# What is 1+1 and 2+2 verification?

1+1, or sometimes written as 1x1, means performing the search on a **single** data source and getting a positive verification response.  
2+2 (or 2x2) indicates that the search was performed using **two or more** different data sources and all of those returned positive verification results. Meaning, the identity was verified on all the data sources. 2+2 is also called **Composite Search**.

Let's take two examples to further understand it. The code snippets below are the results of two separate API calls.

**1+1 Example: **Here only a single data source was used which was *Australia Driver Licence *and the identity was verified.

**2+2 Example*****: ***Here two data sources were used, *Australia Driver Licence* and *Australia Passport*and on both of these the identity was verified.
