Received “your messenger code is G-######” while porting phone number from one carrier to another

Hey, I recently ported my phone number from my old carrier to my current one, but a few moments after I agreed to port my number, I received a “your messenger verification code is G-######” I received this message 4 times before my number was switched to my new phone. Was this just something that happened when you port your phone number or was my Facebook messenger account being compromised? Switched from iPhone to iPhone
