Your phone number will usually need to correspond to your country of residence to allow us to verify your account. There are some exceptions to this:
If your country of residence is the US or Canada, you will need to provide a phone number from either the US or Canada
If your country of residence is the UK or Ireland, you will need to provide a phone number from the UK or Ireland
If your country of residence is anywhere else in our accepted country list, you will need to provide a phone number from the same continent as your country of residence, and the number needs to be from a country which is also on our accepted country list
You can read more about verifying your phone number, and your account in general, here.
