Verizon Communications said US federal, state and local law enforcement authorities have requested 320,000 items of customer information in 2013, making it the latest US company to go public about the data requsts from law enforcement agencies.
The requests for customer data included over 164,000 subpoenas and about 71,000 court orders in the year.
According to the Verizon report, much of the requests were made for information related to consumer customers compared to the corporate or enterprise customers.
Verizon said it does not release customer information unless authorised by law, such as a valid law enforcement demand or an appropriate request in an emergency involving the danger of death or serious physical injury.
"The orders compel us to provide some type of information to the government," Verizon added.
The report revealed that the company had received about 1,500 wiretap requests in the year and about 1,000 to 2,000 National Security Letters that are sent from government agencies like the Federal Bureau of Investigation.
"We are not permitted to disclose the exact number of National Security Letters that were issued to us, but the government will allow us to provide a broad range," the report said.
In 2013, the company received around 3,000 requests from Germany, while requests from France and Belgium reached 1,347 and 473, respectively.
"These figures reflect requests made by law enforcement within a country for data stored within that same country," the report added.
Verizon has also limited the access to certain websites in foreign countries and blocked around 1,200 websites in Colombia that were considered to host child pornography.
