The guest check number can be between 1 and 9999 (a four-digit number). Generally check numbers start in numeric order. If a workstation operator begins check number 1007, the next check number for the revenue center is 1008.
If the property has multiple revenue centers and wants to keep unique check numbers for each revenue center, you can assign an exclusive range or check numbers per revenue center. For example, Revenue Center 1 could have checks from 1000 to 1999 and Revenue Center 2 could have checks from 2000 to 2999.
