The National Drug Code (NDC) is a universal product identifier for human drugs. Locate this 10 or 11-digit number to access precise allergen reports.
Look for the NDC printed near the barcode or the drug facts panel on the cardboard box or wrapper.

Directly on the prescription bottle or vial, the NDC is often listed at the top or bottom of the manufacturer label.

If the original packaging isn't available, the NDC code is printed on the patient information sheet from the pharmacy.
