If your package is out for delivery but not delivered it could be that the package is still with the USPS carrier or UPS carrier and has not made it's way to you yet.
Or the package may have gotten scanned wrong to say out for delivery when it has not left yet.
For USPS and UPS if the package is not at your address by 5:00 PM to 8:00 PM then it likely won't be there until the next day.
You cannot pick up a package from a USPS regional facility.
When a package goes to a USPS regional facility it means the package is at a large warehouse and is being sorted through machines.
Before being sorted the package is in bins and on trucks so they would not be able to find the package for you or get it for you until it actually go through the sorting machine.
Also the USPS sorting facility does not allow public access except for the workers.
Processed through regional facility means that the package has arrived at the regional facility which is the facility closest to the shipper and the package has been processed through the facility and is on it's way to you.
Once a package leaves a regional distribution facility it can take a few days or so for your package to arrive.
The time it actually takes for your package to arrive after leaving the regional distribution facility depends on where you're located.
If you're located 1,000 miles away or 500 miles or more from the regional distribution facility then it may take 4 days for your package to arrive.
If you live within 200 miles or less than the package may arrive within a few days.
When a packages arrives at the USPS regional destination facility the package will then be sorted and then put on another truck and then sent to your local post office for final delivery.
The regional facility is the facility where the package is first sent to from the shipper and the regional destination facility is usually the facility that is closer to your location.
Then from there the package goes to your local post office.
Departed regional destination facility means that the package has been sorted and put on a truck for delivery to it's final destination which would be your local post office.
Then from there your package will be delivered from your local post office or if you get your mail at the post office you can pick the package up at the post office once it's been sorted and ready at your local post office.
On track to be delivered or on track on USPS means it's on it's way to the destination.
The package could reach it's final destination soon or it may take a few days.
The item currently in transit to it's destination means that processing at one specific location has concluded, the packages getting ready to be moved again (transit), and is either headed to another processing facility or is going to be dropped off at the local post office and sent out for delivery.
A package can get stuck in processed through facility due to tracking errors or the package may have not been scanned again for awhile.
USPS tracking is not very reliable and sometimes scans get missed although if it's moving within the network it won't be scanned again until the package reaches your local destination facility or local post office.
A USPS regional facility is a sorting facility close to where the shipper shipped the package.
The USPS picks up the packages from the shipper or from the local post office and then takes them to a USPS regional facility where they are sorted and then sent on their way.
Then the package reaches a USPS destination facility which is local to your are and then the package goes to your local post office.
A USPS destination facility is a USPS sorting facility that serves the post offices and postal customers in that region.
If your package has just arrived or been processed at a USPS destination facility, that means it has reached the second-to-last leg of its journey.
“Arrived” and “Processed” might be used interchangeably; I've had parcels scanned as both arrive and processed, and then also just scanned arrived before it departed.
Basically when the USPS package gets to the destination facility it will then be sent out to your local post office for final delivery.
When a package leaves the regional destination facility the package then goes to your local post office for delivery.
The USPS destination facility is the USPS sorting facility that serves your region and local post office.
Or for UPS the package goes to the UPS facility closest to you and then gets delivered.
The stages of USPS tracking are.
USPS Pre-Shipment. "Pre-Shipment Info Sent to USPS, USPS Awaiting Item": USPS has received the electronic transmission of the manifest shipment information from the sender.
USPS In Transit to Next Facility.
Out for Delivery.
When USPS says the item is currently in transit to the destination it means the package is traveling through the USPS network and it could mean that the package is on it's way to your local post office or to another USPS sorting facility.
The USPS item currently in transit to the destination means it's traveling and will get to you most likely on the scheduled date.
Out for delivery on the tracking does mean you'll get your package today.
When your tracking updates to out for delivery you should expect your package to get delivered that day.
In transit means your package is moving within the USPS network.
When a package is in transit it means the package is moving within the USPS network and it's on it's way to your location.
The package in transit means it's most likely on a semi truck heading down the road to either another sorting facility or to your local post office.
Arrived at your local post office means the package is getting ready for delivery and out for delivery means the package is out for delivery and will be delivered that day to you.
In transit does not mean out for delivery on USPS.
When a package says in transit it means that the USPS package is traveling within the USPS network such as on an airplane, semi truck etc.
When the USPS tracking says out for delivery then the package will be delivered that day but in transit just means it's traveling from a USPS sorting facility to another sorting facility or to your local post office.
