Beast of the Number: Parsing the Feral Phone
Just another 0.02€:
In Denmark there is no areacode. Phone numbers are just 8-digit numbers with a possible extension (no standard for that, format etc depends on the local switchboard). The number is traditionally formatted as dd dd dd dd, but even that has begun to vary: some people use 2 groups of 3 digits and a 2 digit group, others 2 groups of 4 digits!
Earlier you could figure out which phonecentral the number was attached to, but following (EU instigated?) rulechanges you can take your number with you when you move from one part of the country to another. Thus there is no areacode, or all of Denmark (including cellular phones!) is in the same area.
Things do vary.
