You can look up your lineal number in Navy Standard Integrated Personnel System (NSIPS) – (Click link on the side)
1. Once logged into NSIPS - Select the View Personal Information link.
2. Select Member Data Summery and you will find your Precedence Number at the bottom.
3. Click the spreadsheet link on the right for estimated zone calculations. Find which Fiscal Year (FY) range your lineal number falls in. Each FY board is held during the previous year. For example, if your number falls in the FY19 O4 board, this board will meet in May of 2018. Please NOTE: These are merely zone projections based on historical averages - if your lineal number is "right on the border" - you may shift one year to the left or right (whichever the case may be).
