I'd like to learn from the experts various use cases of the Check # field (NUM) in the banking register. In my view this is yet one more way to sort or tag transactions (DEP, TXFR, etc.). In reality I have never used it and for sure over 99% of my transactions are blank. I have not written an actual check in over 15 years. What are some good examples or creative ways to make the best use of this field, if any? FOMO. Thank you.
