# Why am I seeing 0000 for some purchases made with Link?

Your payment details are replaced with 0000 for certain Link purchases made with a US bank account. You can view past purchases and look up business contact information by navigating to the [Activity](https://app.link.com/activity) section of your Link account:
1. Log in to [Link](https://link.com)
1. Navigate to the [Activity](https://app.link.com/activity) section
1. Select the purchase you are looking for and click **Contact business** to locate their contact information
The 0000 that you see in place of your payment details doesn't denote any additional level of security for that payment.
