Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) officials, including a CBP officer who was on the scene when another officer shot a U.S. citizen, are using a free walkie talkie app called Zello to coordinate their operations, 404 Media has found.

The findings give insight into the sort of technology that ICE and CBP are relying on during the Trump administration’s ongoing mass deportation effort. Zello was previously criticized for allowing at least two January 6 insurrectionists who broke into the Capitol to coordinate on the app that day, and for hosting hundreds of far-right channels.

404 Media reviewed multiple pieces of bodycam footage from Chicago which showed CBP officials using the app. We also confirmed that multiple Zello user accounts on the app are associated with ICE email addresses, with some usernames containing acronyms such as ERO, which stands for ICE’s Enforcement and Removal Operations, and verified that multiple ICE group channels exist on the platform. Some of these channels have names mentioning immigration operations, “surveillance,” and “strike team.”

Do you know anything else about Zello? Do you work at ICE or CBP? I would love to hear from you. Using a non-work device, you can message me securely on Signal at joseph.404 or send me an email at joseph@404media.co.

Zello is a smartphone app that acts much like a push-to-talk walkie-talkie. Users can communicate directly with one another, or create and join larger channels with groups of participants. On its website, the app claims to have 5 million active monthly users. The app offers a free version that anyone can download and start using, and a paid “Zello Work” option which has more features.

How ICE and CBP Use Free Walkie-Talkie App ‘Zello’ to Power Their Operations

404 Media found multiple users of Zello, an app previously used by January 6 insurrectionists, linked to ICE officials. An officer at the scene of an CBP official shooting a U.S. citizen also used the app.

ICE’s Facial Recognition App Misidentified a Woman. Twice

When authorities used Immigration and Customs Enforcement’s (ICE) facial recognition app on a detained woman in an attempt to learn her identity and immigration status, it returned two different and incorrect names, raising serious questions about the accuracy of the app ICE is using to determine who should be removed from the United States, according to testimony from a Customs and Border Protection (CBP) official obtained by 404 Media.

ICE has told lawmakers the app, called Mobile Fortify, provides a “definitive” determination of someone’s immigration status, and should be trusted over a birth certificate. The incident, which happened last year in Oregon, casts doubt on that claim.
