Hi @Cameron_R,

There are a few levels of validations:

1. 
   

   Whether a phone number fits a particular pattern (Unbounce does this natively, just have to pick the country when you are setting up the phone field)

   
   


2. 
   

   Check if a phone number is “real” - While real can mean different things technically, this type of validation requires a 3rd party API and some custom coding. This API can return a response whether the phone is live/active, whether it’s a landline or a mobile phone, etc.

   
   

Based on the response from #2 above, you can stop the form from being submitted, throw up errors, etc.

Best,

Hristian

Hi,

Not sure if you are still after this but we have a real-time lookup service for phone numbers and have just released an integration guide for Unbounce here: https://www.datasoap.co.uk/intergrations/unbounce

Currently, it works for mobile (cell) phones for most of the world and only landline numbers in the UK.

Cheers,

Bryn

Validating if a phone number is real and determining if it belongs to the United States can be achieved through various methods, but it typically requires custom coding or integrating with third-party services. There's no simple setting or built-in feature in standard HTML or JavaScript that can automatically verify phone numbers in this way.

Here are some common approaches to validate and determine the origin of a phone number:

1. **Regular Expressions (Regex)**: You can use regular expressions in programming languages like JavaScript to validate the format of a phone number. While this can ensure that the number follows a standard format, it won't tell you if it's a real and active number.

2. **Phone Number Validation APIs**: There are third-party services and APIs that specialize in phone number validation. These APIs can check if a phone number is valid, active, and determine its country of origin. Examples of such services include Twilio Lookup, Numverify, and PhoneValidator.

3. **Telecom Database Lookup**: Some telecommunications providers maintain databases that can be queried to verify phone numbers and determine their origin. However, access to these databases may be restricted and require partnerships with the telecom companies.

4. **Reverse Phone Lookup**: Reverse phone lookup services allow you to input a phone number and get information about its owner, location, and possibly its origin country. However, these services might not always be accurate or comprehensive.

5. **SMS Verification**: Another approach is to send an SMS verification code to the provided phone number. If the user receives the code and enters it back, it confirms that the phone number is valid and can receive messages. However, this method only validates if the number is reachable, not if it's necessarily from the US.

It's important to note that phone number validation can be a complex task due to factors like number portability, different phone number formats, and the availability of real-time data. Third-party services that specialize in phone number validation often offer more accurate results and reduce the complexity of custom coding.

If you need this functionality for a specific project, consider exploring phone number validation APIs or services as they can provide reliable results and simplify the implementation process.
