How to call a US toll-free (1-800) number from abroad

Airlines, banks, insurers, government agencies and online stores in the US publish a toll-free number as their main phone line. From abroad, that number is often the one you can’t reach: the call fails, drops after a message, or gets billed as an expensive international call. Here is what is going on and what actually works.

The seven US toll-free prefixes

A US toll-free number starts with one of seven three-digit codes: 800, 888, 877, 866, 855, 844 or 833. They are not interchangeable - 1-800-555-0100 and 1-888-555-0100 are two different lines, so dial exactly the code the company publishes.

Why toll-free numbers fail from abroad

• On a toll-free call the company pays for the call, not you. That arrangement only exists inside the North American phone network (the US, Canada and some Caribbean countries).
• Many foreign carriers can’t route +1 800 numbers at all, so the call never connects.
• When the call does go through from a foreign phone or while roaming, it is not free: you pay international or roaming rates.
• Some companies block calls that arrive from outside the US to their toll-free lines to avoid paying for them.

Three ways that work

• Your US phone with Wi-Fi Calling: if you have a US mobile line whose carrier supports Wi-Fi Calling abroad, calls to US numbers over Wi-Fi are often free. Check your carrier’s terms before relying on it.
• The company’s international number: many businesses list a regular (non-toll-free) number for callers outside the US, usually in the "contact us" page or on the back of a card.
• Call over the internet with Hyallo: Hyallo connects to all seven US toll-free prefixes from your browser at our lowest rate, $0.02/min - even an hour on hold costs about $1.20.

Type +1, then the ten digits: +1 800 555 0100. If the number is written with letters, like 1-800-FLOWERS, convert them using the phone keypad (ABC = 2, DEF = 3, GHI = 4, JKL = 5, MNO = 6, PQRS = 7, TUV = 8, WXYZ = 9). Once you are connected, the in-call keypad lets you press the menu options ("press 1 for billing"), exactly as on a normal phone.

One honest caveat: a few companies restrict their toll-free line to certain US regions. If a number doesn’t connect, you are not charged for it - unanswered calls are free - and the company’s regular number is the next thing to try.
