A lookup shows MetroPCS when the number is on T-Mobile's mobile network.
Carrier records use a company's legal or historic name, so a lookup can show MetroPCS while the person's bill says T-Mobile.
Numbers can also move between carriers, so a lookup reads the number's carrier today, and a number with a MetroPCS prefix can show another company if it was ported.
