The National Corrections Intelligence Platform

About Jail411

Jail411.com is the most comprehensive corrections facility directory in the United States, cataloging 6,747 jails, prisons, and detention centers across all 50 states and the District of Columbia. We combine authoritative government data with original reporting to serve as a definitive reference for the U.S. corrections system.

Our Mission

Transparent, accurate information about correctional facilities should be available to everyone who needs it — from families with incarcerated loved ones to attorneys, journalists, and policymakers. Jail411 exists to close the information gap between the public and a corrections system that houses over 1.9 million people.

Data Sources & Methodology

Our facility database is built from multiple authoritative government sources, cross-referenced for accuracy:

• Homeland Infrastructure Foundation-Level Data (HIFLD) — Primary dataset for facility locations, addresses, and classification maintained by the Department of Homeland Security
• Bureau of Justice Statistics (BJS) — Census of Jails and National Prisoner Statistics for capacity, population, and jurisdiction data
• Federal Bureau of Prisons (BOP) — Official records for all federal correctional institutions and detention centers
• State Departments of Corrections — Direct sourcing from state DOC websites for facility status, security classifications, and contact information

Each facility record includes address, phone number, facility type, security level, jurisdiction, and geographic coordinates. Records are verified against multiple sources before publication and reviewed on a rolling basis.

Editorial Standards

Our news coverage follows standard editorial practices:

• Source verification — All reporting is based on official records, court documents, government reports, and on-the-record statements
• Accuracy — Claims of fact are attributed and verifiable. We correct errors promptly and transparently
• Independence — Jail411 is independently operated. We accept no funding from corrections agencies, private prison companies, or advocacy organizations
