CubeSmart
U.S. Location Dataset // 1,578

1,576 CubeSmart self-storage locations across the United States, with street address, phone, coordinates and the facility attributes published for each site. This is the third of the big three public operators, with a footprint concentrated in dense urban markets. Buyers use single-operator footprints for competitive mapping, for site selection against an existing network, and for vendor prospecting where the operator is the account. Refreshed weekly from the operator's own locator, so closures and new openings appear as they happen rather than months later.

All 1,578 records, as published — the complete set rather than a sample. That matters most for coverage and gap questions: put together the same list from partial searches and every location you miss reads as a gap that is not there, so the answer is wrong rather than merely late. Assembling the U.S.-wide coverage by hand also means one query per area against sources that cap what they return per search.
