You must also make it clear that the data is available under the Open Database Licence, and if using our map tiles, that the cartography is licenced as CC BY-SA. You may do this by linking to this copyright page. Alternatively, and as a requirement if you are distributing OSM in a data form, you can name and link directly to the licence(s). In media where links are not possible (e.g. printed works), we suggest you direct your readers to openstreetmap.org (perhaps by expanding 'OpenStreetMap' to this full address), to opendatacommons.org, and if relevant, to creativecommons.org.
