Key Highlights
Highlights and quick summaries
Summary overview of national localization rules.
- ✦ CPR and CVRLocal identifier workbenches split body, prefixes, control evidence, and official lookup boundaries.
- ✦ Moms / VAT and paymentsTax, VAT, IBAN, payment reference, and reconciliation tools keep browser-only checks separate from regulated status.
- ✦ Developer debuggingCSV, JSON, API, form, privacy, fixture, and locale tools expose field breakdown and developer payloads.
Developer Notes
Developer implementation instructions
Important coding notes for storage, parameters, and validations.
- ▪ No official claimsOffline checks never prove official Denmark registry, tax, bank, vehicle, postal, or identity status.
- ▪ Field breakdown requiredEvery tool must keep named slices visible because they are the primary debugging surface.
- ▪ Same-country linksRelated workbenches stay inside /denmark/ unless a comparison route is explicitly designed.
Common Mistakes
Integration pitfalls to avoid
Locale formatting and validation traps developers frequently encounter.
- ⚠ Treating syntax as statusA passing checksum or shape check is not an official lookup result.
- ⚠ Logging raw personal dataUse masked previews for tickets, logs, analytics, and screenshots.
- ⚠ Ignoring locale separatorsUse Comma (,) and Dot (.) rules before API normalization.
- ⚠ Mixing countriesDo not reuse non-Danish examples, fallback copy, or related links in this suite.
