Use the full series and unique code exactly as printed. Both values are required and checked as one combination.
Verification is case-insensitive. Spaces and hyphens inside the unique code are normalized.
A valid code is not silently invalidated after one use. Instead, the system reports the number and timing of checks so an unexpected previous verification can be investigated.
