Frequently asked questions
- Are the codes guaranteed unique?
- They are random, so duplicates are extremely unlikely for reasonable batch sizes, but this tool does not track past codes. For strict uniqueness, check them against your database.
- Why are some letters and numbers missing?
- Ambiguous characters like 0/O and 1/I are removed so codes are easy to read aloud and type without mistakes.
- Can I add my own prefix?
- Yes. Add a prefix such as SALE or SUMMER and it is prepended to every code.
