How to Dial 800 Number From Mexico: A Comprehensive Guide

Calling international numbers can be confusing. Each country has its own exit codes, country codes, and number formats. If you don’t follow the correct sequence, your call might fail or cost more than expected, especially when trying to reach toll-free numbers.
If you're in Mexico and trying to call a US 800 number, the process is different from dialing local numbers. You need to use Mexico’s exit code, the US country code, and replace the 800 prefix with a special code. This guide will walk you through exactly how to dial US toll-free numbers from Mexico. We’ll also briefly cover how to call 800 numbers in other countries like the UK and Australia.
What is an 800 Phone Code?
An 800 phone code is a type of toll-free number prefix used in telephone numbering systems, mainly in the US and Canada. It allows people to call businesses without paying for the call. These numbers are often used for customer service, sales, and support.
The standard format of a US toll-free number is 800-XXX-XXXX. Other toll-free prefixes like 888, 877, 866, 855, 844, and 833 work the same way and are used when 800 numbers are already taken.
Steps to Call 800 Number From Mexico
As stated earlier, 800 numbers are toll-free numbers. Calling the 800 number is free for the caller, while the company you are calling pays for it.
The general steps to call the 800 number from Mexico are:
- Step One: Dial Mexico’s exit code.
- Step Two: Dial the country code you are trying to connect.
- Step Three: Enter the 800 prefix.
- Step Four: Enter the rest of the number.
Note: If you are dialing from a landline, dial 00 (Mexico's exit code), but if you are dialing from a mobile, you can dial ‘+’ instead of 00.
Remember: You must dial the 800 prefix, considering the country-specific toll-free number. For instance, input the 1800 code while dialing an Australian toll-free number from Mexico.

How to Call a US 800 Number from Mexico (Step-by-Step Format)
US toll-free numbers like 800, 888, or 877 won’t connect directly from Mexico. To call these numbers, replace the prefix with the correct code and use the proper international dialing format. Follow these steps to make your call successfully:
- Step 1: Dial Mexico’s exit code → 00 (from landline) or + (from mobile)
- Step 2: Enter the US country code → 1
- Step 3: Replace the 800 prefix with the correct code (see table below)
- Step 4: Dial the remaining 7 digits of the toll-free number
For Example:
If you dial a toll-free number in the U.S. as '800-xxx-xxxx', a caller in Mexico will dial 001-880-xxx-xxxx.
Calling 800 UK Number
To dial 800 UK numbers from Mexico, dial Mexico’s exit code, the UK’s country code, toll-free prefix, and the receiver’s number. Here are the steps to call 800 UK number:

- Step Two: Enter the UK country code (44).
