If you want to stop receiving paper statements, go to your account settings or e-Statement in the app/Internet Banking if your bank offers this feature, or request to switch to electronic statements from customer service or a branch.
Steps
Before canceling, make sure your email address and mobile number are up to date and that you can download statements electronically.
Also, ask your bank if stopping paper statements will waive any fees; this varies depending on each bank's fee schedule.
The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
