Alternatives / 1lookup
A 1lookup alternative that starts at $19
TrustLookup and 1lookup charge the same credits for the core checks. TrustLookup has a free plan and smaller paid plans; 1lookup has a far bigger catalog of enrichment data.
The short version
Pick TrustLookup if
- You need phone, email, IP or domain checks and fewer than 20,000 credits a month.
- You want a free plan to build against, with no trial clock.
- You want VIN, NPI and USDOT lookups at no cost.
Stay with 1lookup if
- You need enrichment: reverse phone, skip tracing, B2B contact data, firmographics or sanctions screening.
- You want ready-made Zapier, Make, n8n, Google Sheets or CRM integrations.
- You run more than a million credits a month and want an enterprise plan with a dedicated contact.

Switching takes one request
Send the value to /v1/lookup and name the checks you want; TrustLookup works out whether it’s a phone number, email, IP or domain. One request can run several checks, and the response has one summary and risk score.

Do the credits cost the same?
For the core checks, yes: phone, email and IP checks are 1 credit, portability 3 and HLR 5 on both. The difference is the price of a credit and the size of the smallest plan.
Does TrustLookup do reverse phone lookups?
No. TrustLookup checks numbers and their networks, not the people behind them.
Is there a free version?
Yes. The free plan has 250 credits every month with no time limit, and the free carrier lookup page needs no account.
