Title: See @KennWhite: https:&#x2F;&#x2F;twitter.com&#x2F;kennwhite&#x2F;status&#x2F;525110471733817344<p>Verizon Wireless is injecting a UID into all HTTP requests made on the VZW network, regardless of whether or not you&#x27;ve opted out of their Customer Proprietary Network Information (CNPI) options.<p>It&#x27;s injected at the network level- So it tracks across browsers and ignores &#x27;private browsing&#x27;, do-not-track headers, overriding the UIDH in the client&#x2F;curl, everything. My confirmation showing the headers only appearing in unprotected HTTP requests (disappearing when VPNed):<p>https:&#x2F;&#x2F;twitter.com&#x2F;rammic&#x2F;status&#x2F;525360201361530880<p>If you&#x27;re on the VZW cell network and not using wifi, you can check your own ID here (via @j4cob):<p>http:&#x2F;&#x2F;uidh.crud.net&#x2F;
