From another country, dial your exit code, then +1 (United States), then IRS's support number — you'll find the current number on IRS's official contact page. TwinPhone handles the dialing format for you: open the dialer in your browser, paste the number and call. No SIM swap or roaming needed.
IRS's customer-service line is based in United States, so it uses country code +1. Add your own exit/international-access code before it when calling from abroad.
With TwinPhone, calls to United States numbers start from $0.02/min — pay-as-you-go, no subscription. That's far cheaper than roaming or hotel-phone surcharges when you're stuck on hold with support.
Always use IRS's official contact page (linked on this page) for the current, correct number — support lines change and we don't publish unverified numbers. Once you have it, call it cheaply from your browser with TwinPhone.
