The NDC uniquely identifies a particular manufacturer, drug-strength, and packaging combination. The NDC is often shown on your prescription bottle as an 11-digit code (see the charts below) or could be formatted as 00000-0000-00 where the first set of numbers identifies the manufacturer, the second set of number identifies the drug and strength, and the third set of numbers identifies the packaging.
