Our Relevant Mobile Advertising and Verizon Selects programs help make advertising you see more personalized and useful by using certain customer information we have to connect that advertising with your interests. These advertising programs share information with Oath (formed by the combination of Yahoo and AOL) and the UIDH is used in these programs.
Details about the data the advertising programs use is available in the FAQs we provide for Relevant Mobile Advertising and Verizon Selects. You can choose whether to be a part of these programs at any time through opt-out (Relevant Mobile Advertising) or opt-in (Verizon Selects) choices found on you privacy settings online, on your device in MyVerizon, or by calling 1-(866) 211-0874 (for Relevant Mobile Advertising opt-out). You also have choices about Oath's use of information it collects and uses for advertising purposes.
We do not share information that identifies you personally as part of these programs other than with vendors and partners who do work for us. We require that these vendors and partners protect the information and use it only for the services they are providing us.

What advertising programs use the Unique Identifier Header (UIDH)?
What is a UIDH?
Header information is included in all web traffic and includes information such as the device type, preferred language, and content support so that the site receiving the request knows how to best display the site on the phone or other device that sends the request. Verizon Wireless includes a Unique Identifier Header (UIDH), a random string of characters, in the address information that accompanies some of the Internet (http) requests transmitted over our wireless network.
Unless you opt out of the Relevant Mobile Advertising program and have not opted in to the Verizon Selects program, a UIDH is included in the address information of Internet requests going to Verizon companies (including Oath). In addition, with your opt-in consent, for example when you opt in to the Verizon Selects program, the UIDH may be shared with partners who help provide advertising services. Verizon partners are authorized to use the UIDH only as part of Verizon and Oath services and not for their own separate uses. The UIDH does not contain any personally identifiable data and it does not broadcast individuals' historical web browsing activity to advertisers or others.
Why and how is a UIDH used?
The advertising programs use online and device identifiers, including browser cookies, ad IDs from Apple and Google, and the UIDH. The identifiers are used to make our advertising programs better by, for example:
Does the UIDH affect my privacy?
The UIDH does not contain any personally identifiable data and it does not broadcast individuals' historical web browsing activity to advertisers or others. As explained in more detail in response to question #2, Verizon only includes the UIDH in address information of Internet requests in specific circumstances. In addition, other privacy protections are designed into the UIDH, for example, it changes automatically and frequently.
Is the UIDH still present if a customer has opted-out of the advertising programs?
Verizon Wireless stops inserting the UIDH after you opt out of the Relevant Mobile Advertising program, unless you have also opted in to the Selects advertising program. The UIDH will continue to appear for a short period of time while we are updating our systems. If you choose to participate in Verizon Selects, the UIDH will be present even if you have also opted-out of the Relevant Mobile Advertising program.
