Start with locations. Use location_id as text to join contacts, classifications, and any included historical contacts. Keep postal codes as text so leading zeros survive import. Blank values mean the source did not supply a usable value or the detail was withheld after review.

Latitude and longitude are directory coordinates and may not identify a public entrance. A contact can serve more than one location. Review the included field dictionary, schemas, samples, and statistics before mapping fields into your own system.

The same included tables are available in CSV, JSON, and SQLite. Choose one format for a workflow to avoid counting a location more than once. If a transfer fails, return to your account download page and contact support with the order, database version, and error.
