Bulk Phone Number Lookup — Phone Validator & Reverse Phone

Paste a list of phone numbers, get a full verdict on every one. This bulk phone number lookup and phone validator turns a messy column of numbers — (415) 555-2671, 001-415-555-2671, +82 10-1234-5678 — into clean, decision-ready rows: valid or invalid, what kind of line it is, which country and carrier range it belongs to, what time zone the owner is in, all four standard formats, whether you can send it an SMS, and what to watch out for.

Powered by libphonenumber, the same numbering-plan library that ships inside Android — running fully offline on the Apify platform, with API access, scheduling, integrations and monitoring built in.

Unofficial. This Actor uses the open-source libphonenumber metadata (Apache-2.0, via the phonenumbers Python port) and is not affiliated with, endorsed by, or sponsored by Google or any carrier. See LICENSE-NOTICE.md.

Why use Bulk Phone Number Lookup?

• Bulk, not one-at-a-time — hand it a whole list; every number comes back as its own row, plus one batch summary row at the end.
• A verdict, not a boolean. Most validators answer true / false. This one answers in a sentence you can paste into a ticket: +82 10-1234-5678 — valid South Korea mobile, Asia/Seoul, safe to SMS
• Line type, so you know what you are calling — mobile, fixed line, VoIP, toll-free, premium rate, shared cost, pager, UAN, voicemail.
• Risk flags — premium-rate, voip, shared-cost, toll-free, not-possible, invalid-for-region, country-mismatch, unparseable, rolled into a single riskLevel of none / low / medium / high. Premium-rate numbers in a lead list are a cost trap; this is the field that catches them.
• SMS-capability — smsCapable is true for mobile lines, false for fixed lines and service numbers, and null when the plan genuinely cannot tell (VoIP, personal numbers). Filter your SMS campaign on one field.
• Reverse phone data — country, country name, international dialling code, geographic region (San Francisco, CA, London), carrier range (Vodafone, T-Mobile) and IANA time zones, all from public numbering-plan metadata.
• Four formats at once — E.164 (+14155552671), international (+1 415-555-2671), national ((415) 555-2671) and RFC3966 (tel:+1-415-555-2671), so the output drops straight into your CRM, dialler or SMS gateway.
• Duplicate collapsing — 415-555-2671 and +1 415 555 2671 are the same line; with dedupe on (the default) you get one row, not two.
• Offline and private — no API keys, no third-party service, no lookup request leaves the run. Your list is never sent anywhere.

How to use Bulk Phone Number Lookup

1. Paste your numbers into Phone numbers.
2. Set a Default region (e.g. US, GB, KR) if some numbers have no country code.
3. Click Start and read the results in the Output tab, or pull them through the Apify API.

Input

Field	Type	Description
phoneNumbers	array	The numbers to check. Any format.
phoneNumber	string	Single-number alternative.
defaultRegion	string	ISO 3166-1 alpha-2 code used for numbers with no country code (e.g. US).
dedupe	boolean	Collapse numbers that normalise to the same E.164 value. Default true.

{
  "phoneNumbers": [
    "+1 415-555-2671",
    "+82 10-1234-5678",
    "+44 20 7183 8750",
    "+49 1522 3433333",
    "+1 900 555 0199"
  ],
  "defaultRegion": "US",
  "dedupe": true
}

Output

One dataset item per phone number. Rows that carry a noticeCode are status rows, not results (summary, no-input, targets-truncated, charge-limit-reached, free-plan-cap, billing-unavailable) — skip them when parsing programmatically.

Invalid input ends the run as SUCCEEDED with a notice row.

}

The batch also gets one unbilled summary row with numbersReceived, numbersAnalysed, duplicatesRemoved, validCount, invalidCount, smsCapableCount, and the full countryDistribution, typeDistribution and riskFlagDistribution.

You can download the dataset in various formats such as JSON, HTML, CSV, or Excel.

Data table

Field	Description

e164 / international / national / rfc3966	The four standard formats
numberType / numberTypeLabel	Line type code and human label
country / countryName / countryCallingCode	ISO code, country name, dialling code
region	Geographic area the number range belongs to
carrier	Carrier that holds the number range, where the plan records one
timezones	IANA time zones for the number range
smsCapable	true / false / null when the plan cannot tell
riskFlags / riskLevel	What to watch out for, and how serious
invalidReason	Why a number failed, in plain English
normalization	What changed between your input and E.164
scannedAt	UTC timestamp of the check

Pricing

Pay-per-event: $0.005 per run plus $0.03 per number resolved. A list of 100 numbers costs $3.005 for that run. Every number written to the dataset is charged, whether the verdict is valid or invalid — an "invalid" verdict is the answer you asked for, and it is the one that saves you a wasted SMS. Batch summary and status rows are not charged. Apify platform compute is billed separately per your plan.

Free-plan runs return up to 25 numbers; upgrade your Apify plan to receive the full result set in one run.

Tips

• Set defaultRegion to the country your list mostly comes from — numbers without a country code are unparseable otherwise.
• Filter on smsCapable == true before an SMS campaign, and on riskLevel in ("medium", "high") before a dialler campaign.
• country-mismatch catches numbers that claim one country but belong to another — a common signal in fraud screening.
• Schedule a recurring run against an exported CRM segment to keep contact data clean over time.

FAQ, disclaimers, and support

Does it tell me who owns the number? No. This Actor returns numbering-plan facts — validity, line type, country, region, carrier range, time zone — not subscriber identity. No personal data is looked up or returned.

Does it tell me whether the number is currently in service? No. Offline validation says the number is well-formed and issuable under the public numbering plan. Live line-status checks require a paid HLR lookup, which this Actor deliberately does not perform.

Why is carrier empty for some numbers? Carrier data exists only for mobile ranges in countries that publish it, and number portability means the range holder is not always the current carrier. Treat it as a strong hint, not a guarantee.

Privacy & data responsibility. You are the data controller for every number you submit; ntriqpro is a data processor acting solely on your instructions. Validation runs offline inside your own run and we do not store your results — output is written only to your own run's dataset. You are responsible for a lawful basis and for complying with GDPR, PIPA, CCPA, TCPA and other applicable laws.
