A Pearson MathLab access code is a requirement for students who intend to register for any academic course that requires the use of the program. As of 2015, Pearson generally packages codes with textbooks, but users can also purchase them as part of a standalone access code kit.
Alternatively, students can purchase instant access to the MathLab program online by using their PayPal account or a credit card. Pearson only provides access codes to textbooks that are sold directly from an authorized reseller or a campus bookstore. Students who purchase access codes or textbooks from third-party resellers may be unable to register because the codes may no longer be valid.
