You cannot create a Page for just a city or county/region. However, you can publish to people in a particular city/county/region such as London, for example, by publishing from the UK Page and targeting users in London.

Global Pages work at a country and language level. The first level of targeting is done on a country level. Then, if you wish, you can add an additional layer of targeting by language. For example, for a country such as Canada where people speak both English and French, you can:

• Create a market Page for Canada and add language targeting to each post. To publish something in a particular city or county/region, we'd recommend publishing from the country market Page and targeting users in that specific city or county/region.
• Create two Pages for one country. One for people who speak one language and another Page for those who speak another language. Depending on the language people set up their Facebook in, they will be redirected to one of the market Pages in the language or to the Default Page.
• Create a Page for Canada with English targeting and redirect people who speak other languages to another market Page. E.g. redirect people who speak French to the France Page or redirect people who speak Spanish to the Mexico Page etc. There are many combinations possible.
