A local number matters because it is the first thing a homeowner sees: an area code, a name if one is on file and, on many phones, a label if the number has a poor history. A number from the market you work says you are local before you do.
Koda Voice assigns local numbers for the markets a team actually serves and expects each number to carry one consistent identity. Rotating numbers to outrun a label is the opposite, and Koda's acceptable-use policy prohibits rotating or discarding calling numbers to evade labeling or blocking. A swapped number never builds a history, and history is what the reputation engines score.
