The company aims to increase its delivery of information services in the mobile and internet sectors and as a result needs to expand its marketing resources.
VCCP will undertake additional work that is "over and above" existing streams of European campaign planning and implementation.
The roster of 12 agencies working for The Number across Europe includes WCRS, which created the UK launch ads for the 118 118 brand in 2003.
The Number is a wholly owned subsidiary of US directory enquiries provider KGB and operates in six European territories with a portfolio of information services.
Its roster of European business includes the full range of 118 and related information services offered via voice, web and mobile.
Earlier this year the company extended beyond its core offering with the launch of an instant SMS information service that claims to answer any question.
It was supported by a WCRS-created ad campaign featuring the 118 118 runners transformed into grey-haired boffins.
The full European agency roster comprises: Agence.V, Bell Pottinger, Heneghans, Hive, Kassius, Lowe Worldwide, Naked, OMD, Resonate, Springer & Jacobi, WCRS and VCCP.
