The heads of foreign and domestic intelligence would hold talks with the White House and the National Security Agency, a government spokesperson said.
Earlier, Germany and France said they wanted the US to sign a no-spy deal by the end of the year.
EU leaders have warned a lack of trust could harm the fight against terrorism.
As well as the bugging of Merkel’s phone, there are claims the NSA has monitored millions of telephone calls by both German and French citizens.
Spain on Friday followed Germany and France in summoning the US ambassador to explain reports of spying on the country. Italy has also expressed anger at reports it too has been spied on.
