library2.1.0jsnpmunverified

Telefonnummer is a Swedish phone number formatter and parser (v2.1.0, stable). It formats both mobile and landline numbers to a standardized format with area code support. Includes functions for parsing, validation (with optional mobile-only check), area code lookup, normalization, and equality comparison. Ships TypeScript types. Updated infrequently, last release 2023-09-01. Key differentiator: focused solely on Swedish numbers with official area code data from PTS.

Install & Compatibility

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

parse

✓ import { parse } from 'telefonnummer'

✗ import parse from 'telefonnummer'

parse is not a default export; it's a named export. Using default import will result in undefined.

validator

✓ import { validator } from 'telefonnummer'

✗ const validator = require('telefonnummer').validator

CJS require works but ESM import is preferred for TypeScript projects.

areaCode

✓ import { areaCode } from 'telefonnummer'

✗ import { areaCodes } from 'telefonnummer'

areaCode is singular, areaCodes is plural and returns an array. Common mistake: confusing these two exports.

Demonstrates parsing Swedish numbers, internationalization option, validation, area code lookup, and numbering area lookup.

import { parse, validator, areaCode, numberingArea } from 'telefonnummer'; // Parse a mobile number const formatted = parse('0701234567'); console.log(formatted); // '070-123 45 67' // Parse with internationalized format const international = parse('0701234567', { internationalized: true }); console.log(international); // '+46701234567' // Validate a landline number const valid = validator('081234567'); console.log(valid); // true // Get area code for a city const code = areaCode('Stockholm'); console.log(code); // '08' // Get numbering area for a code const area = numberingArea('031'); console.log(area); // 'Göteborg'

Debug

Known issues

deprecatedDefault export (parse) may be removed in future versions.

fix

Use named import { parse } instead of default import.

affects: >=1.0.0

gotchaparse() may return 'Röstbrevlåda' (Swedish for 'Voicemail') for numbers like '222' instead of a formatted number.

fix

Check the returned string for unexpected literal values when parsing short numbers.

affects: >=2.0.0

gotchaThe package only handles Swedish phone numbers; international numbers will not be formatted correctly.

fix

Use libphonenumber-js or google-libphonenumber for international numbers.

affects: >=1.0.0
