This might require a huge shake-up of the current mobile phone numbers, but...
You give everyone the option of having a phone number that has their birthday as the last 4 digits [so I might have 07832 430705], that way anyone who know me would be able to know just by looking at it that they should send cards on the seventh of may.
The other numbers, that don't correspond to valid dates, could be used by business or anyone who didn't want their birthday displayed...

It's rephrased... and it was meant to be 4, but started as 6, and I think I got thoughly mixed up, it's still to early in the morning...

Since lots of people share the same birthday, will there be enough birthday phone numbers to go round?

hazel couldn't you just use your current number and just add the new 4 digits. and for companys and just dont add the new numbers to the end its that simple +
