Food Lot Numbers: Supplier, Packaging and Shipment Records
A food lot number helps connect a pack to a defined batch and the records held for it. For wholesalers and importers, its value comes from the link between the code, product, supplier, quantities and movement records. A code printed on a pouch does not create that record trail by itself.
This guide explains how to read the supplier’s lot reference, keep it through receipt and dispatch, and link it to the shipment file. The same practical questions apply when evaluating Vietnamese coffee, tea or dried-fruit products for a business order.

What a Food Lot Number Identifies
Ask the producer or packer what a lot represents for the offered product. It may refer to a production or packing run under that business’s coding system. Record the exact product and supplier alongside the lot; a short code should not be treated as globally unique on its own.
GS1’s foodservice identification guidance describes the combination of a product identifier, the GTIN, and batch or lot information. The important buying distinction is between identifying the product and identifying the batch of that product.
Keep the lot number separate from the best-before, use-by or production date shown for the item. Ask how each marking is defined. If the code contains date-like digits, obtain the issuer’s explanation instead of assuming that those digits establish the production day.

Read the code as the issuer defines it
Suppliers can use numeric or alphanumeric codes. A code such as A24C05 is only an illustration: its letters and digits have the meaning assigned by its issuer. There is no single format that should be assumed for every Vietnamese manufacturer or food product.
Capture the code exactly as printed, including leading zeros and separators. Compare the retail pack, case marking and supplier record. Ask how those references relate when one shipment contains more than one lot.
Check what the barcode carries
GS1’s barcode overview distinguishes product identifiers from additional attributes such as lot numbers and dates. Do not assume that scanning any retail barcode captures all of them. Confirm the encoded fields, scanner capability and how the result enters your stock record.

Connect the Code to Supplier and Customer Records
Keep the incoming and outgoing links
At receipt, connect the product and supplier’s lot reference to the purchase order, received quantity, cases, date and storage location. At dispatch, connect the lot and quantity to the customer and delivery record. Those links help the team find where a particular batch came from, where it is held and where it was sent.
Review a reported mismatch or issue
If a customer reports a concern, collect the product, lot, date marking, pack photographs and delivery reference. Use the records to identify the stock and deliveries that need review, then involve the supplier and responsible quality team. Let that review determine the action and affected scope.
Use date information alongside the lot
Keep the relevant date marking and storage instructions in the stock record. Plan rotation around the product’s requirements and the dates actually supplied. The lot helps retrieve the record; it does not by itself prove freshness, remaining shelf life or that every destination requirement has been met.

Build a Lot Record from Receipt to Dispatch
Agree the record before shipment
Ask where the lot appears on the retail pack and cases, whether multiple lots may be supplied and which shipment documents will carry their references. Confirm the relationship between product, packing run and case markings before the goods move.
Record receipt and differences
Count and record the quantities by product and lot. Compare the delivered markings with the supplier’s information and note missing, illegible or unexpected references for clarification. Keep date markings and pack-condition observations with the same receipt record.
Preserve the link during handling
When cases are opened, goods are moved or packs are relabelled or repacked, record the link between the incoming lot and the outgoing units. Keep different lots identifiable. Agree with the responsible team how a changed pack or newly assigned code relates to the original batch.
Check that the record can be retrieved
Use a sample delivery to check whether the team can retrieve its supplier, lot, quantities, location and customer dispatches. A spreadsheet or warehouse system needs consistent entries and a defined review owner; software does not correct a missing code or broken record link automatically.
Keep the lot list with the invoice and packing information used for the shipment. Identify which references your team and supplier have agreed to include instead of assuming every document uses the same format.
