"This is done as an anti-scam and anti-fraud initiative, so that you can always get through to a legitimate number without having to look it up," Martin said. "Just remember '159'. It's done so you can call them both generally but most especially if you get a call from your bank [and] you're not sure it's really them..."

In a later post, the money expert responded to concerns that calling 159 immediately after receiving a potential scam call could mean scammers have 'spoofed' the line. This is where criminals manipulate the caller ID to disguise their identity or make the call appear to be from a trusted source.

"Yes, while it is rare, it happens so that's sensible, or [you can] call from another phone, or call a friend first so you know the line's not spoofed," Martin added. "Scammers are most likely to be spoofing your bank, not the 159 number which asks which bank you're calling. So if it doesn't do that you'd know."
