Trace my iPhone with imei and serial number

Sorry, but you cannot do this.

Apple does not use the IMEI or Serial Number to locate an iPhone.

You cannot. You can only track a device using FindMy iCloud.com/find

You cannot track the location of an iPhone using the IMEI or Serial Number. The only way to track an iPhone is through the Find My app and only if it was activated on the iPhone prior to it being stolen/lost.
