Technical Note: Character ID Ranges
Greetings developers,
Quick info dump here. Up until now, all character ID's have been totally sequential and existed in rigidly defined ID ranges. In support of the influx of new players from the Ascension release, we are laying the groundwork to move characters into a non-sequential range (much like citadel ID's). More news on that will come next year (no need to panic ^_^), but for right now, you should know that all new characters on singularity are being created with ID's starting from 2112000000. This change will be released on TQ next Tuesday, 13th Dec 2016.
For the time being, these new character ID's will remain sequential. However, CCP makes no guarantees that this will continue to be the case, and caution against encoding that assumption into your application logic as a long term strategy.
(And yes, once we're closer to the time, we'll be looking at endpoints to allow you to discover new characters, I know a few of you need a way to do that).
