The same address can be typed a dozen ways. Standardisation resolves them all to one canonical, PAF-aligned form — so your systems can match, deduplicate and ship reliably.

Frequently asked questions
What is address standardisation?
Address standardisation converts inconsistent, free-text addresses into a single consistent format that matches Royal Mail PAF structure — correct casing, ordering, abbreviations and postcode formatting.
Why standardise addresses?
Standardised addresses deduplicate cleanly, match across systems, print correctly on labels and reduce delivery errors.
How is standardisation different from verification?
Verification confirms an address exists in PAF; standardisation formats it consistently. Good tools do both together.
