Did anyone get the application number starting with NBC*XXXXX. I got mine like that, while on USCIS website they say your application number for N-400 sould start with SRC, EAC, WAC, LIN. Since mine seems to be unique, even though my case is progressing smoothly I am unable to check the case status online. When I put my application number starting with NBC*XXXXXX I get the following message, so I am basically unable to check my case status online and I could only come to know about any progress when a paper letter is delivered at my postal address. Does anyone have same situation or I am doing something wrong?

Dashes ("-") should be omitted when entering a receipt number. However, all other characters, including asterisks ("*"), can be included if listed on your notice as part of the receipt number.
Listed above are the possible steps an application or petition may go through during processing. Not every application or petition will spend time in each of these steps.
