After Snapchat revisited QR codes, Facebook (naturally) also jumped on the QR code bandwagon, in a half-hearted manner, with QR style codes for their Messenger app. 

Mashable thought they spotted a trend. 

If they did, it was a short-lived one.

No one used Facebook Messenger Codes on the Taza Control Panel.

Personally, I had one notable, related interaction. As a tepid, unenthusiastic Facebook user, I had long ago deleted the Facebook Messenger app on my phone. But I reinstalled it to check that my new Messenger Codes worked. 

In the process, I noticed a message from a friend I hadn't seen in awhile. So I responded to his message. 

His response: "Dude, I can't believe you just responded to a message I sent you THREE YEARS AGO!"

Now that's social networking.

Shortly after that interaction, I uninstalled Facebook Messenger again. Eventually, I plan to ditch the whole Facebook experience entirely. 

I won't miss Facebook Messenger codes. And besides, Facebook announced, early in 2019, that they are sunsetting Facebook Messenger Codes in August, 2019.
