In most cases, no. Toll free phone numbers are country-specific. Individual countries have their own set of coverage, restrictions, and accessibility rules associated with toll free numbers. Each country has its own dialing format for toll free numbers, too.

International toll free numbers get their name from their most common use-case, which is forwarding calls made from callers in one country to one or multiple locations abroad. Toll free phone numbers are not guaranteed to work when dialed from abroad. If an international caller is able to connect, they should expect to pay long-distance or international call rates associated with their personal phone service.

Yes you can! Companies looking to use a single toll free number globally can set up a universal international freephone number. But be warned, this is not as simple as it sounds. In fact, UIFNs come with many stipulations and add-on costs that make most companies reconsider their plan of attack.

UIFNs are toll free numbers that can be dialed toll free from as many as 50 countries. Unlike international toll free numbers, UIFNs are regulated by the International Telecommunication Union (ITU). This matters to you because:
The ITU charges vendors a $200 setup fee per UIFN.
The ITU only covers a few dozen countries, so UIFN’s aren’t truly “universal.”
UIFN’s require an international code before the number itself in order to connect. This code is different in each country, and the number format often confuses potential callers.
Your UIFN only works in the countries you are paying a subscription for. These subscriptions are often more expensive than just buying a dedicated toll free number in that country.

That depends on your use-case! More often than not, an international toll free number will be easier to remember and more professional looking than local dial-codes being used for your business. More importantly, local call charges can be very expensive for callers in other countries (looking at you UAE). Here are some examples to consider:
In the US and Canada, callers no longer have to worry about long-distance charges, so which number type you use may just be a matter of preference.
If you want your international company to appear more localized in certain markets, choosing a local area code phone number for your business is a great choice.
In countries like Australia and the UK, non-geographic numbers are also popular for businesses. For example, many nonprofits and government agencies in the UK use non-geographic 03 numbers and companies expanding in Australia may opt for shared-cost 1300 numbers rather than toll free 1800 numbers.
