Where is Iron Mountain headquartered?

Iron Mountain's headquarters is in Portsmouth, NH. The main address used for this profile is 85 New Hampshire Avenue, Suite 150, Portsmouth, NH 03801, based on public company and investor materials.

For executive outreach, the HQ is the best anchor for finance, legal, investor relations, corporate IT, procurement, and leadership functions. Asset, property, construction, leasing, or field operations may sit closer to regional markets.

The public footprint includes Portsmouth, NH - HQ; Boston, MA - corporate presence; Global records facilities; Global data center markets. Some locations are corporate or regional offices, while others are operating markets, field offices, properties, communities, sites, stores, or divisions.

That distinction matters: a property-heavy company may make corporate technology decisions centrally but still require field validation in representative markets before broader deployment.

Territory planning should start with the HQ for executive alignment and then branch into the highest-value operating markets. For real estate and homebuilding companies, regional leaders often control adoption, budget influence, and practical rollout constraints.

ABM, field events, and executive briefings should map to where the buyers sit: corporate finance and IT near HQ, market operations near regional offices, and property or community users in local markets.
