Frequently Asked Questions
How do I design the format?
Prefix (product line) + segments (batch/year) + checksum character: ABC-2026-XXXX-C catches typos at entry. Keep total under 25 characters for labels.
Checksums worth it?
Yes for manual entry — one check digit catches ~90% of transcription errors. Barcoded flows can skip them.
Uniqueness guaranteed?
Random segments collide rarely at scale; sequential plus database-unique constraint guarantees. Choose per volume.
Do serial batches leave the browser?
No — generation runs locally in your browser. Nothing leaves your device.
