Phone and Email Verification

Phone Verification

The Phone Verification module uses the Python phonenumbers library.

It validates telephone numbers using numbering-plan information.

How to Use

1. Open VerAI.
2. Enter a US phone number.
3. Submit the number.
4. Review the validation result.

Supported Input

The supplied implementation accepts US numbers after removing formatting characters.

Examples use fictional telephone numbers.

Phone Validation Checks

The application performs two main checks.

Possible Number

Determines whether the number's structure is possible under the library's numbering rules.

Valid Number

Determines whether the number belongs to a recognized, valid numbering range according to the library's metadata.

Both checks must succeed for the number to be accepted.

Returned Information

For a valid number, VerAI returns:

Limitations

Phone verification does not establish:

• Whether the number is currently active
• Whether someone can receive calls or texts
• Whether the number is associated with a particular person
• Whether a call or message is fraudulent
• Whether the caller ID has been spoofed

Although the source imports carrier-related functionality, the active phone analysis does not return a carrier lookup.

The supplied module also does not implement a live carrier or subscriber verification service.

Email Verification

The Email Verification module inspects infrastructure associated with the domain portion of an email address.

How to Use

1. Enter an email address.
2. Submit the address.
3. Review MX record information and domain age.

Example

[email protected]

VerAI extracts:

example.com

and analyzes that domain.

MX Record Lookup

Mail Exchange (MX) records identify servers responsible for receiving email for a domain.

Example

10 mail.example.com
20 backup.example.com

The values above are illustrative.

Returned Information

The module returns available MX records or a lookup error.

An MX record generally indicates a configured mail-routing destination.

It does not establish that a particular mailbox exists.

Domain Age

VerAI queries WHOIS information and attempts to determine the domain's creation date.

It calculates an approximate age in days.

Example

Domain Age: 1200 days

This is an illustrative result.

Interpretation

Domain age can provide useful background information.

A newly registered domain is not necessarily malicious, and an old domain is not necessarily trustworthy.

Established domains can be compromised or repurposed.

Email Verification Limitations

The module does not perform:

• SMTP mailbox verification
• Email ownership confirmation
• Deliverability testing
• SPF validation
• DKIM validation
• DMARC validation
• Email message analysis
• Sender identity verification

It also uses basic string splitting to extract the domain, rather than a complete standards-compliant email address parser.

Comparison

Responsible Use

Phone and email analysis should be treated as supporting metadata.

Do not use these results alone to accuse individuals or organizations of fraud.

Important: VerAI verifies limited technical properties of phone numbers and email domains. It does not authenticate their owners.
