I would like to bring awareness to similar call signs. We departed as flight 1234. We soon found we were following flight 3412 through similar airspace as we were switched to the same frequencies 4 times. While there were no errors on our part or ATC; the ATC controllers commented on this being a confusing situation. 3412 and 1234 are easily confused.
B737 pilot reported similar sounding call sign on the same route could have caused confusion.
