credit standing. At the same time, financial institutions will also take into account an individual's credit inquiry history as a factor in assessing credit risk when making credit approvals.
