Postal Letter

What does it mean on USPS tracking when it says arrival at unit and sorting complete twice?

It says for the first arrival at unit and sorting complete right after those it says "notice left", now it says the same first two on my tracking page, does this mean they are attempting to re-deliver or did it not even get here yet?

1. It usually means that is was attempted. They will not try to deliver it again, unless you request it. You or someone should be home to sign for it. You could pick it up at your post office too.
