DWP asking for banking details on phone as part of automated questions

A colleague has mentioned that when calling DWP contact centres, amongst the automated questions you are asked are the sort code of your bank account and the last 3 digits of the account number.

Given the current vogue for fraud by unscrupulous third parties, how long before they twig that people are getting used to being asked this sort of thing by DWP and start phoning people up, pretending to be from DWP and asking for considerably more than three digits?

Is this at all wise?

ive a few additional issues with this.

1. you give info and get put through to someone who then doesn’t have it which makes me wonder what the point was
2. getting it to understand the work May in a Glaswegian accent is clearly an impossible task

It’s usually quicker getting through to an adviser if you fail the security questions.

Silver linings…
