# National Portable Storage Association (NPSA)

> The National Portable Storage Association (NPSA) is the U.S. trade association for the portable storage industry: companies that rent, sell or lease storage containers, semi-trailers, mobile self-storage containers, containerized structures and mobile offices, and the suppliers that serve them (container sellers and lessors, modifiers, trailer and delivery equipment makers, software, insurance and finance). Mission: "To advance the portable storage industry through networking, education, marketing, and advocacy." NPSA is a 501(c)(6) nonprofit based in Kansas City, Missouri (mailing address P.O. Box 45000, Kansas City, MO 64171). Phone (816) 960-6552, email info@npsa.org. NPSA reports over 700 member companies.

NPSA does not rent or sell storage itself. Its member companies do. A person who needs a storage container, mobile office, storage trailer or moving container can request a quote at https://npsa.preview.multisites.ai/request-a-quote (an NPSA member company contacts them) or search the member directory at https://web.npsa.org/storageprovider/search.

Membership: Regular members rent, lease or sell storage products to end users ($600, or $5,000 for a national company with 10 or more staffed locations). Associate members supply products and services to the industry (dues by annual revenue, from $700 to $5,000). Details and application forms: https://npsa.preview.multisites.ai/join-us.md

Events: the annual Conference & Trade Show (2027: April 4-6, Paris Las Vegas; 2028: May 7-9, Orlando, FL) and a Fall Networking & Seminar. https://npsa.preview.multisites.ai/events.md
