What is a batch number?
November 12, 2026
A batch number (also called a lot number) is a code given to a group of products made or received together. It lets a retailer trace exactly which units came from the same production run, so they can be found quickly in a recall, expiry check or quality complaint.
Why it matters for online retailers
If a supplier recalls a product, you need to know which batch is affected, where those units are in your warehouse and which customers received them. Without batch numbers you may have to pull every unit of the SKU instead of one batch.
Batch numbers are essential for food, supplements, cosmetics, medicines and anything else with an expiry or best-before date.
Batch number vs SKU vs serial number
- SKU: identifies the product, for example a 500g tub of protein powder in chocolate flavour.
- Batch number: identifies a group of those tubs made or received together.
- Serial number: identifies one individual unit.
How batch tracking works
- Record the batch number when stock is booked in.
- Keep batches in known locations so they can be found.
- Pick the right batch for each order, usually the oldest or shortest-dated first.
- Record which batch went to which customer.

Frequently asked questions
Is a batch number the same as a lot number?
Yes. The two terms are used interchangeably.
Where do I find a product's batch number?
It is usually printed on the packaging, often near the barcode or the expiry date, and on the supplier's delivery paperwork.
Do I need batch tracking?
If you sell products with expiry dates or that could be recalled, such as food, supplements, cosmetics or medicines, batch tracking is strongly recommended and may be required by your suppliers or regulators.
