Sweden TIN validator
Review the expected Sweden Personnummerstructure before you save it, send it to an API, or include it in a tax workflow. Interactive validation appears only after this country's rules pass authoritative-source verification.
Private by design
Transient validation, no public history
TINs are sent securely to the canonical validation API, processed in real time, and not persistently stored by the public checker.
How Sweden tax IDs are formatted
In Sweden, the tax identifier is commonly known as Personnummer (Personnummer). The expected format is 10 digits (YYMMDD-XXXX) with Luhn checksum. Teams usually need a Sweden Personnummer check around tax registration, healthcare, banking, or before a record moves into billing, onboarding, or compliance review.

How to check a Sweden Personnummer
Use this check before a record reaches billing, tax reporting, or manual review.
Enter the Personnummer
Paste or type the Sweden tax identifier exactly as it appears in your source record. Spaces and separators are fine when they are part of the expected format.
Review the format result
Check whether the number matches the Sweden syntax currently implemented here. The result does not query a tax-authority registry or confirm ownership.
Confirm important records
For onboarding, tax reporting, or compliance work, treat the result as a data-quality signal and confirm high-risk records with Skatteverket or your internal process.
