Selector Code
The alphanumeric code that identifies a specific line item in Xactimate. Combines the trade category prefix with an item identifier to uniquely reference each piece of scope.
A selector code is the alphanumeric code that uniquely identifies a specific line item in Xactimate. It is the base reference that, combined with an activity code, makes each scope line specific and unambiguous.
How Selector Codes Work
The selector code begins with the three-letter trade category prefix. After the prefix, an item identifier narrows the reference to a specific item within that category. A complete line item combines the selector code with an activity code (like R&R for remove and replace, or RM for remove only) and a quantity. Together these pieces create a specific, priced line in the estimate.
Why Estimators Memorize Codes
Typing a selector code directly is faster than navigating through category menus. Experienced estimators know the most common codes in their trade by heart and can enter line items in seconds. Cheat sheets and training resources help new users build the same fluency. For contractors who use Xactimate daily, this efficiency compounds across hundreds of line items per week.
Codes in Supplements
When reviewing an existing estimate to write a supplement, the selector codes are the roadmap. Each code tells the reviewer exactly what item was scoped, what action was applied, and what quantity. Missing items are identified by what codes should be present but are not. Mis-scoped items are identified by codes that are present but wrong for the scope. Reading selector codes is the primary skill of a supplement specialist.
