This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@adriantombu/siret-to-vat) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

SIREN/SIREN to VAT number

This small library converts a French SIREN or SIRET to a valid VAT number. You can then use the vat number library to check it against the official European records.

How to use it

Install the library first with yarn add @adriantombu/siret-to-vat
And then import it in your script

const { convertToVatNumber } = require('@adriantombu/siret-to-vat')

const siren = 817871668
const vat = convertToVatNumber(siren)

{
  vatNumber: "FR16817871668",
  valid: true
}

In case of an invalid number, you will receive the following result, with the value valid set to false

const { convertToVatNumber } = require('@adriantombu/siret-to-vat')

const siren = 123456'
const vat = convertToVatNumber(siren)

{
  vatNumber: 123456',
  message: 'The number provided must be a SIREN (9 caracters) or SIREN (14 caracters)',
  valid: false
}
