Why do phone numbers start with the number 0?

Answer 1

In the uk national numbers are prefixed with an area code which itself begins with a zero. So a 'fully qualified' telephone number here in the uk, does in fact start with a zero.

As to why this is, could be because historically before we had STD (Subscriber Trunk Dialling - Where you pick up a phone and dial a Trunk or national number directly) you would have had to have dialled the operator - '0'
for her to put you through.

Answer 2

Phone numbers in the UK start with 0. Maybe in other countries too. But when you phone UK number from abroad, you delete the 0. I have not found a US area code or phone number that beings with 0.

Perhaps the UK numbers start with 0 just because no other numbers begin with 0.
