Direct answer: Start with the exact product name on the front of the sealed box. “FreeStyle Libre 3 Plus,” “FreeStyle Libre 3,” “FreeStyle Libre 2 Plus,” and “FreeStyle Libre 2” are different products. Then confirm the package identifier, expiration date, and any NFR, sample, DME, or institutional wording on the side panel.
Identify the product in three passes
- Front panel: record the full model name, including “Plus.”
- Side or back panel: record the NDC, product/catalog number, barcode, expiration, and lot.
- Distribution wording: look for NFR, sample, institutional, pharmacy, or DME labels.
| Front-panel wording | Key distinction | Common mistake |
|---|---|---|
| Libre 3 Plus | Plus model; current U.S. materials describe up to 15-day wear | Selecting Libre 3 |
| Libre 3 | Earlier 14-day Libre 3 sensor | Assuming all Libre 3 boxes are Plus |
| Libre 2 Plus | Plus version in the Libre 2 family | Selecting Libre 2 |
| Libre 2 | Standard Libre 2 product | Using reader information for sensor model |
| 14 Day | Older FreeStyle Libre 14 Day family | Calling it Libre 2 |
| Reader | Handheld reader, not a sensor | Entering reader as one sensor |
Where to look for product identifiers
After confirming the front-panel name, rotate the box and find the panel containing the barcode, lot, expiration, and product identifiers. Depending on the package, you may see an NDC-format number, catalog number, product number, or GTIN. Copy the label exactly rather than relying on memory.
Retail, NFR, sample, and DME wording
Two boxes with the same sensor name can have different distribution restrictions. “NFR” usually means not for resale. A free-trial or sample package may also be ineligible. DME and pharmacy versions may differ in packaging and market value. Photograph all distribution wording before requesting an estimate.
Reader versus sensor
A reader is an electronic device used to display glucose information. A sensor is the wearable component. The reader box may share the FreeStyle Libre brand but will say “reader” or show a device image. Quote readers and sensors separately.
Expiration and quantity
Record the expiration from every box. Do not assume all boxes in a stack share the same date. Count sealed retail boxes, then note how many sensors are included per box if the package states a count.
