Editorial responsibility

Content is published under the localization.guide organizational identity. Personal names and personal email addresses are intentionally not published. Technical pages identify their reviewed date and link to the primary or official sources used for time-sensitive claims.

Verification process

  1. Prefer the governing standard, standards body, central bank, postal authority, platform specification, or official library documentation.
  2. Record exact effective dates for transitions and label superseded data as historical.
  3. Compare generated pages for consistent metadata, canonical URLs, headings, schema, and internal links.
  4. Run privacy, lint, TypeScript, fixture, production-build, and local-crawl checks before publication.
  5. Keep uncertainty visible; formatting, syntactic validation, assignment, and real-world deliverability are not presented as interchangeable.

Corrections

A correction report should include the affected URL, the disputed field or statement, an authoritative source, the relevant effective date, and the expected replacement. Do not include private personal data.

Confirmed corrections update the page’s reviewed date and, for material factual changes, its sitemap modification date.

Limitations

Locale, monetary, postal, and numbering data changes. The site is an engineering reference rather than legal, financial, postal-deliverability, or telecommunications-assignment advice. Check the linked authority when a decision requires current regulatory or operational certainty.
