The preferred spelling in formal U.S. writing is cell phone (two words), as documented by the FCC and Britannica, while cellphone is an accepted variant; no official rule from Apple, Google, or Samsung mandates one over the other.
What the official sources say
FCC materials consistently use "cell phones" and "wireless devices," not "cellphone," in their guidance. Britannica’s entry uses "cell phone" as the head term, defining it as a wireless telephone operating within a defined area. The Associated Press (AP) Stylebook advocates for the two-word form 'cell phone', while The Chicago Manual of Style accepts both variations.
When to use 'cell phone' vs. 'cellphone'
Use cell phone in formal, professional, or U.S.-focused writing, such as business reports, academic papers, and government communications, to match the style of authoritative sources. Cellphone is acceptable in informal contexts like texting, social media posts, or casual conversation, where brevity is valued. For global audiences, mobile phone works well and avoids regional spelling debates. The choice ultimately depends on your audience and the tone of your writing.
Why the confusion exists
Compound words in English often evolve from two words to one over time, as seen with "e-mail" becoming "email" and "on line" becoming "online." Cellphone follows this trend, merging "cell" and "phone" into a single word for convenience. However, "cell phone" remains the dominant form in edited U.S. publications, and the shift to a closed compound has not been as widely adopted as with other terms. The variation persists because language change is gradual, and different style guides and regions favor different forms.
