Totally agree, sequence check is the best option!

Cyclic redundancy check? Really? That seems off.

I think edit check could work too, but not as effective.

I don't recall much about reasonless checks, but they sound like they wouldn't be effective for this scenario.

I feel like cyclic redundancy checks are more about error detection in data transmission, not really for preventing duplicates.

I'm not entirely sure, but I remember practicing with edit checks for data validation. Would that help with duplicates?

I think a sequence check might be the best option since it can help ensure that each voucher is unique and in order.

The calendar delivery deadline and the need for a recruitment campaign within 12 months seem like the most relevant timescale considerations here. I'll go with those.
