A global corpus of 423,933 text entries containing personal location and travel information, annotated for Personally Identifiable Information (PII). The dataset is part of the larger PII-Masking-3M collection by Ai4Privacy and was last updated in June 2026. It contains over 3.3 million annotations across 34 label types, 30 languages, and 37 regions.

Use Cases

• Train PII detection models based on the 34 distinct annotation labels.
• Benchmark multilingual NER systems using the 30 languages covered.
• Develop privacy-preserving text processing for applications handling travel or location data.
• Study geographic and linguistic variations in PII expression across 37 regions.

Strengths

• Large annotation volume with 3,323,062 PII annotations.
• Broad multilingual coverage across 30 languages.
• Explicit focus on location and travel PII, a specific and critical privacy domain.
• Part of a larger, documented corpus (PII-Masking-3M) with a referenced source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-06-03).
