- North Korea phone number in national or international (+850) format
- Example
- +8501921234567
Things to watch for
- Accepts national or international (E.164, e.g. +850...) 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 North Korean phone number runs under country code +850 with a 10-digit national number, following the same E.164 shape as any other country’s numbering plan — but the resemblance to an ordinary phone number ends there. North Korea’s telecom system is among the world’s most restricted: most citizens’ mobile lines, largely carried by the state-linked Koryolink network, cannot dial internationally or reach the open internet at all, connecting instead to Kwangmyong, the country’s isolated domestic intranet.
How this validator works
Enter the number in national form (1921234567) or full international form (+8501921234567); this tool checks the digit count and prefix against North Korea’s real numbering plan using Google’s libphonenumber, entirely client-side. The check confirms shape only — it has no way to know whether a given line belongs to the small foreigner-facing segment of the network or an ordinary domestic subscriber cut off from international calls entirely.
What a pass doesn’t tell you
A pass confirms the digits fit North Korea’s real numbering plan — it says nothing about whether that specific line can be dialed from outside the country, since most domestic mobile numbers there simply can’t be.
Scope: useful for catching a malformed digit string before it reaches a form — not a substitute for confirming international reachability, which needs a real call attempt.

phone number FAQ
Can a foreign phone actually dial a North Korean mobile number?
Rarely. Most domestic mobile subscribers on North Korea's Koryolink network cannot make or receive international calls at all — only a small set of lines used by foreign visitors, diplomats, and state institutions connect across the border, even though every number still follows the standard +850 E.164 shape.
What network do North Korean mobile numbers belong to?
Almost all of them sit on Koryolink, a 3G network launched in 2008 as a joint venture between Egypt's Orascom Telecom and the state-run Korea Post and Telecommunications Corporation, which has since become the country's dominant mobile operator.
Does a valid check confirm the number is actually reachable?
No. It only confirms the 10 digits match North Korea's real numbering plan — not that the line can receive an international call, which for most domestic subscribers it simply cannot.
