What address validation does
Validation checks that an address exists and is deliverable, then returns it in a consistent, structured format. It is the difference between a database full of guesses and one you can trust.
Where it helps
- Checkout — Block undeliverable addresses before an order is placed.
- Onboarding — Keep customer records accurate from day one.
- Data cleansing — Standardise and verify existing records.
