Customer Code Needed

I accepted an order a couple hours ago. It was a pickup for 1 item, some kind of Meta Quest thing. Easy enough, so I accepted and picked it up and headed to the customer. I get to the customer's house to deliver and see I need their code. No problem, I assume it's because it was an expensive item. So I ring the doorbell and wait. No answer. Ring again, wait, no answer. Ring a third time and no answer, so I submit for a return and take the order back to the store. It got me thinking. If we need a customer's code are we able to text them and receive it from them through text? My only apprehension would be that if you have to get a code, you dont have a way to take a photo or the order. So if the customer isn't home can you get their code on the phone or through text and leave it or do you have to get the code from them in person and hand them the order? I didnt want to risk it so I just returned it. 🤷‍♀️
