Developer Checklist

Integration checklist reminders

Important checkmarks to verify when deploying localized pipelines.

☑ Normalize BSN, KVK, RSIN, BTW, IBAN, postcode, and phone values before storage.
☑ Keep raw personal identifiers out of logs; use masked values in support and analytics payloads.
☑ Treat KVK, VIES, BAG, bank ownership, DigiD, and RDW status as official external lookups.
☑ Place country-specific IBAN validation under the Netherlands hub even when the global IBAN tool exists.

Key Highlights

Highlights and quick summaries

Summary overview of national localization rules.

✦ Netherlands now ships as a full premium country suite rather than a metadata-only hub.
✦ Every workbench runs locally in browser and exposes official lookup boundaries.
✦ BSN, KVK, BTW, IBAN, postcode, iDEAL, SEPA, BAG, RDW, AVG, and audit-file workflows are linked from the country hub.

Developer Notes

Developer implementation instructions

Important coding notes for storage, parameters, and validations.

▪ Use nl-NL display only at the UI boundary; keep normalized canonical values in storage.
▪ Mask BSN, IBAN, phones, and document-like values before logs, screenshots, or telemetry.

Common Mistakes

Integration pitfalls to avoid

Locale formatting and validation traps developers frequently encounter.

⚠ Using a BSN checksum as proof that a person exists.
⚠ Displaying raw long samples in dropdown labels instead of short human labels.
⚠ Treating global IBAN validation as enough for Dutch bank-code and account slicing.
⚠ Forgetting house-number additions when preparing BAG lookup payloads.

Code Examples

Normalize Dutch postcode

available
