United States phone numbers — common questions
What is the country code for United States?
The international dialling code for United States is +1. A virtual United States number is issued inside that numbering plan, so it appears as a local number to anyone calling or texting from within the country.
Can I receive SMS on a United States number?
Yes. Incoming SMS arrives instantly and can be read in the platform, delivered into 3CX, or pushed to your own server through a real-time webhook. Two-way conversations run on the same number.
Do I need an office in United States to get the number?
No. The number is virtual — it routes to your existing 3CX system or SIP setup wherever your team works. You manage it from the browser.
Can I use a United States number for calls as well as SMS?
Yes. The number handles inbound and outbound calls plus SMS in both directions, and can also receive WhatsApp audio and video calls routed into your system.
