How can I identify different pickups?

[RepVenom]

This is just a question that's been on my mind for a little bit. But how can you identify and tell the difference between the different Seymour Duncan pickups? For example let's say you are installing a DD in the bridge of your guitar and a Jazz in the neck but when you take the pickups out of the boxes and set them out on the table you get them mixed up. Do the pickups say what kind they are on the back or something?

most have asticker on the bottom that tells you what it is. if you lose the sticker, youll need a multi meter to test the resistance
