Joblessness dropped to 4.7%, down from 4.8% a month earlier and from 5.1% in January 2016, according to the Office for National Statistics.
The last time unemployment was this low was a period of strong economic growth in 2004 and 2005, and joblessness has not been lower since the mid-1970's.
Employment rose to a new record high of 31.85m with an extra 92,000 jobs created over the three-month period, while unemployment fell by 32,000 to 1.58m.
Minister for Employment, Damian Hinds said:
"I’m delighted by another set of record-breaking figures showing more people in work than ever before and unemployment falling to its lowest in 12 years.
Employment is up, wages are up and there are more people working full time. This is good news for hardworking families across the UK as we continue to build a country that works for everyone.
Today’s figures also show:But we have more to do, which is why we’re pressing ahead with our welfare reforms to ensure that it always pays to be in work."
