Wireless services account for about 70% of Verizon Communications' total service revenue and nearly all of its operating income. The firm serves about 93 million postpaid and 21 million prepaid phone customers (following the acquisition of Tracfone) via its nationwide network, making it the largest US wireless carrier. Fixed-line telecom operations include local networks in the Northeast, which reach about 29 million homes and businesses and serve about 8 million broadband customers. Verizon also provides telecom services nationwide to enterprise customers, often using a mixture of its own and other carriers' networks.

Verizon is a leader in the U.S. telecommunications industry. The company was created in July 2000 when Bell Atlantic and GTE merged.
