There are a lot of different manufacturing codes for just the screen, as long as you search for "A1502 2014 LCD" (2013-2014 compatible, 2015 won't work) and look for the LCD panels, you will find it.
One of the codes for the screen is LP133WQ1. The letters following this do not matter, (EV, E1, A1, etc), they are all compatible.
Be warned, this repair is extremely difficult, and if you have no experience, you will mess up. If you shatter the screen too much when removing, the LCD liquid may leak onto the backlight, you can scratch the backlight, leave dust under the screen when fitting, damage the new screen and the list of what can go wrong will go on...
If you are looking to do this and are a repair business, start on MacBook Air LCD only replacements, they are 100x easier and can be done in 30m-1hr, and you come across similar obstacles. If you have never done complex screen replacements before, don't bother unless you don't mind the quality possibly being bad, or accidentally cracking the new screen whilst fitting.
If you decide to try this, make sure to get a screen which is from original Apple packaging, which is now possible to get for this year since it is old stock. This will have a protective film on the back with red writing and either have no protective film on the front glass (plastic sheet instead) or a plastic film with red writing on. If the film has been peeled up before, or does not have the writing, you are being sold a defective screen from LG/Samsung's faulty pile, which has had the film reapplied. Make sure you test it before fitting too, you won't be able to remove the screen without cracking it.
A lot of info, but I hope this helps. I have replaced around 250 A1425/A1398/A1502/A1534 screens by now, so if you decide to do this and get stuck at any point, feel free to ask :)
EDIT: Packaging original 100% new assemblies come in.
