Sweden phone number validator
How the phone number format works
- Format
- Sweden phone number in national or international (+46) format
- Example
- +46701234567
Things to watch for
- Accepts national or international (E.164, e.g. +46...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Swedish phone number doesn’t have one fixed length — like Germany, Sweden’s area codes vary from 2 digits in major cities (08 for Stockholm) to 4 digits in smaller towns, with the local number shrinking as the area code grows. Mobile numbers are more consistent: 07 followed by 7 more digits (070 123 45 67). The constant across both is the leading 0, a national trunk prefix dropped the moment +46 is added.
How this validator works
Enter the number nationally (0701234567) or in full international form (+46701234567); the check runs Google’s libphonenumber against Sweden’s real numbering-plan ranges — area-code length, mobile prefix, and total digit-count bounds — entirely client-side. Because landline length varies so much by region, this validator checks the range tied to each specific area code rather than a single fixed total, the same approach needed for Germany’s numbering plan.
What a pass doesn’t tell you
A pass means the digit count and prefix combination is possible under Sweden’s real numbering plan — it doesn’t mean the number is currently connected. Format validity and live-line status are separate questions this tool doesn’t answer.
Scope: use this to filter out impossible Swedish numbers — wrong length for the area code, a stray digit, a kept trunk 0 after +46 — before they reach a form or CRM. It won’t confirm the person on the other end picks up.

phone number FAQ
Why don't all Swedish landline numbers have the same length?
Sweden's area codes range from 2 digits in major cities (like 08 for Stockholm) to 4 digits in smaller towns, with the local subscriber number shrinking to compensate — so total length varies by region even though every number is still valid.
What happens to the leading 0 when converting a Swedish number to +46?
It's dropped. The 0 in 070 123 45 67 is a national trunk prefix, so the international form is +46701234567 — no 0 survives after the country code, for mobile or landline numbers alike.
Does a valid Swedish number check confirm the line is active?
No. It only confirms the digits match a real Swedish mobile or landline pattern — it can't confirm the SIM is topped up or the landline connected, since format validity and live-service status are separate things this tool doesn't check.
