Phone Number Validator API: Format, Type & Country

Use when…

• You need to check and format phone numbers (E.164) before saving, texting or calling.
• A CRM, sign-up or data-cleaning agent must tell mobile from landline or VoIP and find the country and time zone.
• You want bulk validation for a tiny per-number price, with no API key.

Clean up and check phone numbers from any country in bulk.

• Valid / possible for that country's numbering plan
• Formats: E.164 (+447911123456), international, national, tel: URI
• Line type: mobile, fixed line, VoIP, toll-free, premium...
• Country, region/city (where the number plan shows it), original carrier, time zones
• Pass country for local-format numbers (07911 123456 + GB)

Quick start

Leave the default input (it is prefilled) and click Start:

{"requests": [{"phone": "+44 20 7946 0958"}, {"phone": "(415) 555-2671", "country": "US"}, {"phone": "07911 123456", "country": "GB"}]}

Send many items in requests per run (cheaper and faster than one run each).

Sample output (real run, 26 Oct 2026, default input)

phone	valid	country_code	e164	national	line_type	location	original_carrier
+44 20 7946 0958	true	GB	+442079460958	020 7946 0958	fixed_line	London
(415) 555-2671	true	US	+14155552671	(415) 555-2671	fixed_line_or_mobile	San Francisco, CA
07911 123456	true	GG	+447911123456	07911 123456	mobile	Guernsey	JT

Each row also has possible, calling_code, international, rfc3966, timezones and a note.

Use cases

• Clean and standardise phone numbers to E.164 before saving them in a CRM.
• Check sign-up or order form numbers are real-looking for that country.
• Split mobiles from landlines before sending SMS.
• Add country and time zone to contact lists so calls happen at sensible hours.

Pricing

Pay per event: $0.001 per phone check (one phone number parsed and validated). Rows with errors are not charged.

Sources and licences

Google libphonenumber via the phonenumbers Python port (Apache 2.0).

Notes

No live network lookup: carrier is the original range holder and the number may have been ported. Validity means the number fits the plan, not that it is switched on.

FAQ

Does it check the phone is switched on? No. It checks the number fits the country's numbering plan. There is no live network lookup.

Do I need an API key? No.

Local numbers like 07911 123456? Add country (e.g. GB) so it knows which country to read them for.

Limits & failure modes

• Valid means the number fits the plan, not that it is live or belongs to the person.
• Carrier is the original range holder; the number may have been ported.
• UK mobile ranges shared with the Crown Dependencies can show as Guernsey or Jersey (as in the sample).
• Location is only as precise as the number plan (often just the country for mobiles).
