Official English shows an undue preference for require over its synonyms, perhaps from a mistaken feeling that want is too colloquial.
Please state if you require this amount paid in full to meet your immediate requirements. (Please say whether you would like this amount paid in full to meet your immediate requirements.)
I trust this will give you the information you require. (I trust this will give you the information you want.)
Require should not be used as an intransitive verb in the sense of need as it is in:
You do not require to do any stamping unless you wish, (you need not) and
Special arrangements require to be worked out in the light of local circumstances (special arrangements will have).
