No, a credit or loan denial does not affect your credit score. The credit report will indicate that you made an application, but it will not show if the loan was approved or not.
The score, however, can be slightly affected by the number of inquiries made by the companies. This is because the account keeps a record of the number of queries made and how close in time they are to each other.
However, the number of inquiries will not impact your credit score if the inquiries are spaced enough.
