How to Call United States From the US
To call United States from the United States, dial 011 + 1 + area code + local number from a US landline, or +1 + area code + local number from a mobile phone. Drop the leading 0 from the local number. Kinvo connects any United States number from your browser at $0.30/min — no app, no subscription. For the dialing code itself and number-format reference, see the United States country code page.
The United States uses the North American Numbering Plan (NANP), shared with Canada and 18 Caribbean nations. Every US number is 10 digits — a 3-digit area code plus a 7-digit local number — and mobile numbers use the same area codes as landlines. When calling the US from abroad, dial +1 followed directly by the 10-digit number; there is no trunk prefix to remove.

011 is the US international exit code. 1 is United States's country code. On a mobile phone, replace 011 with + (hold the 0 key).

How to Call United States From iPhone, Android, or a Landline
From an iPhone
Open the Phone app, press and hold 0 until a + appears, then type 1 followed by the local United States number. Or use Kinvo in Safari — no dialer permissions needed.
From Android
Open your Phone app, long-press 0 to get +, then dial +1 + the number. In Chrome, open kinvophone.com and call directly without touching your carrier plan.
From a US Landline
Landlines don't have a + key, so use the full exit code: 011 1 then the local number. Check with your phone provider that international calling is enabled to avoid blocked calls.
How to Call United States For Free
If the person you're calling in United States has a smartphone with internet access, the cheapest way to call them is free: use WhatsApp, FaceTime, Telegram, Signal, or Google Meet. Both sides need the same app, and calls travel over the internet rather than the phone network — no per-minute fees, no country code needed.
For calling any regular United States landline or mobile number — the kind that requires dialing +1 — there is no truly free option, because someone has to pay the termination fee to connect the call. Kinvo is the lowest-cost option for dialing United States phone numbers, starting at $0.30/min with no subscription, compared to $1–$3/min at most US carrier rates.
United States Calling Tips
The US spans six time zones, so check the local time before calling. Dial +1 followed by the 10-digit number (area code + local number). Toll-free numbers (800, 888, 877) are not supported via VoIP. Cell and landline rates are the same for US destinations.
