Address validation vs verification: what is the difference?
Validation, verification, autocomplete, standardisation. The terms get mixed up; here is what each means.
Guides
The terms, defined
- Autocomplete — Suggesting addresses as a user types.
- Validation — Checking that a given address exists and is deliverable.
- Verification — Often used interchangeably with validation.
- Standardisation — Reformatting an address into a consistent structure.
How they work together
Most teams combine these. Autocomplete captures a clean address at entry, validation confirms it, and standardisation keeps every record in the same format. The result is a database you can trust.
