Why people look this up

Using SIC 4225 to build a warehouse calling list

SIC 4225 is a useful first filter when you want businesses whose primary activity is general warehousing or storage. From there, employee count, annual revenue, geography, and NAICS help separate larger warehouse operators from self-storage businesses.

Common combinations buyers use include SIC 4225 plus employee count for material-handling, racking, and forklift suppliers; SIC 4225 plus city or county for janitorial, security, and facility-service vendors; and SIC 4225 plus NAICS 531130 for insurance or business-service companies targeting self-storage operators.

Warehouse records are generally more stable than fast-turnover retail files

Physical warehouse and self-storage locations can stay in place for long periods, but operators still open, close, relocate, or change names. Our US business data is refreshed quarterly, Canada is refreshed annually, and we estimate roughly 90% accuracy on business records. Check refresh timing before using a large file for outreach.
