Tracking Number Troubleshooting: What to Do When Your Customer Can't Track a Shipment
"My tracking isn't working" can mean four or five completely different problems — here's how to figure out which one you're actually dealing with.
A customer message that says "my tracking isn't working" is rarely one specific problem. It could mean the number was typed incorrectly, the tracking page hasn't updated yet, the link they clicked was broken, or the shipment genuinely has an issue. Each of these needs a different response, and guessing wrong wastes time on both sides — and can turn a five-minute fix into a frustrated back-and-forth.
This guide walks through the most common causes behind a customer's tracking complaint, how to tell them apart quickly, and what to actually say at each stage so the conversation resolves instead of dragging on.
The Four Most Common Causes
The number was entered incorrectly
Most common causeA single mistyped or miscopied character will return a "not found" result on most carrier sites, which looks identical to a genuinely broken tracking number. This is almost always the first thing to rule out, since it's the easiest to fix and the most frequent cause overall.
The customer is searching the wrong carrier's site
Second most commonIf a customer pastes a number into the wrong carrier's tracking page — a UPS number into FedEx's site, for instance — they'll get a "not found" error even though the number itself is completely valid.
The shipment hasn't been scanned yet
Not a real problem, but reads like oneA tracking number generated right after a label is created can sit with no movement for hours, sometimes a full day, before the first scan. To a customer, this looks identical to a broken number, even though it's entirely normal.
The tracking link itself is broken or expired
Less common, but realSome marketplace-generated tracking links can point to a cached or outdated page, especially if an order was edited or reshipped after the original label. In these cases the underlying tracking number is often fine — the link that was shared is the actual problem.
It's worth noting that these four causes aren't equally likely. In practice, a mistyped number or wrong carrier site accounts for the large majority of complaints — genuine carrier issues are comparatively rare. That means the fastest path to resolving most tickets is ruling out the simple explanations first, rather than assuming something has actually gone wrong with the shipment itself. Jumping straight to "let me contact the carrier" for what turns out to be a typo wastes time on both sides and can make a minor mix-up feel like a bigger problem than it is.
Diagnosing It Fast
Once you've read the customer's message, the goal is to work through the likely causes in order of probability rather than guessing randomly. The five steps below move from the fastest checks to the ones that actually require contacting the carrier, so you're not escalating anything until the simpler explanations have been ruled out.
Pull the tracking number from your own label history or confirmation email rather than trusting what the customer typed — this immediately rules out a copy-paste error on their end.
Check the number's format or your own shipping record for the carrier name, then search it on that carrier's own site directly rather than a third-party tool the customer may have used incorrectly.
If it shows "label created" or "pre-shipment," the number is working correctly — the shipment simply hasn't been scanned yet, which is the most common false alarm.
If your notification includes a clickable link, click it yourself to confirm it resolves correctly — a broken or mistyped link is a different fix than a genuinely inactive tracking number.
If the number is correct, the link works, and there's still been no movement well past that carrier's normal window, that's the point to actually contact the carrier rather than continuing to reassure the customer.
Skip the guesswork — see the real status yourself
Shippo keeps every label you've created in one dashboard with its live status, so you can confirm exactly what stage a shipment is at before replying to a customer — instead of relying on whatever they tell you they saw on a carrier's site.
Check Your Shipment StatusQuick Reference: Cause, Symptom, Fix
| Symptom | Likely Cause | What to Tell the Customer |
|---|---|---|
| "Not found" error | Mistyped number or wrong carrier site | Re-send the exact number and a direct link |
| No movement for hours | Label created, not yet scanned | Explain the normal pre-scan delay window |
| Link doesn't open correctly | Broken or outdated tracking link | Send a fresh link from the carrier's own site |
| No movement for days | Genuine delay or exception | Escalate to the carrier and give a real update |
What to Actually Say
Once you've identified the real cause, the reply itself should be short and specific rather than generic reassurance. A few starting points, adapted to your own voice:
- If it was a typo or wrong site: "Here's the tracking number again along with a direct link — it looks like the earlier search may have had a small typo."
- If it's pre-scan: "Your label has been created and the shipment is with the carrier now — tracking usually starts showing movement within [X hours], which is completely normal for this service."
- If the link was broken: "That link looks like it didn't load correctly on our end — here's a fresh one directly from [carrier]'s tracking page."
- If there's a genuine delay: "I've reached out to the carrier about this shipment and will follow up as soon as I hear back — thanks for your patience."
Keep a saved reply template for each of the four causes above. Most tracking complaints fall into one of them, and having the wording ready cuts response time down to a copy-paste rather than writing a fresh explanation each time.
Frequently Asked Questions
How do I know if a customer's "not working" tracking number is actually mistyped?
Pull the number from your own records and search it yourself. If it returns a valid result on your end but not the customer's, the difference is almost always a typo or an extra character introduced when they copied it.
Should I apologize even if the tracking is actually working fine?
A brief acknowledgment ("I can see why that looked concerning") tends to land better than a purely technical correction, even when the fault turns out to be a simple misunderstanding rather than an actual error.
What if the tracking number returns a completely different recipient's information?
This is rare but does happen, usually from a carrier system error or a duplicate number issue. Contact the carrier directly rather than troubleshooting further yourself — this isn't something that resolves with a corrected link.
How long should I wait before telling a customer their package might be lost?
Only after the shipment has shown no movement well past the carrier's typical window — generally at least double the expected transit time — and only after the carrier itself has confirmed there's a genuine issue rather than a delay.
Is it worth asking the customer to try tracking again before I investigate on my own?
It can help rule out a temporary glitch, but it's usually faster to verify the number and status yourself first — that way you're troubleshooting with accurate information rather than relying on a description of what the customer saw, which can leave out details that matter.
- A "tracking isn't working" complaint usually comes from one of four causes: a typo, the wrong carrier site, a pre-scan delay, or a broken link — rarely a lost shipment.
- Verify the number from your own records before assuming the customer's version is correct.
- A "label created" or "pre-shipment" status means the number is working fine — the shipment simply hasn't been scanned yet.
- Having a saved reply for each common cause dramatically speeds up resolution.
- Escalate to the carrier only once the number, link, and timing have all been ruled out as the actual issue.
