Joshua: If you have a policy with them, then look up the number from your own records and give them a call. They do sometimes need additional details like this but… they will not ask for this outright and you should not mail in the details or follow any numbers or links they send like this. To be safe they might indeed need something but dont use the letter for reference. look up the number from something you already have and give them a call if its genuine they will tell you if not they can help you with reporting it.
Not necessarily a scam. But I would never provide a bank account number to anyone for direct debit.
Insurance companies will run a credit check on you before they decide to insure you and also how much they will charge you.
If you did not initiate this correspondence with the insurance company, it is possibly a scam
Phone the advertised number for the insurance company to confirm. NEVER follow links or open attachments in these messages.
Assume a scam, until proven otherwise.
What are the details of this "letter"? (Or is it an e-mail?)
It depends on the context but usually if a payment is coming to you, you would have had to make a claim first.
its a scam
