ACM: Dutch telecom operator KPN must retroactively adjust tariffs for porting phone numbers
Dutch telecom operator KPN must retroactively adjust its tariffs for porting phone numbers. This has been decided by the Netherlands Authority for Consumers and Markets (ACM) following objections raised in an earlier decision about those tariffs.
On January 29, 2019 ACM decided that KPN should use lower tariffs for porting phone numbers to another telecom operator. Those tariffs have now been lowered. Following objections filed by KPN, Voiceworks, and other telecom operators, ACM re-assessed the tariffs, and concluded that they had been set correctly. The tariffs therefore remain unchanged. However, the tariffs should apply retroactively from January 18, 2017 (the date ACM first received any complaints), instead of the original date of March 1, 2019. KPN is responsible for the implementation of the decision.
Customers that switch from one telecom operator to another have the option of retaining their phone numbers. A telecom operator may charge the other operator for the porting of phone numbers. Telecom operators can subsequently charge their customers these costs.
In order to ensure that these costs do not discourage customers from switching operators, the law prohibits porting tariffs from exceeding the actual costs that an operator incurs (cost-oriented tariffs). ACM established that KPN's tariff of 200 euros per number block (multiple numbers that belong together, for example belonging to a single company) was much higher than the actual costs. The tariff of 2 euros per number proved to be too high only from October 2017. KPN has adjusted its tariffs to 1.15 euro per number and 42.80 euros per number block.
