Does anyone know delivery companys that deliver big packages?

I brought a 62inch Television online and i recieved a tracking number to whoever is delivering it but the only thing is i don't know who the tracking number belongs to...It does not look like a fedex or ups or usps tracking number...So does anyone know who companys use to deliver big heavy items like a projector television if so do you know the web address or phone or any way i can find out?
