Civitas.Id.Sweden

AOT-native .NET library for parsing, validating, and formatting Swedish official ID numbers (personnummer, samordningsnummer, organisationsnummer). Zero third-party runtime dependencies.

Install

dotnet add package Civitas.Id.Sweden

Usage

using Civitas.Id.Sweden.Core;
using Civitas.Id.Sweden.Format;

// Parse and validate
var person = PersonalId.Parse("198112189876");

// Read core facts
DateOnly birth = person.BirthDate;
bool adult = person.IsAdult();

// Format
string long12 = person.LongFormat();              // "198112189876"
string short10 = person.ShortFormat(PnrFormat.ShortFormat);            // "8112189876"
string short11 = person.ShortFormat(PnrFormat.ShortFormatWithSeparator); // "811218-9876"

// TryParse never throws
if (PersonalId.TryParse("198112180000", out var maybe))
{
    // ...
}

// Sealed sum type: PersonalId, CoordinationId, OrganisationId all : SwedishOfficialId
var any = SwedishOfficialId.ParseAny("5567203067");  // OrganisationId
