A lookup shows Bandwidth when the number comes from a service that gets its numbers there.
Bandwidth rarely sells phone service to the person using the number. Internet calling apps, VoIP phone systems, call centers and business phone services get their numbers from carriers like Bandwidth, so a lookup shows the carrier behind the service, not the service itself.
Numbers can also move between carriers, so a lookup reads the number's carrier today, and a number with a Bandwidth prefix can show another company if it was ported.
