International toll-free numbers explained

What is an international toll-free number?

It is a number that callers in more than one country can dial without paying for the call, or while paying only a local rate. The company that owns it covers the cost. There are three standard kinds: a Universal International Freephone Number on country code +800, an International Shared Cost Number on +808, and an international freephone service bought separately in each country, with a local-format number in each.

There is a fourth, practical answer that most people actually need: the company's own regular number for overseas callers. It is not toll-free, but it is published for callers abroad. I cover it further down.

What is a +800 UIFN number?

A UIFN, or Universal International Freephone Number, is one toll-free number that works in several countries at once. It is the country code 800 followed by an 8-digit subscriber number, 11 digits in total, and it is the same in every country where it is switched on ^[1]. The ITU assigns them under Recommendation E.169.1 ^[2].

You dial the international exit code first, then 800, then the 8 digits ^[1]. There is no 1 and no country code for the US, because +800 is itself a global code.

A +800 number only rings in the countries the company paid for. ITU assigns these numbers only to services used in two or more countries, and each must be in service in at least two countries within 180 days of reservation ^[1]. So a +800 number printed on a card can work in Germany and fail in Mexico. Check the company's list of countries before you dial.

What is a +808 shared-cost number?

A +808 number is the shared-cost sibling of +800. The caller pays roughly what a national call would cost in their own country, and the company pays the rest ^[3]. The format mirrors +800: country code 808 plus an 8-digit subscriber number, dialed after your exit code. From the UK that looks like 00 808 5550 0142.

The useful point for a caller: a +808 number is not free, even from a landline. The ITU describes the charge as equivalent to a national call in the country you call from ^[3]. On a mobile, check your carrier's rate for the 808 code before a long call.

What is ITFS (international toll-free service)?

ITFS is the country-by-country model. Instead of one global number, the company rents a local freephone number in each country it serves, and calls are carried back to its call centre. The ITU standard behind it is E.152, 'International freephone service' ^[5]. For callers this looks like an ordinary local freephone number, with a different number in each country.

Telecom operators push this model for cross-border customers. Maxis in Malaysia, for example, tells businesses to use ITFS or UIFN, not a domestic 1800 number, for international customers ^[8].

Real examples from company sites

• American Airlines lists 000-800-0501-944 for India ^[9]. That is India's international toll-free series, not a domestic 1800 number.
• Wells Fargo says customers abroad can call it toll-free from most countries, and gives +1 775 335 1115 for when mobile toll-free calls are blocked; that call is charged to your phone ^[10].
• State Bank of India lists international toll-free numbers for 21 countries, plus a paid +91 number ^[11].

The pattern is the same each time: the number you dial depends on where you are standing, so always take it from the company's own list for your country.

What is India's 000800 series?

India keeps international toll-free numbers in a separate series that starts with 000800. It is assigned by India's Department of Telecommunications and is not the domestic 1800 range ^[4]. A foreign company that wants Indians to call it for free rents a 000800 number; an Indian company's 1800 number is for callers inside India.

Two practical points. On Indian mobiles, the 000800 series needs international dialing (IDD) to be enabled ^[12]. And it is dialed from inside India: it is how Indians reach a foreign company, not how you reach India from abroad. For that direction, see calling Indian 1800 numbers from abroad.

How does a country list work? The 1 800 O-Canada example

Governments use the same model. The Government of Canada runs 1 800 O-Canada for callers at home and publishes a separate list of country-specific toll-free numbers for callers abroad, with the instruction to dial each number exactly as shown ^[13]. For Australia, the listed number is 0011 800 622 6232 1 ^[13].

Read that string closely. 0011 is Australia's exit code ^[7], and 800 followed by eight digits is the +800 format ^[1]. So the Australian entry is a global freephone number, dialed the way the ITU describes.

The lesson for any caller abroad: when a company or government has an international list, use it, and dial the number for the country you are in. For countries not on its list, Canada points callers to the closest Canadian embassy or consulate ^[13].

Why do many US companies list a regular +1 number instead?

Because it is simpler. A regular US number with an area code is not tied to an Area of Service, while a 1-800 line accepts only the areas its owner chose ^[6]. From abroad, the regular number is an ordinary international call. So many banks and agencies skip international toll-free numbers and publish a +1 number for overseas callers. Some take collect calls, which the company pays for.

Social Security's entry is telling. It is a US toll-free number meant for callers abroad, and the agency still warns that local carriers may charge ^[17]. More brands are on customer service from abroad.

Is a US 1-800 number an international toll-free number?

No. A US 1-800 number belongs to the North American Numbering Plan, and its reach is set by the owner's Area of Service: US, Canada, the Caribbean or combinations of those ^[6]. Nothing in it covers Europe or Asia. AT&T says that from outside the US and Canada, toll-free numbers may not connect or may be billed as international calls ^[18].

If you need to reach a US 1-800 line from abroad anyway, the dialing steps, costs and fallback routes are on how to call a 1-800 number from abroad.

Do other countries' 1800 and 0800 numbers work from abroad?

Mostly not, and none is promised. These are domestic freephone numbers, built for callers inside the country. Ireland's regulator says Irish 1800 numbers are not generally internationally accessible ^[19]. Telstra says its 1800 Freecall reverse charging is not available outside Australia ^[20]. UK rules that make 0800 free do not cover calls from abroad ^[21].

In each case, the company's regular number with a country code is the safer route.

How can you tell which kind of number you have?

Look at the first digits after the plus sign or exit code. +800 is the global freephone code. +808 is global shared cost. +1 800, 833, 844, 855, 866, 877 or 888 is North American toll-free ^[23]. A local-looking freephone number that changes by country, such as India's 000800, is per-country international freephone. Anything with a normal area code is a regular number, dialed from abroad as an ordinary international call.

• +800 5550 0142: global freephone, works only in the countries the company enabled.
• +808 5550 0142: shared cost, you pay about a national rate.
• +1 800 555 0142: US or Canadian toll-free, often refuses foreign callers.
• +1 267 941 1000: a regular US number (the IRS line for callers abroad ^[14]), billed at your carrier's international rate.

The 855 code deserves a warning: +855 alone is Cambodia ^[24], while +1 855 is US toll-free. Do not drop the 1.

Is an international toll-free number free from a mobile?

Not always. The company pays its share, but mobile networks may block or charge these calls. Wells Fargo tells customers to call +1 775 335 1115 if mobile toll-free calls are blocked, and warns that such calls are charged to the phone ^[10]. It also notes that Mexico's Telcel blocks international toll-free calls ^[10]. In India, the 000800 series needs IDD enabled on mobiles ^[12].

If the call matters and you are on a mobile, try a landline first, or use the company's collect number where it offers one. For emergencies, none of this applies: use a local phone and the local emergency number.
