Where our tracking records come from

This is the most important page on our site, so we have tried to write it plainly.

What you are buying

Every record in our inventory is imported in bulk from a FedEx tracking feed. Each one arrives in an ingestion batch that we keep a permanent reference to, so any number you buy can be traced back to when and how it entered our system.

What you get is a real FedEx tracking number, together with everything the feed knew about it:

• the full route — origin city and state, destination city and state;
• the service it travelled on (FedEx Home Delivery, Priority Overnight, SmartPost and so on);
• weight, dimensions and piece count;
• the ship date, the estimated delivery date and, if it arrived, the exact delivery timestamp;
• the scan count and the carrier's own status line, stored verbatim.

What we will not do

We do not generate numbers that merely match a carrier format. It would be trivial to write — FedEx's numbering scheme is documented and a check digit is arithmetic. We do not do it, for three reasons.

It would not be the product we are describing. A format-valid string is not a tracking record; it is a string. It does not exist in FedEx's network, it has no route, no weight, no scan history. Selling one as a tracking number would be a lie of a fairly direct kind.

It would break the moment anyone checked. A number that resolves to nothing is worse than no number at all, because it looks like a deliberate attempt to mislead.

And it would make our own audit trail meaningless. The point of recording where a record came from is that it can be inspected later. Provenance for a fabricated value is theatre.

What "never sold before" actually means

When you tick that box, you are filtering for records that have never been sold to any other customer of ours. We can prove that: buying a record marks it as yours with a database constraint that makes a second active sale impossible, not merely discouraged.

What we cannot tell you is whether an Amazon or Walmart seller has used a given number. We have no access to marketplace seller data. Nobody selling tracking numbers does. If a competitor tells you they verify against Amazon, ask them how — the honest answer is that they are guessing.

So we label the filter for what it is, and no more.

What a record does and does not tell you

A record we sell you is a real FedEx tracking number describing a real shipment. What it is not is a description of the parcel you are sending. Those are different claims, and services in this category routinely blur them.

Each record also carries an observation time — when the feed last saw a status for it. Carrier status data is not real-time and we will not pretend it is. We show you the timestamp so you can judge freshness yourself.

What this means for how you use them

You are responsible for how you use these records. Marketplaces set their own seller rules, and those rules generally assume that tracking you upload corresponds to a shipment you actually sent. Using a record that does not can breach them.

Our Acceptable Use Policy prohibits using our service to defraud a buyer, to misrepresent a shipment, or to evade a platform's verification. We suspend accounts that do. If you are unsure whether your use case falls inside those bounds, ask us before you buy — we would rather have that conversation early than afterwards.

Other carriers

FedEx is what we hold today. UPS, USPS, DHL, TNT, Evri, Yodel, DPD, Canada Post, LaPoste, GLS and Royal Mail are listed on the coverage page as coming soon. They become selectable when we actually hold inventory for them — not before, and never as a filter that would return nothing.
