From the .Net SDK or AdminUI try to change the UserId field manually to set it equal to the same number as the UesrName and it keep rounding it up!!!

{
  "CreatedTime": "/Date(1349565534259-0700)/",
  "UserId": 634851623342592800,
  "UserName": "634851623342592724",
  "recType": "fbUser"
}

I just wanted to follow up here for anyone else who might read this post.

The reason for this error is that most javascript engines only support numbers up to 2^53. We have added this to our docs.

You're hitting a limit of most (if not all) JavaScript engines. They can't represent number larger than 2 ** 53. 
See the following in node (V8) and Spidermonkey:

Anyone who wants to store such large numbers, will have to store them as strings.
