Telephone numbers in Samoa follow a national numbering plan administered by the Samoa Communications Authority. The plan conforms to the International Telecommunication Union (ITU) recommendations and is used for both fixed‑line (landline) and mobile services.
Country code and international dialing
- Country code: +685
- International call prefix (to dial out of Samoa): 00
National Numbering Structure
- National Significant Number (NSN) length: 5 digits for all services.
- No trunk prefix is used; callers dial the full 5‑digit number directly for domestic calls.
Number ranges
| Service type | Leading digits (prefix) | Example format |
|---|---|---|
| Landline (fixed) | 20, 22, 23, 24, 25, 26, 27, 28 | 20 1234 |
| Mobile | 51, 52, 53, 54, 55, 56, 57, 58, 59 | 52 5678 |
| Special / non‑geographic | 70, 71, 72, 73, 74, 75, 76, 77, 78, 79 | 71 0000 |
- The specific prefixes allocate numbers to particular service providers and geographic areas, though the country is small enough that geographic distinctions are limited.
- Mobile prefixes (51‑59) are primarily assigned to the two main mobile operators: Digicel Samoa and Samoa Telecommunications Corporation (STC).
Dialing examples
- Calling a Samoan landline from abroad: +685 20 1234

- Calling within Samoa (mobile to mobile): 52 5678
Number allocation and administration
