Inconsistency in gift code/card character length

https://help.minecraft.net/hc/en-us/articles/360035130911-Minecraft-Redeeming-a-Pre-paid-Card-or-Gift-Code lists gift codes as being
12 or 25 characters long.
However, https://help.minecraft.net/hc/en-us/articles/360029977371-What-is-a-Transaction-ID- lists gift codes as being 10 or 25 characters long. One of these must be outdated or incorrect.
