If you have ever "fat fingered" anything, you know that typo's are easy to do when you are in a hurry or working from a small screen. You can relax because Gazelle will validate your phone numbers for you.

How phone number validation work?

It's easy, when a phone number is saved to one of our servers we check it against an international library of phone numbers to validate the Country Code, Area Code, and Prefix are all valid. If not, you will see this error: 

In the example above the phone number is (+1) 704-199-3103. This resulted in an error because the prefix "xxx-199-xxxx" does not match the 704 area code.

  • Country Code +1: for this example the USA Country Code "+1" is hidden in the screenshot because the Gazelle account is located in the USA.
  • Area Code 704-xxx-xxxx: "704" is recognized as a valid US area code
  • Phone Prefix 704-199-xxxx: "199" is not a valid prefix for this region because the 704 area code only uses prefixes between the numbers "200-999". 
  • Phone Number 704-199-3103: The last four digits of every phone number are usually always valid because they commonly use every digit combination between "0000-9999"

What is considered a Valid Number?

A valid phone number is considered a phone number where the combination of the Country Code, Area Code, and Phone Prefix all go together in the real world. For example the area code "101" does not exist inside the USA so the phone number combination of +1-101-xxx-xxxx will trigger the error message.

What is considered an International Number

An "International" phone number is determined by the country listed on your Gazelle Company Profile. Anything different than your default country code is considered an "International" number. 

If your default country code is +1 "USA" than any phone number outside the US will require you to prefix it with the international country code. otherwise Gazelle will automatically save the number with a +1 Country Code.
