5-1-1 — United States and Canadian travel and traffic information number
5‑1‑1 (511) is a national short telephone code in the U.S. and parts of Canada that provides local travel information — traffic, road conditions, transit and traveler alerts by phone, web and apps.
Overview
5-1-1 (spoken "five-one-one" or "five eleven") is a three-digit telephone number used for traveler information in the United States and in some parts of Canada. It was created to provide an easy-to-remember way for the public to obtain current information about traffic, road conditions and transit options. Services are typically free to call from landlines and mobile phones (mobile access) and are often paired with web pages and smartphone applications.

Characteristics and services
5-1-1 systems vary by jurisdiction but commonly offer:
- Real-time traffic incident reports and congestion updates.
- Roadwork and construction notices, lane closures and detours.
- Weather-related advisories (e.g., winter driving, chain requirements).
- Public transit schedules and service disruptions.
- Ferry and seasonal route information where applicable.
Origins and development
The 511 concept stems from the set-aside of N11 telephone codes for special services. In the early 2000s the Federal Communications Commission, responding to recommendations from transportation authorities, designated 5-1-1 for traveler information so that states and provinces could deploy a consistent, easy-to-use contact number. Implementation has been carried out locally, so features and coverage differ by agency.
Usage, regional differences and access
Because deployment is managed at the state, provincial or regional level, the experience of calling 5-1-1 or using a 511-branded website varies. Calls are commonly routed to regional call centers or automated voice systems and are often supplemented by maps and live traffic cameras on agency web pages. Many jurisdictions also publish 511 data feeds that third-party mapping apps and in-vehicle navigation systems can use to show incidents and travel times (traffic and travel).
Accessibility, technology and notable facts
Most 5-1-1 services support multiple languages and offer TTY access for callers with hearing or speech impairments. Modern 511 systems combine telephone service with web, smartphone apps and machine-readable data to reach drivers, transit riders and fleet managers. Because each region controls its own service, travelers should check the local 511 website or call the number in their area for the most accurate, up-to-date information.
