The most common other words for headquarters are head office, main office, and HQ. All three mean the place where an organization is run from. If you mean a military or emergency base, command post or command center fits better. If you mean any central base of activity, base and hub often work.
The best choice depends on meaning and context. Some alternatives describe a company’s top office. Others describe a place where orders are given, a base for a team, or the people who run an organization. Some are formal, some are informal, and some are only loosely related to “headquarters.”

Headquarters vs. Head Office vs. Home Office vs. Main Office
These four terms are often treated as the same, but small differences exist.
| Term | Typical Meaning | Notes |
| headquarters | The central place or administration of an organization, military unit, or activity | The widest term. It works for companies, armies, police, and campaigns. |
| head office | The top office of a company | Very common in British English and in banking and retail. |
| home office | The main office of a company (US); a work area at home | Can be confusing. In the UK, the Home Office is a government department. |
| main office | The principal office, large or small | The plainest choice, with no special tone. |
A useful rule: use “headquarters” when you want one word that fits many settings, and a more specific term when the context is clearly a company, a campaign, or the military.
