What characters can appear in the generated code?

Uppercase letters A-Z and digits 0-9 only — no lowercase or symbols, so codes stay easy to read, type and scan on a barcode label.

Can two generated SKUs collide?

It is possible with short/few segments — use a longer segment length or more segments for a lower collision chance across a large catalog.

No — they are generated and shown locally in your browser only.
