How to spot edited numbers in a shipping notice

A shipping notice says a package is arriving today, but the tracking number, delivery date, or amount due does not look right. A small change can be an honest correction, a copying mistake, or a warning that the notice has been altered.

Compare the notice with a version you trust before paying a fee, changing a delivery, or sharing personal details. TooLab's Text Compare can show text that differs between two copies, so you can focus on the numbers that changed.

Compare the two shipping notices

1. Open Text Compare. Get the notice you want to check and a trusted copy, such as the original order confirmation or a notice opened from your carrier's official app.
2. Copy the text from the first notice into one side of the comparison and the other version into the other side. If a notice is a scan or screenshot, copy its readable text carefully or type the important lines. Check each digit against the image because text recognition can mistake similar characters such as 0 and O.
3. Compare the two texts. Review every highlighted difference, not just the first one. Search for labels such as tracking number, delivery date, package count, weight, dimensions, declared value, and amount due.
4. Write down each changed value and its surrounding label. Check the same detail in the carrier's official tracking page or your order account before you take action.

Keep the notices in their original form while you compare them. If one is an email, preserve the sender and subject details. If it is a PDF, keep the original file as well as the text you copied. A text comparison can find differences in the words and numbers, but it does not prove who sent a notice.

What the differences mean

A tracking number changed

A different tracking number may mean the shipment was split, relabeled, or handed to another carrier. It may also mean the notice points to a different package. Do not assume the new number belongs to your order just because the message uses your name. Check your order account or enter the number on the carrier's official website yourself.

A date or delivery window changed

Carriers can update estimated delivery dates as a package moves. A changed date alone is not proof of tampering. Compare it with the tracking history, and check whether the notice asks you to pay or provide information to receive the package. Treat an unexpected payment request as a separate reason to verify the message.

The amount due, declared value, or shipping charge changed

These numbers can affect what you pay or what is recorded for a shipment. Compare the changed amount with your order receipt and the carrier's official tracking details. Do not use a payment link from a notice you are unsure about. Go to the carrier's site or app independently, or contact the seller through the contact information in your order.

The package count, weight, or dimensions changed

A seller may split an order into several packages, and a carrier may record a different measured weight. Check whether the notice refers to the whole order or one parcel. If a quantity or package count does not fit the goods you ordered, ask the seller to confirm the shipment before accepting a change.

No differences appear

The two text copies match, but that does not confirm the notice is genuine. A fraudulent message can copy the wording and numbers from a real shipment. Check the sender, links, and requests separately, and verify tracking through an official route.

What to do if a number changed

1. Verify the source. Open the order account or carrier app using a saved bookmark or by typing the known address yourself. Do not follow a link or phone number from a notice you are checking.
2. Check the number in context. A tracking ID, fee, quantity, and delivery date mean different things. Read the label beside the changed value and compare the complete line, not just the digits.
3. Ask the seller or carrier to confirm it. Use contact details from your order receipt or the carrier's official site. Give them the order or tracking information, but do not send passwords, one-time codes, or full payment details in response to an unexpected message.
4. Save both versions. Keep the original notice and the comparison results if you need to report a suspicious change. Avoid editing the only copy, since the original may help support staff investigate.

Why a comparison can be misleading

Text comparison checks what is written, not whether the information is true. A legitimate notice can differ because a carrier corrected an address, added a package, or revised an estimate. Conversely, an altered notice can match an older version if both copies came from the same source.

Formatting can also make a harmless change look important. A date may be written as 04/05 in one version and April 5 in another. Spaces, line breaks, punctuation, and labels may shift where the differences appear. Always read the changed text around a number, and confirm ambiguous dates using the full month name and year.

If you copied text from a picture or scanned document, check each critical digit against the image. A transcription or OCR error is not evidence that somebody edited the notice. Text Compare helps you find what differs, then the carrier or seller can confirm which version is accurate.
