Reason:

1. The national list of untrustworthy people is mainly aimed at those who have committed serious crimes, such as huge debts and refusing to perform legal judgments. Only overdue online loans 1300 yuan are not serious crimes;

2. The problem of overdue online loans is usually solved through civil disputes, and generally does not directly involve the list of national untrustworthy people;

3. At present, China's personal credit management is still in the development stage, and the relevant system is still not perfect. For small overdue debts, collection is generally adopted.

Summary: Overdue online loans 1300 yuan will not lead to the establishment of a national list of untrustworthy people. However, individuals should develop good repayment habits and repay their debts in time to maintain their credit records and credibility. When encountering any financial problems, it is best to consult professional institutions or lawyers to get accurate legal advice.
