No one was exempt from the changes being made to the French phone system.

So, no matter if you lived in Paris or Provence, you had to get used to dialling an eight-digit phone number.

"After five years and $1 billion of rethinking, reorganizing and rewiring, every French telephone number now has eight digits instead of seven," said the CBC's Don Murray, reporting from Paris on the changes being made.

The entire country switched to the new system on the same day — Oct. 25, 1985.

The French phone company had indicated "the change will add millions of new numbers" and would deal with a pending problem in Paris, which had nearly run out of seven-digit phone numbers.

A weeks-long advertising campaign had sought to educate the public on the coming changes.

The switch to the new system had been made on a Friday, giving the phone company some time to prepare for the inevitable problems that would occur at the start of the next workweek.

"It's then that the phone company is hoping and praying that 50 million French phone users can't be wrong — all at once," Murray said.
