Which multipack barcode should an RVM read?

For a programme that takes individual bottles or cans, check the barcode on the empty container against the programme’s accepted record. Record the outer multipack barcode separately for traceability. It identifies the retail pack and cannot establish the eligibility of the items inside it.

Why can the two codes differ?

GS1 distinguishes identifiers for managed packaging levels and pack sizes. A four-can carton can have a Global Trade Item Number (GTIN) for the retail pack, while the cans inside carry a code for the individual product. The return programme determines which code belongs in its acceptance record.

Ireland’s Re-turn technical manual, for example, calls for a barcode on each individual container in a multipack. When qualifying packaging for a different programme, use that programme’s own requirements and check the code on a physical sample from the relevant market.

How should a team qualify the return?

1. Photograph the outer packaging and a representative empty container. Record each code alongside the item it came from. Keep the original digits, including leading zeros, and use the programme’s format when looking up a code.
2. Verify the individual code, container format and market against the applicable acceptance record. If the code is absent, obscured or unmatched, record the issue and ask the programme or packaging owner to resolve it before approval.
3. Test the empty container under the installed machine’s approved procedure. Record barcode recognition, physical acceptance and the resulting programme event separately. Use the test environment and procedure agreed for the project when a payout or voucher is involved.

What should a test record look like?

Suppose a promotional four-pack has a new carton code, and the can inside still carries the same code as the previously tested can. The record would show both codes, link the previous container record, and confirm the current result on a sample from the promotional run. If the carton code is the only one available, record the individual code as missing and route the sample for review. Keep the carton code in the packaging record so the team can identify the affected batch.

Use the label-change validation guide to check changes to printing and placement, and the rejected bottle checklist to troubleshoot an unexpected result at a live return point.
