Trackable codes for Mega Event

[+ShammyLevva]

I'm the Vice Convenor of the Aberdeenshire UK Mega 2019. This will be the 12th Annual UK Mega event. I'm aware that we will get a "support bundle" that will include 50 trackable codes that will be prefixed for the Mega I'm assuming AM prefix? At what point would these codes be issued? What is the process for getting them. The online application suggests applying for Mega status 15 months before event yet Yorkshire that will host the 2018 event in August 2018 already have their YM trackable codes.

 

If we go ahead and purchase trackable codes I understand the minimum is 50 codes at $1.50 each however the minimum for getting a custom prefix is confusing as the official post on the matter http://forums.Groundspeak.com/GC/index.php?showtopic=116641 says at one point the minimum is reduced to 250 for a prefix. Yet in the last post in that thread it refers to the (old?) 1000 maximum. So the official thread is contradictary. Can someone clarify please, ideally a moderator/lackey.

 

Thanks in advance for your assistance.
