Call Before You Dig, LinesearchbeforeUdig & KLIC: the differences

Call Before You Dig (CBYD), Click Before You Dig (CBYD), Dial Before You Dig (DBYD) or LinesearchbeforeUdig. These are all systems that allow you to partially query where to expect cables and pipes. In the Netherlands, the approach is very different: there has been, a completely legal, incredibly advanced and extensive system in place for years and the data is mandatory to provide by network operators but also mandatory for excavators to consult for every excavation.

Known as: KLIC.

Going to excavate mechanically? You will have to do a Klic request. In the Netherlands you are obliged to request information of cables and pipes prior to digging. This is mandatory by doing a Klic request: you can do a Klic request here.

Call Before You Dig

811 is the national U.S. call-before-you-dig phone number. Anyone who plans to dig in U.S. should call 811 or go to their state 811 center’s website before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don’t unintentionally dig into an underground utility line. In the United States of America, this is a free initiative and service of Common Ground Alliance. 

Click Before You Dig

Whether you’re planning a home improvement job, planting a tree or installing a fence or deck, Click Before You Dig to safely identify buried utility lines. This is a service for states in America and Canada. The Click Before You Dig portal is provided by the Canadian One-Call Centres Committee in cooperation with the Canadian Common Ground Alliance. By clicking on a state, you can enquire by phone or via an internet form where to expect the cables and pipes.

Dial Before You Dig 

Dial Before You Dig (DBYD) is the online version of Gas Networks Ireland. Besides that you also have BYDA (Before You Dig Australia), formerly Dial Before You Dig (DBYD). That is the national Before You Dig organisation that provides the free excavation referral service for the Australian community. 


LinesearchbeforeUdig (LSBUD) is a free to use service that any individual (User) can use to check their works against over asset owners’ (Members) utility assets. These assets include hundreds of thousands of kilometres of underground and overhead pipes and cables in the electricity, gas, high pressure fuel, water and fibre optic networks.

So: In all the above examples, there is no legal requirement to provide data. As a result, the data to be consulted is not always accurate or complete.

In addition, in the case of mechanical soil excavation, it is also not compulsory in the above countries to use these systems.


In the Netherlands, this is regulated quite differently. In the Netherlands, the WIBON (formerly WION) Act applies, which stipulates that network operators are obliged to submit the location data of cables and pipelines to one central system.

On the other hand, you have the soil excavators, who are obliged, prior to any machine excavation, to enquire where to expect these cables and pipes. Even if a cable or pipeline is not located where it should be according to the Klic notification, this must be reported.

In short, the Dutch Klic system is a highly advanced, complete and safe way to excavate near cables and pipes. This with the aim of preventing damage to underground assets.

So are you going to excavate mechanically? You will have to do a Klic request! So pay attention to the obligation! Request a Klic request in time.
