Loropen: One Address, Every French Public Register
Loropen cross-references French public datasets—from parcels and buildings to company records, property sales, energy diagnoses, risks, and planning—from an address, SIREN, or company name.
Field notes
Loropen treats an address, company identifier, or organization name as the joining key across French public datasets. Its stated coverage includes 52-table-per-department building data, 29.9 million SIRENE legal units, 20.4 million property transfers grouped by deed, and energy diagnoses refreshed daily. The operator says source files are checked through fingerprints, table counts, and row counts before publication, while accounts remain manually approved.
