Is it pick up or pickup?
Also, does pick up truck have a hyphen?
I've always used hyphenation for the compound modifier. Pick up for the verb and pickup for the truck or any other time that it is used as a noun. So I would say "Drive your pickup to pick up the kids at the pick-up location." However the distinction between adjective and noun seems to be going away over time.
Regarding this, will be picked up or will be pick up?
I think for pickup is more common in colloquial English, to be picked up is more wordy and sounds more formal. When used as a noun or adjective, it's a single, compound word. When used as a verb, it's split into the original two words: pick up your clothes.
Instead of the delivery date customer and vendor can send the pick-up date, which is the time at which a freight forwarder picks up the required materials or products from the vendor.
