Lot Numbers for Small Food and Product Businesses

A useful lot code connects the package to an internal record.

A lot number should let your team identify when and where a product was made, which formula revision was used, which ingredient lots were consumed, how much was produced, and where finished units went.

Build the calculation from reliable inputs

Keep the printed code short and scanner-friendly. Store the meaning in your system rather than encoding sensitive details into a complicated public string. Date-based sequences can work when same-day batches remain distinguishable.

Turn the answer into a repeatable process

Test uniqueness, label readability, manual entry, corrections, rework, split lots, and returns. During a mock recall, start with one finished code and prove you can trace backward to supplier receipts and forward to affected orders.
