South Sudan Phone Number validator
How the phone number format works
- Format
- South Sudan phone number in national or international (+211) format
- Example
- +211977123456
Things to watch for
- Accepts national or international (E.164, e.g. +211...) 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 South Sudan phone number is 9 digits under the country code +211, almost always a mobile number given how little of the network was ever built on legacy landlines. South Sudan is Africa’s newest country, having seceded from Sudan on 9 July 2011 following a referendum that ended decades of civil war — a young-enough nation that its phone numbering plan, with its own dedicated +211 code, was assigned from scratch rather than inherited or split from Sudan’s existing +249.
How this validator works
Enter the number in national form (977123456) or full international form (+211977123456); this tool checks the 9-digit length and mobile-prefix pattern against South Sudan’s real numbering plan using Google’s libphonenumber, entirely client-side. Because the country’s mobile networks expanded rapidly after independence, the validator’s prefix ranges reflect a newer, mobile-only plan rather than the older mixed landline-and-mobile patterns seen in longer-established countries.
What a pass doesn’t tell you
A pass confirms the number matches a real South Sudanese mobile shape — it doesn’t confirm the SIM is active or currently in service, given how young and fast-changing the country’s telecom infrastructure still is.
Scope: useful for catching a missing digit or a wrong country-code assumption before a South Sudan number reaches a form — not proof of reachability.

phone number FAQ
Why does South Sudan have its own country code instead of sharing Sudan's?
Because South Sudan became a fully separate country. It seceded from Sudan on 9 July 2011 after a referendum, making it the world's newest UN member state at the time, and the ITU assigned it a fresh code, +211, rather than reusing any part of Sudan's +249.
Does South Sudan have widespread landline phone coverage?
No. Like many countries that built out telecoms after 2000, South Sudan's network is overwhelmingly mobile-first — legacy fixed-line infrastructure was never built out at scale, so a phone number there is almost always a mobile one.
Does a valid check confirm a South Sudan number is currently active?
No. It only confirms the 9 digits match a real South Sudanese mobile pattern — not that the SIM is active or reachable, which needs a carrier-side lookup this tool doesn't perform.
