Is it possible to track the phone with imei number if lost?

My teenager lost their phone at the park yesterday and it’s totally dead, so the regular location sharing apps aren’t working. I kept the original box and have the 15-digit serial code written down, but I have no idea how ordinary people are supposed to use it to locate a device. Has anyone here actually had success finding a missing cell this way, or do I have to somehow get the service provider or police involved to ping it?

IMEI tracking is complicated; usually, only service providers or authorities can ping a phone using it. Keep in touch with your carrier for advice.
