The Teensy 3.2 I've been working with now changes its serial port number every time I upload new code. This is a fairly recent development. What could be the cause? Both the Arduino IDE and PlatformIO have trouble with this because they can't reuse the existing serial port window. My platform is the latest OSX with a 2.5-year-old MacBook Air.
Constantly changing serial port number?

Generally no - but I use Windows.
I also generally use TyCommander that doesn't care about the COM# - it tracks the Teensy by reported Serial Number.
There is a TyComm thread ( TYQT ) - the latest version a few days old is here

Definitely not happening here on my Macbook Air (early 2015 model) running Sierra 10.12.4.

@ Franky_74 This is standard Windows behavior. Whenever you add a device with a new serial number it assigns a new COM port. Couple of years ago we had massive issues in production due to that. Changing a registry setting finally fixed it. Google for "IgnoreHWSerNum"

That's exactly the way Microsoft and Apple designed their systems. Each Teensy is supposed to get its own unique COM port number (Windows) or device name (Mac). When you plug in a new Teensy, you get a new number. But the number is supposed to remain the same for each Teensy. If you plug the original Teensy in again, it's supposed to have the same number it did earlier. If you use 90 different boards, you get 90 numbers. If you plug each one in twice, you should *not* get 180 numbers. Each is supposed to retain the same number every time you plug it back in.
Mac and Windows both use the USB serial number to accomplish this. Every Teensy 3.x and LC has a unique serial number.
If you edit the USB code, in usb_desc.c, you can change the serial number to anything you like. You could set it to a constant, for example. Then your PC would believe it's seeing the exact same Teensy.

As Paul mentioned, this is by design...
However with my DEV machines where I play around with lots of different chips/boards, over time the number of devices gets really large. So every once in awhile I will purge my system of most of these comm ports. If you google something like: "How do I remove unused com ports on windows" you will get many hits, including:

Same thing has just started happening to me. I've been using a number of teensy 3.6's and uploaded code and to date, I've only had to change serial port when changing the teensy.
However today, everytime I upload code to the same Teensy, it increments the serial port to the next one and I have to find it and reconnect to it. Osx Sierra, Arduino 1.8.5.
Also happens when I power cycle the teensy too.

Please give the latest beta version a try. It has new (hopefully improved) handling of port detection and a redesigned serial monitor which natively connects to the port (not using Java).
https://forum.pjrc.com/threads/50254-Teensyduino-1-42-Beta-3
When you use this, you should see the port twice in the Ports menu. The "Teensy" section is the native access, and the "Serial" section is the old Java-based stuff. Select it from the new part.
In this new version, we're able to collect a lot more info in Teensy Loader's Help > Verbose Info window. If things still are going awry, please open the verbose info window and use the Log menu to save all the message to a text file. Then you can post the file here (use "Go Advanced" to get the forum's editor that lets you attach a file to your message).
I'd really like to get to the bottom of this strange Mac problem, so I really hope you'll have a little time to use the beta version and capture that log file (and maybe redo a few times as we try to figure out what's really happening and come up with a fix).
So before upgrading, I verified it was still happening (1.41 Teensy loader BTW), also quit Arduino IDE and Teensy Loader and restarted them, again still happening.
Upgraded to 1.42 Beta 3 and set to the "Teensy" Port. Port still increments on every upload, however the difference now is Serial Monitor keeps track of the port change and I don't have to manually reselect the port each time, which is great.
Here's the verbose log across 2 uploads with the same device without disconnecting anything showing the port increment happening:
