THE CONCEPT
What Is a UIFN (00800) Number?
A UIFN, or Universal International Freephone Number, is a single toll-free number that callers in 60+ participating countries can dial for free. It is often called a 00800 number: “00” is the international access code used in many countries, and “800” is the code the ITU assigns to international freephone service.
Managed under ITU rules, a UIFN uses the globally standardised +800 country code, giving businesses a single 11-digit number (+800 XXXX XXXX) that is accessible from multiple countries.
As a universal free call number, the receiving business covers all call costs, making it free for customers to reach you from any participating country.
How to Dial a 00800 Number
Callers dial their country’s international access code, then 800, then the 8-digit UIFN. For example:
• Most of Europe and many other countries: 00 800 XXXX XXXX
• US and Canada: 011 800 XXXX XXXX
• Australia: 0011 800 XXXX XXXX
• From a mobile phone, +800 XXXX XXXX works the same way

FAQ
UIFN 00800 Number FAQs
What exactly is a UIFN number?
A Universal International Freephone Number (UIFN) is a single toll-free number that works across 60+ participating countries as part of a unified freephone service. Whether your customers call from a mobile phone or landline within our 60+ country coverage area, they will never face a long-distance charge. It is the ultimate universal free call number for global brands.
What does 00800 mean, and what is the 00800 country code?
00800 combines “00”, the international access code used in many countries, with “800”, the code the ITU assigns to universal international freephone service. Callers in countries with a different access code dial that code instead, such as 011 from the US or 0011 from Australia, followed by 800 and the 8-digit number. You can also dial +800 from a mobile phone.
0800 vs 00800: What’s the Difference?
National 0800 freephone numbers, such as those used in the UK, work only inside one country. A 00800 UIFN is an international freephone number: one number that works across 60+ countries. If you need freephone access for customers in several markets, a UIFN replaces separate 0800-style numbers in each country.
Are 00800 numbers free to call?
Yes. Calls to a 00 800 number are free for callers in all participating countries. This applies to calls made from both landlines and mobile phones, ensuring a frictionless experience for your customers. The business that owns the UIFN pays the call charges.
How much does a 00800 number cost?
Callers pay nothing. For your business, the cost depends on the countries you cover and your expected call volume. M800 offers transparent pricing with no hidden fees, so contact us for a quote based on your target countries.
How does a freephone telephone number differ from regular 800 numbers?
Traditional toll-free services (like 1-800) require a separate number for every country. A UIFN provides one universal number (in the 00 800 format) that works identically across all participating nations, simplifying your international marketing.
What are the benefits of using a UIFN for business?
A freephone business identity eliminates the confusion of multiple prefixes. It enhances accessibility for customers calling from landlines or mobiles, improves brand trust, centralizes your global communication into one easy-to-manage line, and unifies your freephone service across borders.
