New agreements setting out what jobseekers will do to find work in return for their benefits have now been rolled out across Britain, covering 635,000 claimants, according to the latest data.
The Department for Work and Pensions (DWP) said the Claimant Commitment had been successfully introduced in all jobcentres, with people agreeing the steps they will take each week to find a job.
Measures include registering and looking for work through the Universal Jobmatch service or via a recruitment agency.
Jobseekers risk facing benefit sanctions if they refuse to co-operate with the contract.
Welfare Reform Minister Lord Freud said: "With Universal Credit, we are creating a modern and sustainable welfare system that is fit for the 21st century - one that supports people when they need it and helps them become independent.
"The Claimant Commitment redefines the relationship between jobseekers and the state. Claimants receive greater support to get into work from their work coach and we expect them to do all they can to find a job as quickly as possible as part of the deal for receiving their benefit.
"Staff have told me it has strengthened their ability to support people into work at the earliest opportunity."
