What is Headquarters?

Headquarters is the country of a provider's head office, shown as a country code. It hints at which jurisdiction handles your contract and where support is staffed, which is useful when a brand operates in a market it does not call home. 019 Mobile is headquartered in IL and 1&1 in DE. 100Green, 1pBroadband and 1pMobile are all based in GB, the same home market they sell in.
