### Claude EU Data Residency in 2026: What Anthropic Offers, and What European Teams Do Instead

Anthropic does not currently offer EU data residency for Claude — every prompt is processed on US infrastructure and constitutes an EEA-to-US transfer. Here is how that compares to OpenAI, Microsoft, and Google, what the EU-US Data Privacy Framework does and does not cover, and the supplementary-measure stack European teams deploy instead.
