Include Both Numbers and Letters
If you register the [Farmers Insurance][] website, be sure to pay attention to the following guidelines when selecting your username: * Must be between 6 and 16 characters long * It may be any arrangement of letters and numbers but it must include at least one letter and one number
Why in the world would a username be required to contain numbers?
