Normalize serial numbers consistently
Learn why normalizing serial numbers (trim, case, separators) prevents duplicate records and failed downstream uploads.
Serial numbers often arrive with inconsistent casing, whitespace, or stray separators depending on the label and entry method.
A consistent normalization rule keeps your inventory clean and makes Intune checks more reliable.
Key points
- Trim whitespace and normalize case
- Remove obviously invalid characters
- Apply the same rules everywhere (UI + backend)
