I lost my iPhone 13

No one can help you find it, but if you enabled Find My before it was lost log in to https://icloud.com/find using your Apple ID and click on the phone in the device list.

When you log in to https://icloud.com/find do you see your phone listed? If you see it but it shows “offline” then there is no way to track it.

Your Apple ID is your email address. Did you forget your email address?

Then not only can’t you find the phone, if you do find it you will never be able to use it.

There’s a slight chance this can help→If you forgot your Apple ID - Apple Support

Or you can just look at any email you received; your email address will be on it.

Then it is either powered off, the battery has run down, or it doesn’t have a data connection. There is no way to track it under any of these conditions.
