Hazmat Registration Search vs Haz Aware Usage & Stats

The Hazmat Registration Search mobile app allows you to search the US Department of Transportation’s Hazmat Registration database to determine the status of a company’s hazmat registration. Basic and advanced search functions allow you to search using registration ID, USDOT #, postal code and/or company name. The basic search function provides one field to enter a search value and can return a list of many results. The advanced search function provides multiple fields to enter search values and can return a shorter refined list of results. Once a search is performed, a list of companies is returned. By selecting a company, you can expand the details of a specific hazmat registration record. A PDF function allows you to generate a PDF version of the Hazmat Registration certificate that can be printed, saved or emailed. The web based version of this application can be accessed at https://portal.phmsa.dot.gov/HazmatRegistrationSearch.
