Number in the "box" on SquareD breaker

[chrisA]

Hi everyone. I'm updating some garage wiring as part of a new workshop and I am adding a few new circuits. I was curious what the 61 vs 62 is in the little box on a SquareD Homeline 20 amp breaker. I picked up some new breakers for some extra outlets, and didn't notice until I got home that the new big box store ones say 61 in the little box but the two currently in the subpanel say 62. I know what everything else on there denotes but I've tried to research it but can't find anything on the 61vs62 so any help is greatly appreciated!

breaker example:

Square D Homeline 20 Amp Single-Pole Circuit Breaker(HOM120CP) HOM120CP - The Home Depot

The Square D by Schneider Electric Homeline 20 Amp One-Pole Circuit Breaker is used for overload and short-circuit protection of your electrical system. This breaker is compatible with Homeline load centers

My guess would be the plant number where the breaker was made.
