se-ssn

Validation for Swedish style organization numbers (organisationsnummer).

The validation checks that the first 6 chars are a representation of a valid date from the last 100 years (this behaviour can be configured, see Getting started) and that char 10 is a valid control digit based on the other characters.

Getting started

The library is available as an npm package. To install the package run:

npm install se-ssn --save

Use like this:

import {isValidSsn} from 'se-ssn'

isValidSsn('8101013608')
//=> true

isValidSsn('foo')
//=> false

// Optionally validate that a ssn is for a person of at least a certain age
isValidSsn('8101013608', {minYears: 80})
//=> false

If you are in a multinational context you can use the alias isValidSwedishSsn for clarity:

import {isValidSwedishSsn} from 'se-ssn'

isValidSwedishSsn('8101013608')
//=> true

Alternatively with CommonJS:

var seSsn = require("se-ssn")

seSsn.isValidSsn('8101013608')
//=> true
