The Union of Citizens Advice Bureaux / Związek Biur Porad Obywatelskich (ZBPO) of Poland is a national organisation that has been operating since 1998. Its activities are modeled after the Citizens Advice system functioning in Great Britain.

20 local Citizens Advice Bureaux are currently associated within the Union. These CABs provide free advice services to all persons in need. Advice services are provided primarily in the areas of: housing, debt, family allowances/assistance, ownership, inheritance, employment and many other social problems. Trained and skilled advisors provide services, maintaining the standards of confidentiality, no charge, provision of up-to-date and reliable information, care and oversight of the quality of the services offered. 

In 2017, CABs assisted 12 553 persons by addressing nearly 20 000 problems. 

ZBPO has been a member of CAI since its founding. Through CAI and ECAS, it participates in international projects on behalf of promoting citizens advice services. 

In Poland, ZBPO operates a website with information for the general public on the most frequently experienced problems of clients, operates e-mail advice services, advocates support for the provision of citizens advice services with national authorities, and supports the development of know-how and new skills among local CAB advisors. The Union was a partner in a 3-year national project headed by the Ministry of Labour and Social Policy to develop systemic solutions to make citizens advice and legal services more generally available in Poland and to promote greater awareness about these services in society.
