&gt; Heaven forbid someone just add an SSN to student ID lookup table to the database.<p>Why does a school even need this number?<p>The only groups that need this number are financial institutions of all types (including employment and borrowing) and government agencies.<p>A school does not need it. If they lend you money then that department might, but no further.<p>What I do when places that don&#x27;t need the number ask for it is pretend I don&#x27;t remember it. So far I&#x27;ve not had any problems, they mange just fine without it.
