Paste a phone number to see its country, format, and line type — instantly, in your browser.
Used to interpret numbers that don't start with a + and country code.
Enter a phone number above to see its validity, country, and formats.
This tool uses libphonenumber-js — the same phone number library used by Google's Android and Chrome — to validate numbers against real country numbering plans. It converts any input into E.164, international, and national formats, and identifies whether the number is a mobile, landline, VoIP, or other line type. Everything runs locally in your browser; no number is ever sent to a server.
What is E.164 format?
E.164 is the international standard phone number format: a plus sign followed by the country code and national number with no spaces or punctuation, such as +14155552671. It's the format most APIs and databases require.
Why do I need to select a default country?
If you enter a number without a leading +, there's no way to know which country's numbering rules to apply — the same digits can be a valid number in one country and invalid in another. The default country tells the parser which rules to use.
Is my phone number uploaded anywhere?
No. Parsing happens entirely in your browser using JavaScript — the number you enter is never transmitted to LazyParadise or any third party.
Does this tell me who owns the number?
No. This tool only validates format and identifies the country, calling code, and line type (mobile, landline, etc.) — it cannot and does not look up the owner or any personal information.
Why does it say my number is invalid?
The number doesn't match any valid pattern for the selected (or detected) country. Double-check the country code, remove typos, and make sure you've included enough digits.
What does 'number type' mean?
It's the category of line the number is assigned to — such as mobile, fixed-line, VoIP, toll-free, or premium-rate — based on the numbering ranges each country's carriers allocate to those categories.
This tool runs entirely in your browser. The phone number you enter is never uploaded, logged, or sent to any server.
