NAVY ADMIN GUIDE
Navy Serial Number & Sender Identification Block
The sender-identification block helps identify, classify, and track correspondence. The exact serial/originator practice can vary by organization, so the value of a tool is precise placement—not inventing the number.

What to verify
- Correct SSIC for the subject
- Correct originator code or serial practice for the command
- Correct date
- Alignment near the right margin as required by the format
Do not generate fake tracking numbers
MilAdmin can place the information you enter, but local serials, correspondence numbers, and originator codes must come from the command’s actual process.
Common formatting problem
When the block is positioned with spaces, it shifts as fonts or page settings change. Use real alignment settings instead.
