How do I know if a phone number is valid?

A valid phone number follows the correct format for its country, has the right number of digits, and uses a valid area/mobile code. Our validator checks all these factors instantly. Enter any number with the country code (like +1 for US) to verify.

What does line type mean?

Line type indicates whether a number is a mobile phone, landline (fixed line), VoIP (internet phone), toll-free, or other types. Mobile numbers are cell phones, landlines are traditional home/office phones, and VoIP numbers use internet calling services.

Can I validate international numbers?

Yes! Our validator supports phone numbers from 240+ countries worldwide. Just enter the number with its country code (e.g., +44 for UK, +91 for India) or select the country manually for numbers without the + prefix.

Is this phone number real or fake?

Our validator checks if a number follows the correct format and structure for its country. However, we cannot verify if someone actually uses the number. A 'valid' result means the format is correct, not that the number is actively in use.

What is E.164 format?

E.164 is the international standard format for phone numbers. It starts with +, followed by the country code and phone number with no spaces or special characters. Example: +14155551234. This format is used by most phone systems and APIs.

How accurate is phone number validation?

Our validation is highly accurate for format checking, using the official numbering plan data for each country. We verify country codes, area codes, number length, and phone type. However, we cannot confirm if a number is currently in service.

Can you detect the carrier or mobile provider?

We can detect the line type (mobile, landline, VoIP) based on the number prefix. However, due to number portability (people keeping their number when switching carriers), we cannot reliably determine the current carrier.

Why does my valid number show as invalid?

Common reasons include: missing country code, extra digits, wrong area code, or special characters. Try adding the country code with + (like +1 for US) and removing any spaces, dashes, or parentheses.

How Phone Number Validation Works

Format Verification

We check if the number follows the correct format for its country, including proper country code, area code, and digit count.

Country Detection

The country is automatically detected from the country code prefix (e.g., +1 for US/Canada, +44 for UK).

Line Type Detection

Based on the number prefix, we identify if it's a mobile, landline, toll-free, VoIP, or other type of number.

E.164 Standardization

Valid numbers are converted to E.164 format, the international standard used by phone systems worldwide.
