The issue is when criminals spoof the real number of a bank, government department, etc. The best advice is don't give out any information of a personal or sensitive nature to anyone calling you, insist on a reference number and say you'll call back after checking the phone number on some documentation from the organisation - or their website, although be careful because sometimes sophisticated frauds involve climbed websites. https://www.bbc.co.uk/news/business-56934517
