What a tracking page is telling you, and what to do when it is not telling you anything yet.

Reading your result

What each status means

  • Info received

    info_received

    The seller has created a shipping label and registered the shipment with us. The parcel itself has not moved yet.

  • In transit

    in_transit

    The parcel is moving through the network. Each line in the history is a scan at a facility along the way.

  • Out for delivery

    out_for_delivery

    The parcel is on the vehicle bringing it to the address, usually for delivery the same day.

  • Delivered

    delivered

    The parcel was delivered. The page keeps the full history afterwards; nothing is removed.

  • Delivery exception

    exception

    A delivery attempt did not succeed. This most often clears with the next attempt.

A shipment's status only ever moves forward; it never returns to an earlier stage. These same five values appear in the tracking API, so a tracking platform shows you the same words we do.

Why the page sometimes stands still

How a shipment moves through tracking

  1. Label created

    The seller registers the shipment and an ASLTrack number is issued. It can take up to 24 hours before that number opens a page.

  2. In transit

    The parcel is scanned as it arrives at and departs from sorting facilities. Each scan becomes a dated line in the history.

  3. Out for delivery

    The parcel is loaded onto the vehicle that will deliver it.

  4. Delivered

    The status stops moving, and the history stays available.

Tracking updates when a parcel is scanned, not continuously. Between two scans — on a long leg between facilities, for example — the page can stay unchanged for a day or more. That is normal and does not mean the parcel has stopped.

Privacy

What we show, and what we don't

A tracking number is the only key to a tracking page. That means a page has to be safe to hand to anyone holding the number — so we decided early what may appear on one.

  • Tracking numbers are allocated at random, not in sequence, so one number reveals nothing about any other.
  • Lookups that find nothing are rate-limited per connection, which makes scanning the number space impractical. Successful lookups are never counted.
  • Tracking pages are excluded from search engine indexing.

Several tracking services show a full street address to anyone holding the number. We consider that a defect rather than a feature.

What a page shows

The current status, the dated history of events, and locations at city and state level.

What a page never shows

The recipient's name, the street address, the contents or value of the parcel, or who sold it.

What we do not even keep

The recipient's name and street address are not stored in the tracking system at all. Information that is not held cannot be exposed — by us, by a mistake, or by anyone else.

Troubleshooting

Can't find your number?

  • It may be too early. A shipment can take up to 24 hours to appear after the label is created. Nothing is wrong in the meantime.
  • Check the number one character at a time. Every ASLTrack number ends in a check digit, so a single mistyped or transposed character will never match — there is no "close enough".
  • The shape is fixed: ASL followed by 11 digits. Spaces and lower case are fine; anything else is not part of the number.
  • If the seller sent you a tracking link, opening that link is the surest way to reach the right shipment.
  • Told there were too many lookups? The service limits failed lookups from one connection, to make guessing at numbers impractical. Wait a few minutes and try again.
  • Still nothing after 24 hours? Email support@asltrack.com with the number and we will look it up.

Questions

Frequently asked questions

Do I need an account to track a shipment?

No. There is no sign-up and no sign-in. The tracking number is the only key, so anyone you give it to can open the page — and nobody else can.

Is ASLTrack the company delivering my parcel?

ASLTrack issues the tracking number and publishes the shipment's progress. The physical movement is carried out by the transport networks the seller uses. We do not operate vehicles or warehouses, and we would rather say so than let it be assumed.

My tracking number doesn't work. What now?

Two common reasons. A new shipment can take up to 24 hours to appear after the label is created. And every ASLTrack number ends in a check digit, so a single mistyped character will never match.

If it still does not work after 24 hours, email support@asltrack.com with the number.

Why does the page only show a city and a state?

Because that is what answers "where is my parcel?". The recipient's name and street address are not published — and not stored either, so they cannot leak from here.

The status hasn't changed for two days. Is something wrong?

Not necessarily. Tracking updates when a parcel is scanned, and there can be a long leg between two scans. If a shipment stays unchanged well past its estimated delivery date, email us with the number.

It says "Delivery exception". What should I do?

An exception means a delivery attempt did not succeed — often simply that nobody was available to receive the parcel. It usually clears with the next attempt. If it has not changed in a couple of days, contact the seller you bought from: they are the party who can act on the shipment.

It says delivered, but I don't have the parcel.

Check with anyone else at the address and around the entrance first. If it still has not turned up, contact the seller you bought from — the order is between you and them, and they are the party who can replace or refund it.

Can I get an email or a text when it arrives?

Not at the moment. There is no notification service, and we would rather say so than collect an address for one that does not exist. Keep the tracking link instead — it always shows the latest we have.

Can I see who sent the parcel?

No. A tracking page shows the shipment's movement, not the order behind it. Your order confirmation from the seller is where that belongs.

Integration

For tracking platforms and sellers

For tracking platforms

One read-only endpoint returns the same status and history this page shows.

GET https://asltrack.com/api/v1/track/ASL48271930652

No authentication — a tracking number is the only credential, as with any carrier. Responses are JSON, timestamps are ISO 8601 in UTC, events come newest first, and the five status values above are the entire vocabulary. Numbers match ^ASL[0-9]{11}$ and carry a Luhn check digit, so a malformed number can be rejected before a call is made. Cross-origin requests are allowed.

For sellers

Shipments registered with us receive an ASLTrack number in a single self-validating format, and the buyer can open the tracking page with no account and no sign-in. The same information is available over the API.

support@asltrack.com

ASLTrack is a visibility layer: we issue tracking numbers and publish delivery progress so the person waiting for a parcel can see where it is. The physical movement of each shipment is carried out by the transport networks our merchants use. We do not operate vehicles or warehouses, and we say so plainly here rather than leave it to be assumed.

Questions about the order itself — a refund, a return, a wrong item — belong with the seller you bought from.
