Acceptable use policy

Last updated 15 October 2026

This is a draft. A lawyer has not reviewed it yet, and it names no legal entity or governing law.

1. No stalking and no harassment

Do not use NumberLookup to find, follow, watch, contact or pressure a person who does not want to be contacted, or to help anyone else do so. NumberLookup returns no names or addresses, and you may not use what it returns to work them out some other way.

Do not use results to contact people in ways the law forbids, such as calling or texting someone without the consent you need.

2. No use for any FCRA purpose

NumberLookup is not a consumer reporting agency, and its results are not consumer reports. Do not use them, alone or with other information, to decide whether someone gets credit, insurance, a job, a place to live or any other benefit the US Fair Credit Reporting Act covers.

3. No tampering with the service

Do not get around rate limits or billing, probe the service for weaknesses, or scrape our pages or API to rebuild our data. Do not share a key outside the business that owns the account.

4. Breaking this policy closes the account

If we find or reasonably suspect a breach, we may suspend or close your account straight away. We will tell you why unless the law or an investigation stops us.

5. Reporting abuse

If you think someone is using NumberLookup against this policy, tell us what you saw. Write to support@numberlookup.io. We review every report, though we may not be able to tell you what we did about it.
