Phone Number Checker: Validate, Format & Find Country

Check phone numbers in bulk. Paste one number or a hundred thousand and get one clean row per number: valid or not, which country it belongs to, mobile or landline, and the properly formatted version ready for dialing or SMS.

Built for sales and marketing teams cleaning CRM lists before calling or SMS campaigns, e-commerce stores validating checkout numbers, and anyone importing leads. Bad numbers waste dialer time and SMS credits; this removes them first. Works for every country, using the same numbering rules Android phones use to recognise numbers.

What you get for each number

• valid: true or false by the country's official numbering plan
• country and countryName: where the number belongs (US, KE, IN...)
• type: mobile, landline, toll free, premium rate, voip and more
• e164 / international / national: clean formats for dialers, SMS gateways and display

Example output

{
  "input": "0722123456",
  "valid": true,
  "country": "KE",
  "countryName": "Kenya",
  "countryCallingCode": "+254",
  "type": "mobile",
  "e164": "+254722123456",
  "international": "+254 722 123456",
  "national": "0722 123456"
}

Numbers without the + prefix

Set the default country and local formats work too: 0722123456 with default country KE parses as a Kenyan mobile, (415) 555-2671 with US as a San Francisco number. Numbers that already start with + ignore the default.

What this does and does not check

It validates that a number is real by structure: correct length, a real country code, an allocated range, and the line type that range belongs to. That catches typos, fakes and impossible numbers — the bulk of dirty data. It does not dial the number or ask the carrier whether the line is active right now; that requires paid carrier lookups. The same honest split as our Email List Checker, which validates deliverability signals without sending mail.

Pricing

$0.002 per checked number (valid or invalid — both are answers). Text that is not a phone number at all is free, and the first 2 rows of every run are free. Cleaning a 10,000 contact CRM export costs about $20, versus per-lookup pricing on carrier APIs that runs 3 to 10 times higher.

Frequently asked questions

How accurate is mobile vs landline? It comes from the official number range allocations each country publishes. In some countries (like the US) certain ranges serve both, reported as "landline or mobile".

Does it find the carrier or owner name? No. Carrier and caller-ID data require paid lookups and are out of scope. Country, type, validity and formatting are what list cleaning needs.

My numbers are a mix of countries without + prefixes. Split them by country and run once per batch with the right default country, or add prefixes first. Numbers with + always work in one run.
