In British English negative questions with the verb have (when it's a lexical verb and not an auxiliary) can be formed in two ways. Is there any difference between them?
Type 1
- Haven't I got your number?
- Haven't you got her number?
- Hasn't he got your number?
- Haven't we got her number?
- Haven't they got our number?
Type 2
- Don't I have your number?
- Don't you have her number?
- Doesn't he have your number?
- Don't we have her number?
- Don't they have our number?
