Error Solver
How to fix: Value '...' is not facet-valid with respect to pattern '[0-9]{4}' for type 'Last4SSNType'.
What happened?
The WH-347 portal requires Employee ID to be exactly 4 digits — typically the last four of the SSN. Full SSNs, employee codes like 'EMP-0421', or names in this field will trigger a rejection. This is one of the most common first-time submission errors for small contractors.
The Zero-Tolerance Solution
XMLExpress automatically detects and truncates full SSNs, strips non-numeric characters, and preserves leading zeros — so 'EMP-0421' becomes '0421' and '123-45-6789' becomes '6789' — without any manual editing.
