  • Is enterprise edition or customer attributes extension? Or do you mean CUSTOM attribute?

So the reason for this is because:

customer attribute code can have prefix "customer_" and its length must be max length minus prefix length

Now the code for the limit can be found at app/code/core/Enterprise/Customer/Block/Adminhtml/Customer/Attribute/Edit/Tab/Main.php where it uses the constant Mage_Eav_Model_Entity_Attribute::ATTRIBUTE_CODE_MAX_LENGTH

So it appears that normally a EAV attribute has a limit of 30 characts, so product and customer. As to why this limit is in place I am sorry but I dont know. The table seems to allow 255, maybe someone else can tell you why.

There are some thoughts behind this limit here
