Best reverse phone lookup services, scored
Services that start from a phone number and return who or what is behind it. 6 vendors ranked from pages read between 2026-10-18 and 2026-10-19.
How the scores work
Each product scores out of 100, from the vendor's own read record only: published terms 30, lowest price per 1,000 30, plans or packs priced 20, billing without a monthly minimum 20.
| Criterion | Weight | How it is computed |
|---|---|---|
| Published terms | 30 | Share of the 7 comparison terms (free option, free trial, credit expiry, contract minimum, API access, rate limits, support) that the vendor's own page states, times 30. |
| Lowest price per 1,000 | 30 | The lowest per-1,000 figure in US dollars in the vendor's price rows: printed on the page, or our arithmetic from a price per request. The cheapest on the list scores 30, the dearest scores 0, and the rest fall between them on a log scale. A vendor with no dollar per-1,000 figure, including one that prints its prices in another currency, scores 0 on this criterion. |
| Plans or packs priced | 20 | Price rows printed on the vendor's pages: three or more score 20, fewer score a proportional share. |
| Billing without a monthly minimum | 20 | Prepaid credits or per-request billing score 20, a mix of packs and subscriptions scores 10, and subscription, per-seat or quote-only billing scores 0. |
