What we can't do
We can't see your package. We don't have access to UPS, USPS or FedEx tracking systems, we don't look up tracking numbers, and we never ask for them. Only the carrier and the sender can see where a specific package is.
Live checks, every 30 minutes
- Carrier service alerts. We read the official service-alert pages: USPS, UPS, FedEx. An alert is linked to a facility when it names the facility's city or state.
- Weather. We read every active National Weather Service alert and match it to each facility's NWS forecast zone and county. We only show alert types that slow hubs and trucks: winter storms, ice, blizzards, hurricanes and tropical storms, tornadoes, floods, high wind, extreme cold and heat, and dense fog (which grounds air hubs).
- Visitor reports. The "stuck here too" button counts clicks per facility. One click per network per facility per day, and bursts are dropped. They are a signal, not proof: a few reports can come from one busy mailroom.
We keep the full history of alerts. When a serious storm or a carrier alert hits the facilities we follow, a dated page opens under Live delays and closes when the alerts end. If a source can't be reached, pages keep showing its last good copy and say when it was last checked.
Facilities and scan names
We cover 165 facilities, each with its own page. The list comes from carrier press releases, USPS Office of Inspector General audits, airport and local news, and the scan strings people post. Each facility page lists its sources. When the exact scan name comes from user posts rather than an official list, the page says so.
We explain 88 tracking messages, using the carriers' own help pages where they exist.
"Normal" wait times
Carriers don't publish how long packages sit at each facility. Our "normal time" and "worth acting" numbers are rules of thumb from how each kind of facility works (an air hub sorts overnight, a ground hub unloads trailers, a USPS Network Distribution Center handles containers that aren't scanned until opened) and from the delays documented in USPS Inspector General audits and carrier announcements. They are not carrier promises. We count business days because ground networks move little on Sundays and holidays.
Claim windows and search deadlines come from the carriers' official pages, linked wherever they appear. Facility facts were last reviewed November 14, 2026.
Corrections
If a scan name, facility or rule is wrong, see our corrections policy for how to tell us and how fixes work.
Independence
We're not affiliated with UPS, USPS, FedEx or any store. The site may show ads and affiliate links in the future. They won't change what a page says about a delay.
