All geographic numbers had to be dialed in the ten-digit format, even for local calls. The international access code also changed from 19 to 00 . Following liberalisation in 1998, subscribers could access different carriers by replacing the '0' (omitted from numbers when called from outside France) with another digit. For example Cegetel required subscribers to dial '7', e.g:Paris 71 xx xx xx xx, instead of 01 xx xx xx xx. Similarly, the international access code using Cegetel would be '70', instead of '00'.
