I'm not sure if this will work for your phone number, but try it and see.
It works for our USA phone numbers and I don't have a clue why it works.

I copied this years ago and can't remember where it came from.
I thought I'd share it with you all for a bit of fun...

1. Grab a calculator (You won't be able to do this one in your head)
2. Key in the first three digits of your phone number (NOT the area code)
3. Multiply by 80
4. Add 1
5. Multiply by 250
6. Add the last 4 digits of your phone number
7. Add the last 4 digits of your phone number again
8. Subtract 250
9. Divide number by 2

Do you recognize the answer?

Spooky, ain't it?
