Students may see DOI numbers written in two different formats. One format includes the letters doi and the number alone, and the other is a URL form. 

In May 2012, the American Psychological Association released a PDF-based update to its style guide, which included a new way of formatting DOIs for electronic references. (The new formatting replaces a listing such as doi:10.1037/rmh0000008 with a URL: Walden’s CAO announced at that time that Walden would not require these changes. Students who choose the updated format, however, should not be penalized. For more on this policy, see the Writing Center’s Electronic Source References page
