Cartons, numbers and SKUs: prepare identification you can check

Define what each reference identifies

Separate the order reference, product SKU and carton identifier. A SKU may appear in several cartons, and a carton may hold several SKUs. Agree with the supplier what each field means and which unit is counted: pieces, pairs or sets, as applicable to your order.

For example, FedEx documentation for multiple-piece shipments distinguishes master tracking and package labels. That is its system: ask your operator how its references connect to your internal identifiers without replacing the labels it requires.

Choose a scheme that does not repeat in your register

You can combine an order reference with a carton identifier and use it consistently in photographs and files. For several suppliers, add a distinguishing reference or agree on a shared register so two different cartons do not receive the same identifier.

Before using the scheme, share a text example with the supplier and recipient. Confirm who prepares the marks, who checks them against the contents list and who authorizes changes. Ask for unclear details to be raised before they are used.

A fictional example with a mixed-SKU carton

All codes and quantities in this table are fictional. DEMO-P7 identifies the order, while C01, C02 and C03 distinguish three cartons; SKU-A and SKU-B represent products. The counting unit is the piece. This is not an official format or a tracking number.

Scroll the table sideways to see all columns.

Check cartons and products separately

In this example, counting three identifiers checks the carton count. Adding rows by SKU checks each product quantity. Carton C02 is counted once as a carton even though it contains two product references.

Ask the supplier to confirm the final contents record and provide photographs that connect each mark to its carton. If another file shows a different quantity, identify which is provisional and request a correction before using it to coordinate delivery. If counts use different units, resolve the unit definition before combining supplier totals in one record.

Record what changes when a carton is split

Suppose the supplier divides fictional carton C02 into two. They could retire C02 from the active list and assign C04 to its five pieces of SKU-A and C05 to its seven pieces of SKU-B. The final register would have four cartons, with unchanged product totals.

Keep the connection between the retired identifier and the new ones. Update contents, photos and carton count, and communicate which version replaces the previous one. Also request confirmation of any logistics details affected by the new packaging.

Agree how the marks will be used before dispatch

Keep the dated list, an example of the agreed marks and the person approving the correspondence. These references organize contents; they do not replace applicable legal or dangerous goods labels or carrier instructions.

For an MX Pacific Express transport inquiry, share carton count, weights, measurements, product and destination with the final register. Confirm any task you need from the supplier or operator separately and establish who will perform it.
