Key Highlights
Highlights and quick summaries
Summary overview of national localization rules.
- ✦ SSN and EINLocal identifier workbenches split body, prefixes, local vocabulary, and official boundaries.
- ✦ IRS tax ID and paymentsTax, banking, payment reference, and reconciliation tools keep browser-only checks separate from regulated status.
- ✦ Developer debuggingCSV, JSON, API, privacy, OCR, locale, and data-quality 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 United States registry, tax, bank, postal, identity, or legal status.
- ▪ Field breakdown requiredEvery tool must keep named slices visible because they are the primary debugging surface.
- ▪ Same-country linksRelated workbenches stay inside /united-states/ 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 shape check is not an official lookup result.
- ⚠ Logging raw personal dataUse masked previews for tickets, logs, analytics, and screenshots.
- ⚠ Ignoring local separatorsUse Dot (.) and Comma (,) rules before API normalization.
- ⚠ Mixing jurisdictionsDo not reuse non-US examples, fallback copy, or related links in this suite.
