Google said it is negotiating with the US government about what details it is able to reveal regarding data requests made by government agencies.
The company said the "sticking point" is whether it can only publish a combined figure for all requests, Reuters reported.
Google said that would be "a step back for users" because it already breaks out criminal requests and National Security Letters, another type of intelligence inquiry.
Microsoft has announced it received between 6,000 and 7,000 criminal and national security warrants, subpoenas and orders from US government agencies in the last six months of 2012.
The firm said the requests from local, state and federal level affected between 31,000 and 32,000 consumer accounts.
The software firm disclosed the data after a deal was reached with US national security authorities about such disclosures.
Facebook has announced it received between 9,000 and 10,000 requests for user data from US government entities during the second half of 2012.
Ted Ullyot said on Facebook's website that these requests "run the gamut - from things like a local sheriff trying to find a missing child, to a federal marshal tracking a fugitive, to a police department investigating an assault, to a national security official investigating a terrorist threat".
Mr Ullyot said the requests involved 18,000 to 19,000 Facebook users' accounts.
"We will continue to be vigilant in protecting our users’ data from unwarranted government requests, and we will continue to push all governments to be as transparent as possible", he added.
Several internet companies have struck an agreement with the US government to release limited information about the number of surveillance requests they have received from them, Reuters reported citing sources familiar with the discussions.
The companies are expected to release details without revealing how many requests originates from a controversial National Security Agency programme that was intended to gather intelligence about non-US residents, the sources added.
