Not School Related but Important! Please Help!

So, I bought something online, but I wasn’t home to receive it. It was sent to a secondary location, and I want to go pick it up now.

Here’s the problem:
It says a photo ID is required, but I don’t have mine. (It was taken by the post office when I got a passport, and they have yet to return it.) What should I bring in place? Will a picture of my ID work? Should I bring something else?

I genuinely have no idea, as it is the first time I’ve been in this situation.

Please help, Thank you!!
