Most of us have filled online forms hundreds of times, but there’s always that one field that makes you pause: Address Line 2. I remember ordering something online and staring at the checkout form wondering if Address Line 2 was mandatory or if I was supposed to write something specific there. If you’ve ever felt the same confusion, you’re definitely not alone — millions search this every month.
Quick Answer:
Address Line 2 is an optional field used for extra details like apartment numbers, building names, floor details, landmarks, or additional delivery instructions.
What Does “Address Line 2” Mean?
Address Line 2 is an optional part of your address used to add extra information that helps couriers deliver your package accurately. It’s not required in every address, which is why many people leave it blank.
You should use Address Line 2 for additional details that don’t fit in the main Address Line 1.
Example:
Address Line 1: 123 Main Street
Address Line 2: Apartment 4B, Second Floor
In short:
Address Line 1 = Primary address
Address Line 2 = Optional extra information
