The firm is also said to be using Here's location data for geocoding on Facebook, Instagram, and Messenger, apart from using Here maps in Android apps of Instagram and Messenger.
"We are testing Nokia HERE maps across Facebook to give us more control and flexibility in delivering a consistent maps experience," a Facebook spokesperson confirmed to TechCrunch by email.
"I can confirm that we're testing HERE maps in Android versions of some of our standalone apps like Instagram and Messenger as well."
"We're excited that our maps can be enjoyed by Facebook users,"a Here spokesperson told Tech Crunch.
That doesn't mean that Facebook has secretively acquired Nokia's Here maps. Last month, Nokia had confirmed that it is looking for a buyer for its HERE Maps division which has an estimated value of $2 billion.

Facebook isn't the only potential buyer tipped to be thinking of buying HERE maps service, other big names that are willing to pay for Nokia's maps division are Apple, Yahoo, Alibaba, Amazon, among others.
As of now, it is not clear as yet on whether Facebook is indeed interested in buying Nokia's mapping software division. We'll update the article once we've have more information to share.
