International Phone Jack Types
Analogue telephone connectors vary far less than power plugs — RJ-11 dominates almost everywhere — but a handful of national standards (BT 431A in the UK, TAE in Germany, local connectors in older European installations) still appear and will block modem, fax, or land-line use without the right adapter.

Each standard has a dedicated reference page listing countries that use it, the underlying telecom standard, and matching RJ-11 conversion adapters.
