How to Fix ZIP Code Format Errors in OSHA ITA CSV Files
The ZIP field is not a valid five- or nine-digit value.
What this means
OSHA's CSV field expects a clean ZIP value. Dashes, spaces, missing digits, and spreadsheet conversions can create rejected values.
Why this happens
- ZIP+4 was exported with a dash.
- Leading zeroes were stripped.
- The field contains a city/state value instead of ZIP.
- The column was formatted as a number.
How to fix it manually
- Use five digits or nine digits without a dash.
- Restore missing leading zeroes.
- Remove spaces and text.
- Check that the ZIP belongs to the establishment address row.
