Other than that, all French phone numbers will change this Friday 18th
at 23:00 CET. The prefixes to the old 8-digit numbers will change.
Let x be 1 for the Paris region, 2 for the top left of France &c like this:
2 3
1
5 4
The new prefixes are (+33)x from abroad and 0x from within France.
For instance to call me at home:
(+33) 1 4626 5359 from abroad
01 4626 5359 from France
Uh, that's all.
