Read this before you rely on it
The holder is the company NANPA assigned the codes to, under the legal name it registered. That name can differ from the brand customers see, and one brand can hold codes under several legal names.
Numbers port. A number in one of these prefixes may now be with another carrier, so the prefix alone does not say who serves it today. To see the holder of the block behind a number, use the carrier lookup.
