This is not a number: 123456
This is not a number, but an address 123 456
My parameters are 90/60/90 - 120/150/120 - not a phone number
I am cheeky and I use letter 0 instead of zero 604_213_0293 Or I use | symbol
and also 604_2|3_0293 may happen
The most classical Canadian number is +1(604)123-4567 hi hi
Dashes can be different 123-456–7890
And looks like phone +I(800)-2l4-15O but contain combination with letter
