Utilities to format different string on Norwegian format

This library returns hard spaces \u00a0 for formatting, so there are no line breaks in the middle of phone numbers, account numbers or other data.

formatOrganizationNumber

Format a norwegian business entity number ("brreg").

Can also check if a number looks like a brreg number, but does not currently validate the checksum.

Examples

import { formatOrganizationNumber } from 'norwegian-utils/formatOrganizationNumber'
formatOrganizationNumber('995222183') === '995 222 183'

import { isValidOrganizationNumber } from 'norwegian-utils/formatOrganizationNumber'
isValidOrganizationNumber('995222183') === true
isValidOrganizationNumber('99522218') === false

formatPhoneNumber

Provides 5 methods:

  • isValidPhoneNumber - Is the phone number a valid phone number, somewhere in the world? Will be true for both 00123467890 style, +46123467890, or norwegian 8-digit numbers 12345678. Phone number can can be passed with spaces etc. and will still pass. This is not exhausitve validation, invalid phone numbers can pass, and valid one be rejected (like the emergency number 112).
  • isNorwegianPhoneNumber - Returns true if the number looks like a Norwegian number. Does not validate short / SMS numbers ie. 112 or 32200.
  • isNorwegianMobilePhoneNumber - Returns true if the number looks like a Norwegian mobile phone number (9xxxxxxx or 4xxxxxxx). Second parameter acceptM2M can also enable validation for M2M mobile phones (58xxxxxxxxxx or 59xxxxxx) (default value for acceptM2M parameter is false)
  • shortFormatPhoneNumber - Returns the phone number, with international prefix (so Norwegian 8-digit numbers are converted to the form +4712345678). This is appropriate to compare two phone numbers for example, or to store in databases. Removes any formatting like spaces, and always prefixes with +. If the format is invalid, this simply returns the original string.
  • prettyFormatPhoneNumber - Formats the phone number for output to the user, with spaces. Avoids +47 prefix for Norwegian numbers. For example 004712345678 is formatted as 12 34 56 78. Business numbers are formatted on the form 12 34 56 78. Personal numbers are formatted as 423 45 678. If the format is invalid, this simply returns the original string.

Examples

import { shortFormatPhoneNumber } from 'norwegian-utils/formatPhoneNumber'
shortFormatPhoneNumber('112') === '112'
shortFormatPhoneNumber('12345678') === '+4712345678'
shortFormatPhoneNumber('+44 12 34 56') === '+44123456'

import { prettyFormatPhoneNumber } from 'norwegian-utils/formatPhoneNumber'
prettyFormatPhoneNumber('12345678') === '12 34 56 78'
prettyFormatPhoneNumber('+44 12 34 56') === '+44 123456'
prettyFormatPhoneNumber('0048 781-296-647') === '+48 78 12 96 647'

import { isValidPhoneNUmber } from 'norwegian-utils/formatPhoneNumber'
isValidPhoneNUmber('112') === false
isValidPhoneNUmber('+44 12 34 56') === true
isValidPhoneNUmber('0048 781-296-647') === true

import { isNorwegianPhoneNumber } from 'norwegian-utils/formatPhoneNumber'
isNorwegianPhoneNumber('112') === false
shortFormatPhoneNumber('12345678') === true
shortFormatPhoneNumber('004712345678') === true
isNorwegianPhoneNumber('+44 12 34 56') === false
isNorwegianPhoneNumber('0048 781-296-647') === false

formatAccountNumber

Formats a Norwegian 11-digit bank account number on the standard form (4, 2, 5 digits). Numbers that are not 11 digits are formatted by "best effort".

Examples

import formatAccountNumber from 'norwegian-utils/formatAccountNumber'
formatAccountNumber('36242412345') === '3624 24 12345'
formatAccountNumber('362424123451') === '3624 241 23451'

validateAccountNumber

Validates norwegian account number to have 11 digits and checking the last control digit according to MOD11 algorithm. Accepts strings with spaces and dots, those are stripped before validation. Returns true if the number satisfies the constraints and false otherwise.

Examples

import validateAccountNumber from 'norwegian-utils/validateAccountNumber'
validateAccountNumber('1234.56.78903') //true
validateAccountNumber('1234.56.78909') //false
validateAccountNumber('1234 56 78903') //true
validateAccountNumber('123437q897e9w87qw89e75678903') //false

formatAmount

Formats a number with thousand separators and 2 decimals. This is mainly appropriate for displaying currency amounts.

Accepts a options object as the second argument, two options are possible:

  • alwaysNegative: true (default: false) - Always return a negative amount (to display a debt for example).
  • decimals: false (default true) - Return the number with 2 decimals.

Examples

import { formatAmount } from 'norwegian-utils/formatAmount'
formatAmount('1000') === '1,000.00'
formatAmount('1000', { decimals: false }) === '1,000'
formatAmount('1000', { alwayNegative: true }) === '-1,000.00'
