# Loading timestamp root certificate

<mark style="color:red;">**This only applies to documents signed on 11 and 12 June 2025**</mark>

The timestamp certificate proves that your document was signed at the stated time. In order to verify that the timestamp certificate in your downloaded document is valid, you might need to load in the timestamp root certificate.

To load it in, please follow the steps below:

1. Download the GlobalSign root certificate from [here](https://secure.globalsign.net/cacert/root-r6.crt).

   1. If you're unable to access that link, please visit [GlobalSign's CA repository](https://support.globalsign.com/ca-certificates/root-certificates/globalsign-root-certificates) and download the **R6 GlobalSign Root Certificate.**
