In most cases, parking tickets do not directly impact your credit score because parking tickets are not considered a form of credit or debt. However, unpaid parking tickets can have other consequences that may indirectly affect your credit score.
For example, if you have unpaid parking tickets, the government or the parking authority may send them to a collection agency. Once a collection agency gets involved, they may report the unpaid tickets to credit bureaus, which can negatively impact your credit score. This is because unpaid debts or collections can stay on your credit report for up to 7 years and can be seen by lenders and other creditors.
