Reverse Lookup
Reverse lookup for any US number
Mr. Number can provide a name for more than 90% of US landline numbers and 50% of cell phone numbers
Add results to your contacts with one click
Mr. Number recognizes tens of thousands of nuisance callers like telemarketers and lets you report spam calls from your phone
It's like Caller ID for your iPhone!

Mr. Number includes 20 free lookups. After this lookups are 99c for 20 (5c each). There's no charge if we can't find a name, the number is in your contacts, you've looked it up before, or we can't find a name.

Compare Mr. Number to every other reverse lookup app in the store! Most charge 99c for a single lookup. One lets you look up landline numbers for free but charge $1.99 for every single cell phone number! Mr. Number costs just 5c per lookup.
