A mobile phone number, 555-55555, was recently sold in Kuwait for KD210,000 (~USD745,000). The international code for Kuwait is 965 btw; give the rich folk a call whenever you are bored… if you could afford the long distant charges lol.
It’s not the world record for most expensive phone number though… the number 666-6666 was sold in Qatar for a million Qatari Riyals, or about 2.75 million US Dollars in 2006 during a charity auction.
On side note… Saudi Arabia is officially going to build the new world’s tallest building (more details later). The current world’s tallest, UAE’s Burj Khalifa, is unsurprisingly located in the oil-rich region as well.
