Northern Mariana Islands area code · 670
The CNMI's 670 — one code for Saipan, Tinian, and Rota.
The Commonwealth of the Northern Mariana Islands operates on a single area code: 670. It covers all inhabited islands — Saipan (the capital and commercial center), Tinian (site of major US Air Force expansion), and Rota (the southernmost main island). The CNMI shares the Chamorro Standard Time zone with Guam (UTC+10) and does not observe daylight saving time. A local 670 on Ringflow gives your business genuine CNMI presence — recognized by military contractors, Asia-Pacific investors, and government agencies throughout the Commonwealth.
