# FAQ: Why Do Results Differ Between Sources?

## Answer

Different sources may hold different data because they collect information for different purposes, update at different times, receive data from different contributors and apply different matching rules. A difference between sources should be reviewed before being treated as an error or fraud indicator.

## Key points

- One source may be more authoritative for a specific field than another.
- A source can be current for one attribute and incomplete for another.
- Timing delays can occur after a person changes details or after a contributor updates records.
- Matching rules affect whether a result appears as match, partial match or no match.

## What to do next

- Identify which source is authoritative for the disputed field.
- Review the original input data and supporting documents.
- Use the relevant dispute or correction process.
- Document the source used for any decision.
