## Questions

### How many Costco warehouses are in this dataset?

548 deduplicated warehouse locations across 44 US states. Every record has verified GPS coordinates and street address.

### What data fields are included?

Store name, full street address, city, state, ZIP code, phone number, latitude/longitude GPS coordinates, and website URL. Standard CSV format ready for import.

### How is this data compiled?

Costco's own store locator is aggressively rate-limited and protected by bot defenses. We aggregate from multiple public POI sources and apply a 50-meter spheroid-distance dedup to produce one record per physical warehouse. Cross-checked against published Costco store counts.

### How often is the Costco dataset updated?

File built on September 20, 2026. It is not on an automatic refresh schedule, so check the build date above before you buy.

### We sell premium consumer goods. How useful is a Costco dataset for us?

Costco members skew high-income and make large basket purchases — it is one of the strongest premium-CPG distribution channels in the US. Mapping the 549 warehouses by state and metro area shows you the highest-value retail touchpoints for premium brands, and the GPS coordinates let you run catchment analysis against census income data.
