# Voter Matched Sample (L2)

> Target L2-verified respondents, pass voter IDs in real time, and append voter-file data post-field.

Research Desk is the first DIY sampling platform to offer **voter-matched respondents** via L2. Use it for political and public-opinion research when you need higher-confidence identity verification and voter-file attributes.

<Tip>
  L2 Voter Matching sources verified respondents from L2's voter database, with registration status and modeled demographics available for targeting, segmentation, and weighting.

## Target L2-verified respondents

<Steps>
  <Step title="Open Qualifications">
    In your Internal source (Buy Sample), open the Qualifications panel.
  </Step>

  <Step title="Search for L2 Voter Verified">
    Find **L2 Voter Verified** under the Verified Sample category.
  </Step>

  <Step title="Select Yes">
    Choose **Yes** to allow only L2-verified respondents through this source.
  </Step>

  <Step title="Launch">
    All incoming respondents are pre-matched against L2's database. You receive each respondent's L2 ID (LALVOTERID).
  </Step>
</Steps>

With this qualification applied, every entrant is an L2 Verified Respondent whose identity was matched before they reach your survey.

## Pass L2 data in real time

Add placeholders to your survey entry link alongside `[%RDUD%]`:

| Placeholder       | Returns                  | Example use                                  |
| ----------------- | ------------------------ | -------------------------------------------- |
| `[%L2_Verified%]` | `1` = yes, `2` = no      | Capture verification status in embedded data |
| `[%L2_ID%]`       | L2 voter ID (LALVOTERID) | Store for post-field matching                |

Example entry link:

```
https://www.yoursurvey.com/start?rdud=[%RDUD%]&L2status=[%L2_Verified%]&LALID=[%L2_ID%]
```

Map each placeholder to a field in your survey platform (embedded data, custom variable, etc.).

## Request additional L2 data points

Beyond the L2 ID, you can request specific voter-file fields from L2's data dictionary:

1. Launch your source
2. Reply to the launch notification email listing the data points you need
3. For post-field append (non-real-time fields), contact the Rep Data support team after fieldwork — they deliver requested fields via CSV

Real-time append of full voter-file attributes beyond L2 ID is not available today.

## Pricing

| Component                  | Cost                                                   |

| **Data append** (optional) | +\$2.50 CPI additional                                 |
