Woofun AI reports that authentication emails from Anthropic's AI assistant, Claude, now display rough login locations such as country, region, or city. This data is inferred from IP addresses, network connections, and device information rather than precise GPS coordinates, meaning locations may not match actual user positions when using VPNs or proxies.

Anthropic states this collection supports security, anti-fraud, and terms enforcement. The feature has heightened sensitivity among Chinese users, where cross-border access is common, coinciding with reports of account suspensions and re-verification demands referred to as an "account suspension wave."
