WhatsApp usernames: benefits and risks
WhatsApp is introducing usernames so users can hide their phone numbers from people who don't already have them; usernames can be reserved now and the full rollout is planned in the coming months. German consumer protection (Verbraucherzentrale Nordrhein-Westfalen) lists advantages such as reduced visibility of numbers in groups and optional pseudonyms, and warns of disadvantages: Meta will still hold phone numbers, usernames could enable cross-platform profiling if imported from Instagram/Facebook, and users should avoid using real names. The consumer body also recommends enabling the "username key" (a PIN) to control who can contact you. Username rules: 3–35 characters, lowercase letters, numbers, underscores and dots, and not digits-only.
Feature rollout from a major platform (Meta/WhatsApp) affects user identity handling and cross-platform profiling; has implications for privacy, identity signals and tracking in the advertising ecosystem.

Permutive and TransUnion Partner to Enhance Sell-Side Curation
Permutive and TransUnion have announced an integration that enables publishers using Permutive's DMP to match their first-party audience data with TransUnion's identity graph and activate TransUnion audiences across Permutive's global publisher network. This addresses the limited addressability of the open internet, where only about 30% of traffic is addressable via cookies or alternative IDs, by leveraging multi-signal identity strategies. Early testing with a financial services advertiser showed a 12x increase in addressable impressions, a 5x increase in consumers reached, and a 170% overshoot of the KPI target. The partnership aims to provide a viable alternative to walled gardens, reduce data fees, and monetize previously unsold inventory, ultimately improving campaign accuracy and performance.
