Only 70 of the nation's 450 bureaux are taking part in the Citizens Advice Week campaign, which finishes this weekend.
But Simon Bottery, director of communications at Citizens Advice, said the umbrella organisation was not trying to "build some national model" and that individual bureaux have to do what is right for them.
Although some of the bureaux, each of which is a charity in its own right, already do street collections, this is the first time branches have banded together for a national drive to increase public awareness while raising funds.
Most of the collectors are CAB-trained volunteers who will also be handing out leaflets in a bid to dispel the myth that the bureaux are statutory organisations.
A typical bureau gets half its income from local authorities. According to Bottery, however, the street collections are part of a broader plan to diversify funding for the organisations.
As well as the national street campaign, the organisation will be looking to diversify its funding income through social enterprise in the longer term - through offering paid-for advice or training to local businesses, for example.
Bureaux are also asking individuals and local businesses to consider supporting their work on a longer-term basis through regular giving, legacies and community support.
