No other source offers a better station list than OPIS.
Unlike companies that periodically update station information through phonebook records, the OPIS station list is never out of date. OPIS captures brand changes quickly because it gets the price codes from each station and their network id changes if anything at the site changes.
Being part of the industry, OPIS knows better than any other information source if a station closes its doors or sells diesel. The OPIS station list is scrubbed and updated daily. It's the perfect point-of-interest for automotive companies and personal navigation devices.
Downloading the station list is easy. You can pull the flat pipe delimited file from an ftp site. You will have complete flexibility and be able to capture brand changes and get amenity information in near real-time.
