What does “In Transit to Next Facility” mean?
It means the package left its last scan point and hasn't been scanned at the next one yet. USPS's tracking help lists In Transit with Arrived at USPS Facility and Departed USPS Facility, and says the package "is currently being processed or transported to your delivering Post Office." It tends to appear when a package has gone a while without a new scan, so it tells you less about where the package is than an arrived or departed scan does.
What does it mean for a letter?
A letter never shows these words, because its tracking comes only from the sorting machines that read its barcode. Between two plant scans a letter simply has no new event. PigeonTrail keeps showing it as "In the mail" with the city of its last scan, and the route map shows where it was last seen.
How long can a package stay in transit to the next facility?
Usually a day or two. USPS doesn't publish a limit, and long routes, weekends and the December rush all stretch the time between scans. The useful date is the expected delivery date on the tracking page, because that is what USPS is aiming for, and a package in transit on that day can still arrive in time.
A letter's trip is set by its service standard, which for a stamped First Class letter is 2 to 5 delivery days depending on the two ZIP codes. Letters often go a day without a scan between plants, and a letter sent across the country can pass through several plants on the way. Our delivery time tool shows the standard for any two ZIP codes.
What should you do if it stays in transit too long?
Wait until the expected delivery date has passed, then check again the next day. If a package is still in transit after that, USPS's route is a Missing Mail search on usps.com, and the sender can also ask the carrier to look for it. A letter with no new scan for several days is often already delivered, because letters to about 17% of ZIP codes are sorted by hand at the last step and get no more scans after the destination plant.
That is why PigeonTrail waits until a letter is more than a day past USPS's expected date, or five days without any scan, before it calls the letter behind. If you're on Pro, we email you then, so you can reach your buyer before they write to you.
Questions
Is In Transit to Next Facility a delay?
Not by itself. It means the package is between scans. It becomes a delay only when the expected delivery date passes and nothing new has appeared.
Why has my package said In Transit for days?
Long routes, weekends and busy seasons can leave a package without a new scan for a few days. If the expected delivery date has passed, start a Missing Mail search on usps.com.
