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.
Source hierarchy and review cadence
| Topic | Preferred evidence | Review trigger |
|---|---|---|
| Numbers and locale behavior | Unicode CLDR/LDML, ECMA-402, and runtime Intl output | Review after relevant CLDR/runtime changes and quarterly spot checks |
| Currencies | ISO 4217, central banks, and monetary authorities | Review on announced transitions and quarterly reconciliation |
| Addresses | UPU S42 concepts and documented country templates | Review quarterly and when postal guidance changes |
| Phone numbers | ITU-T E.164 and versioned libphonenumber metadata | Review with dependency updates and numbering-plan changes |
| Engineering guidance | Platform specifications and official vendor documentation | Review when cited APIs or standards materially change |
Verification process
- Prefer the governing standard, standards body, central bank, postal authority, platform specification, or official library documentation.
- Record exact effective dates for transitions and label superseded data as historical.
- Compare generated pages for consistent metadata, canonical URLs, headings, schema, and internal links.
- Run privacy, lint, TypeScript, fixture, production-build, and local-crawl checks before publication.
- 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.

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.
