Telephone numbers in Europe

Telephone numbers in Europe are managed by the national telecommunications authorities of each country.

Calls between member states would no longer require the international access code 00.

This proposal would have required states such as Germany, the United Kingdom, Denmark and others, whose country codes began with the digit '4', to return these to the International Telecommunication Union.

A Green Paper on the proposal was published, but the disruption and inconvenience of the change was deemed to outweigh any advantages.

Another disadvantage would be that people wanting to call France (e.g. Southeast France using +33 4...) using an old number would connect another country like Spain, or people wanting to call Spain (e.g. +34 9...) would end up in e.g. Germany if they use an old number.
