Ms. Sara Dawson

Apartment 568
Dallas TX 99999

Receiver’s Name
Street Address
City, State, ZIP Code

Mr. George Watson
568 Maven Street, Unit 20
Austin, TX 56789

USPS also states that placing the unit number or apartment name on a separate line such as “Address Line 2” will be a non-standardized way, as in the example below.

Mr. George Watson
568 Maven Street
Unit 20

One of the best ways of improving the usability of an address form is by hiding the “Address Line 2” field behind a link.

Displaying just one permanent Address Line 1 and an optional Address Line 2 prevents users from second-guessing their input action. However, it’s also vital that the subset of users who require the second line be able to spot the link.

But the lesser the form fields, the better the user experience. Not only does it reduce typing time and increase process speed, but it also makes everything less ambiguous and intimidating.

However, the “Address Line 2” should only be hidden behind a link in places where the majority of site users don’t need the field. In situations where the majority of users require the field, it should be made permanently visible.

UX Implementation Details for Address Line 2

Here are some UX implementation details for Address Line 2 to make sure you get it right.

#1. Whether collapsed or expanded, all the form fields, including address lines, must be marked as required or optional. The absence of these markings can lead to severe usability issues. This includes unnecessary time spent on the form when it was not mandatory to fill a field or dealing with validation errors by not filling the field that had to be filled.

#2. While using revealing links for form fields like “Address Line 2,” make sure you include it in the keyboard tab flow. This is because most users use keyboard tab keys to navigate through form fields.

#3. Additionally, ensure tooltips and other helpful links are skipped in the tab flow as they can create unnecessary confusion.

#4. The link revealing the “Address Line 2” field must be appropriately styled to convey that it expands into an additional form field. You can either use text or an icon like “+” to convey this.
