Terms of service

1. The service

NumberLookup checks phone numbers and IP addresses. For a phone number it returns whether the number can be real, the line type, the carrier, the region and a verdict. For an IP address it returns the country, the network and whether the address is a Tor exit node or sits in a cloud or hosting range. You can check one at a time in the dashboard, send checks through the API, or upload a list.

A verdict describes whether a number can be reached. It is not a compliance check. It does not tell you that you have consent to contact a number, that the number is off a Do Not Call list, or that a call or message is lawful. Those are your responsibility.

Live phone data covers the United States and Canada. Results come from third-party data and public lists. We work to keep them current, but we do not promise that a result is correct or complete.

2. Accounts and API keys

You need an account to use NumberLookup. Give us a real email address and keep your sign-in details to yourself. You are responsible for what happens under your account. Each account has one user.

An API key lets whoever holds it spend your credits. Keep keys on your server, not in a web page or an app you ship. If a key leaks, revoke it on the API keys page. We show a key once and cannot show it again.

3. Credits, purchases and refunds

A check costs 1 credit. These cost nothing: a result of unknown, input that fails the format check, empty input, duplicate rows in a list, private and reserved IP addresses, and any error response. Credits reserved for a list and not used come back to your balance when the list finishes.

You can buy credits as a pack, which is one payment, or on a monthly plan, which adds its credits each time it renews. Credits never expire, whether they came from a pack, a plan or the free credits given at sign-up. Prices are on the pricing page and are charged in US dollars. Stripe takes the payment. We never see or store your card number.

You can cancel a plan at any time from the billing page. It ends at the end of the period you have paid for, you are not charged again, and the credits already on your account stay. We email you to confirm the date.

Purchases are final once the credits are on your account, except where the law says otherwise or where we made a mistake, such as charging you twice or not delivering the credits you paid for. If that happens, write to support@numberlookup.io and we will put it right.

4. Acceptable use

The acceptable use policy is part of these terms. In short: no stalking or harassment, no use for any purpose the US Fair Credit Reporting Act covers, and no tampering with the service. Breaking the policy closes the account.

5. Data and results

You keep your data. You give us the numbers, addresses and files you send so that we can run your checks, and for nothing else. We do not sell them and we do not use them to market anything.

Uploaded files and their results are deleted automatically 30 days after a list finishes. The privacy policy says what else we keep and for how long. IP data is provided by IPinfo and is subject to its licence.

6. Liability

NumberLookup is provided as it is. To the extent the law allows, we are not liable for indirect or consequential losses, lost profit, or anything you do on the strength of a result, including calls or messages you send.

To the extent the law allows, our total liability to you for any claim is limited to the amount you paid us in the 12 months before the claim.

7. Changes to these terms

We may change these terms. We will post the new version here with a new date, and email you when a change affects how you use the service. If you keep using NumberLookup after a change takes effect, you accept it.
