How do I sort my contacts alphabetically by last name?
You can sort your contact list so that your contacts appear in a particular order. Sorting will only change the order in which contacts appear, it won’t reduce the number of contacts that appear. To sort your contact list alphabetically by last name, you can go to the main contact list. In the page menu on the left side, under “Filters & Sorting” select “Sort by.”
In the dialog that appears, you can select “Last Name” and then either “A to Z” or “Z to A.” When you apply that sort, it’ll show all of your contacts in order by last name, in alphabetical or reverse alphabetical order.
