The lot number on a cannabis label is the batch code that identifies exactly which production run your product came from — the harvest, the extraction or infusion date, and the specific sample that went to the lab. Reading it correctly lets you trace a package back to its test results, compare one run against another, and flag a problem fast if something seems off. Here is what the number means and how to use it.

Key features of a lot number and what it does for you:
- Batch-level traceability: links your package to one specific production run, not to an entire brand.
- Printed on the package near the net weight, the potency panel, or the state compliance symbol.
- Ties directly to a certificate of analysis (COA) covering cannabinoids, terpenes, and contaminant screening.
- Mirrors the seed-to-sale tracking tag that licensed cultivators and manufacturers maintain.
- Stays identical across every unit in the batch, unlike the unique package or item code.
- Lets you compare two packages of the same strain from different production runs.
- Gives a dispensary or delivery team exactly what they need to check a batch during a recall.
Lot numbers usually appear as a short alphanumeric string — letters, digits, and often a date code — and state rules generally require them to be printed legibly rather than handwritten. Formats differ by producer: some lead with a year and month marking harvest or production, others use a sequential run code. Look on the back or bottom panel, next to the net weight, potency, and required warnings. Keep the packaging; the lot number is what you will be asked for.

Why Do Dispensaries Ask for the Lot Number?
Because it pinpoints a single batch. With it, a retailer can verify test results, check whether your product is part of a recall, and handle a quality issue without guessing which run you bought.
Is the Lot Number the Same as the Batch Number?
Yes — the two terms are used interchangeably on cannabis labels. It is not the same as the unique package or item ID, which is specific to your individual unit.
How Do I Use the Lot Number to Check Test Results?
Give the number to your retailer or scan the QR code on the package to pull the certificate of analysis for that run. The COA lists potency, terpenes, and contaminant screening for that specific batch.
