The receipts
The numbering system used on receipts has significance.
For most applications filed at a Service Center, your receipt may look like this: LIN 99 001 50001.
In this example, the LIN represents the Nebraska Service Center, where the application was initially received into the electronic system.
• The 99 represents the fiscal year (October 1, through September 30) in which the case was received.
• The 001 represents the computer workday in the fiscal year on which the fee was taken.
• The 50001 represents the particular case number.
For cases with particular case numbers starting with a 5, electronic case status information is available. For cases with particular case numbers starting with a 0, you must write to request the status of your case.
