Re: Number length, was Goodbye to copper? [Telecom]

Converting currency is probably easier. There's no hardware involved,

Converting currency involves much more hardware than converting phone number lengths. Think about all the vending machines that need to accept the new coins. In the past few years, here in Greece we had to go through both. From local numbers of 7, 6 or 5 digits we went to a country-wide system where all numbers were dialed as 10 digits. This means that for most area code they went from 5 to 10 digit dialing.

Going back to telecom, the introduction of the euro meant that the last payphones that accepted coins were withdrawn.
