Swedish Entity

Validate, format and extract data for Swedish personnummer (social security numbers) and organisationsnummer (organizational numbers).

This package also handles the temporary personal identity number known as “Samordningsnummer” (a.k.a. coordination number).

Also includes validators for Laravel.

–

The benefits of this package – while not always strictly according to the standard – is the ability to format using both short/long (10 or 12 characters) without or with a separator (i.e. 11/13 characters).

Note that companies always consists of 10/11 characters (with or without an optional separator).

This package use the excellent personnummer/php-package as it’s basis for the social security-handling, but with some additional attributes and methods.

Installation

composer require olssonm/swedish-entity

Usage

Validation

<?php
use Olssonm\SwedishEntity\Person;
(new Person('600411-8177'))->valid()
// true

<?php
use Olssonm\SwedishEntity\Organization;
(new Organization('556016-0680'))->valid()
// true

Automatically detect the entity type:

⚠️ If the detect-method fails, an Olssonm\SwedishEntity\Exceptions\DetectException will be thrown.

<?php
use Olssonm\SwedishEntity\Entity;
$entity = Entity::detect('600411-8177');
var_dump(get_class($entity))
// Olssonm\SwedishEntity\Person

Formatting

⚠️ Formatting an invalid entity will result in an exception. You should make sure to validate it beforehand.

Person

<?php
use Olssonm\SwedishEntity\Person;
(new Person('071012-9735'))->format($characters = 12, $separator = true)
// 20071012-9735
(new Person('071012+9735'))->format($characters = 12, $separator = true)
// 19071012+9735
(new Person('200710129735'))->format()
// 071012-9735

Organization

<?php
use Olssonm\SwedishEntity\Organization;
(new Organization('5560160680'))->format($separator = true)
// 556016-0680
(new Organization('556016-0680'))->format($separator = false)
// 5560160680

Laravel validators

The package registers the “entity” rule, which accepts the parameters any, organization, person or for special cases person_only_coordination and person_only_ssn.

<?php
$this->validate($request, [
    'number' => 'required|entity:organization'
]);

You may also omit the parameter and the validator will fallback to any

<?php
$this->validate($request, [
    'number' => 'required|entity'
]);

Use person_only_coordination and person_only_ssn if you for any reason only want to allow coordination numbers (samordningsnummer) and/or only SSN/personnummer.

I.e. the coordination number 850361-8335 will validate with the rule person_only_coordination, while it will fail with person_only_ssn.

This is useful when validation against for instance BankID, as they do not allow coordination numbers at the moment.

Custom messages

<?php
use Illuminate\Support\Facades\Validator;
$validator = Validator::make($request->all(), [
    'number' => 'required|entity:person'
], [
    'number.entity' => "Invalid personnummer!"
]);

Implicit validation

For the validator to run when the social security/organizational number is missing or an empty string (note, does not apply to null) you will need to implicitly state so with a required rule, i.e:

'organization_number' => [
    'required_with:company_name',
    'entity:organization',
],

or

'organization_number' => [
    'required',
    'entity',
],

Attributes

Person

Either “Samordningsnummer” or “Personnummer”*

Example

<?php
use Olssonm\SwedishEntity\Person;
$person = new Person('600411-8177');
$person->gender;
// Male

Organization

One of the following: “Dödsbon”, “Stat, landsting och kommuner”, “Aktiebolag”, “Enkelt bolag”, “Ekonomiska föreningar”, “Ideella föreningar och stiftelser” and “Handelsbolag, kommanditbolag och enkla bolag”. Note: Organizations starting with 0, 3 and 4, while technically a valid number – it is uncertain if they exist, and will return and empty string.*

Example

<?php
use Olssonm\SwedishEntity\Organization;
$organization = new Organization('212000-1355');
$organization->type;
// Stat, landsting och kommuner

Clean-helper

The Entity-class contains a clean-helper that can be useful for removing illegal characters from a social security- or organisational number:

<?php
use Olssonm\SwedishEntity\Entity;
$number = Entity::clean(' 212000-1355a');
// '212000-1355'

Note that this is not automatically applied, so you will need to clean the string before validation.

Gotcha moments

Enskild firma

EF (Enskild firma) – while technically a company/organization, uses the proprietors personnummer. Therefore that number will not validate as company/organization. Instead of using a custom solution for this (as Creditsafe, Bisnode and others do – by adding additional numbers/characters to the organizational number/social security number), a way to handle this would be:

• Work with 10 digits when expecting both people and companies (preferably with a separator). Hint: both Person and Organization will format with 10 digits (and a separator) by default via format().
• Use the detect-method to automatically validate both types

If you need to after the validation check type;

<?php
use Olssonm\SwedishEntity\Entity;
use Olssonm\SwedishEntity\Person;
use Olssonm\SwedishEntity\Organization;
use Olssonm\SwedishEntity\Exceptions\DetectException
try {
    $entity = Entity::detect('600411-8177');
} catch (DetectException $e) {
    // Handle exception
}
// PHP < 8
if(get_class($entity) == Person::class) {
    // Do stuff for person
} elseif(get_class($entity) == Organization::class) {
    // Do stuff for organization
}
// PHP 8
if($entity::class == Person::class) {
    // Do stuff for person
} elseif($entity::class == Organization::class) {
    // Do stuff for organization
}

Other/misc.

You can use personnummer.se while working with this package and building your app to generate random Swedish personnummer/social security numbers.
