"Other locations" or "secondary locations" works for me.
Student or Learner
Let's assume that a particular store has several shops/locations within a city: there are its main location (the biggest shop) and the other locations (smaller): is "secondary locations" the best way to describe these other locations?
I heard of the main store and branches of a chain store.
But I have not heard of main location and secondary location in relation to stores.
Secondary location is a term used in real estate which is defined as:
secondary location - a location that is not the best location. In a commercial sense, it is the location farthest from the anchor or prime tenants, parking, or general flow of vehicular or pedestrian traffic.
