The Relevant Mobile Advertising program helps make marketing you see more personalized and useful to you across the devices and services you use. This program shares information with Oath (formed by the combination of AOL and Yahoo).
The advertising program uses online and device identifiers including browser cookies, advertising IDs from Apple and Google, and one created by Verizon, known as a Unique Identifier Header or UIDH. Unless you opt out of the Relevant Mobile Advertising program (and have not opted in to the separate 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 provide advertising services. Partners that receive the UIDH are authorized to use the UIDH only as part of the Verizon and Oath services and not for their own separate uses. More information about the UIDH can be found here.
