Zone match
Postcode data identifies a likely local authority and matches it to the published catalogue.
Charge estimate
Registration data can inform an estimate. The authority page is the final source for vehicle class, exemptions and payment.
Local search with a national product
ULEZ and CAZ queries are local. The proof shape is the same one AffixIO sells for any eligibility gate.
Confirm the authority
Class rules live on the charging authority page. This demo does not replace that.
