Assigns customers to stores by closest location using a straight-line distance method.

Learn more about how Assign by Closest Location works

Usage

• You cannot undo the assignment of customers to stores in an existing field.

• Customers are assigned to the closest store location.

• Assignments are based on a straight-line Euclidean distance calculation.

• Use the Assign By Trade Area tool if you do not want to assign customers using a straight-line distance. The Assign By Trade Area tool can be used with drive-time polygons.

• If a customer is at an equal distance from two or more stores, the customer will be assigned to the first store in the attribute table.
