Found A Card On My Porch Today, Not Sure What To Do About It.

Found a card on my porch tonight that says “certified process server, Tenth judicial circuit” with a name and number, asked me to call or text the number, had a date and time that this person visited my house while I was gone.

Also says “I have important court papers for you” and “you have court on 3/12/25”. I haven’t heard of any court dates before, and can’t think of a reason for me to have to appear in court. What should my next steps be? I don’t know what a certified process server is, or what a judicial circuit is

Edit for extra info: There was no intended recipient on the card, so I’m not even 100% sure it’s for me. Is this a cause for concern?
