That looks like URL-encoded text, not an actual tracking number.\n\nIf you send me the *actual tracking code* (e.g. something like \u201c1Z999AA10123456784\u201d, \u201c9400 1000 0000 0000 0000 00\u201d, etc.), I can likely identify the carrier using its format. Would you like to provide the code so I can help?"
