Which range is used for daily receipt numbers in the example?

• A. 001-9999
• B. 000-999
• C. 010-999
• D. 001-999

Answer: (D)

Daily receipt numbers are usually a fixed-length, three-digit sequence with leading zeros. This keeps every receipt code the same width, which makes data entry, validation, sorting, and daily resetting straightforward. The best range uses the full three-digit window from the smallest nonzero code up to the largest three-digit code, giving a clean 001 through 999. This avoids ambiguity with an all-zero code (which can be treated as “none” or invalid) and stays within the intended three-digit format.

The other options don't fit this approach: one would require four digits, breaking the fixed-width format; another would include 000, which can cause confusion or be misinterpreted as a non-issued receipt; another would start at 010, skipping 001–009 and wasting available codes.
