Users can view their ADP check stubs online through the ADP website or via the company's applications for iOS, Amazon and Android devices, according to ADP. Each user must possess a unique username and password to access his account.
Activate a user ID using the website or the app or use a pre-existing one. Once logged in to a user account, view pay statements as well as other documents, such as time sheets and W2 tax statements, explains ADP. Only certain products and services available through ADP allow users to access the mobile app. Others must use the website login to view their personal documents..
