We’re taking steps to help restore trust in the nation’s phone network.

  • Establish trust in your Caller ID data and connect with customers.

  • To help you instill calling confidence with your customers, Verizon is working to meet the FCC mandated deadline of June 30, 2021, to enable STIR/SHAKEN across all our IP calling products. This set of industry standards is designed to reduce spam robocalls, prevent the “spoofing” of Caller ID data and help businesses improve voice security.

STIR/SHAKEN helps improve all calling experiences for:


  • Security icon

    Organizations that want to protect against telephone denial-of-service (tDoS) and other attacks


  • Buildings

    Enterprises managing a large number of inbound and outbound calls each day

  • Building icon

    Agencies that want to improve productivity and reach the public they’re supposed to serve

  • Conference room

    What is it?

    STIR/SHAKEN is a carrier-based Caller ID authentication that requires carriers to digitally sign calls originated by their customers. It uses the same public-key cryptography process that secures e-commerce websites.

    How does it help you?

    When people can’t trust that callers are who they claim to be, they stop answering even legitimate calls. Authentication—built right into our solutions with no extra effort needed on your part—can help ensure that customers feel more comfortable about saying hello instead of dismissing the call.
