# Lead Data

> Look up and import contacts from external data sources.

**Lead Data** is where contacts come into the platform from outside it. Its four sub-pages cover three ways to find people and one place to see what they cost.

## In This Section

* **[Enrichment](/find-enrich/lead-data/enrichment)** — Look up one contact or company by any identifier you have and get back verified details.
* **[People Search](/find-enrich/lead-data/people-search)** — Build an audience from filters — industry, seniority, location, company size, and more.
* **[Sales Navigator](/find-enrich/lead-data/sales-navigator)** — Turn a LinkedIn Sales Navigator search into a list of leads.
* **[Credits](/find-enrich/lead-data/lead-credits)** — Your data credit balance and what each lookup costs.

## Which One Should I Use?

| You have                                            | Use                                                                           |
| --------------------------------------------------- | ----------------------------------------------------------------------------- |
| A person's email, phone, or LinkedIn URL            | [Enrichment](/find-enrich/lead-data/enrichment)                               |
| A company name or domain, and you want people there | [Enrichment](/find-enrich/lead-data/enrichment) — it previews matching people |
| A description of your ideal customer, but no names  | [People Search](/find-enrich/lead-data/people-search)                         |
| A Sales Navigator search you've already built       | [Sales Navigator](/find-enrich/lead-data/sales-navigator)                     |

All three save their results into a [Smart List](/find-enrich/smart-lists), so the next step is the same no matter which you use.

## About Data Credits

Enrichment, People Search, and Sales Navigator all draw on one shared pool of **data credits**. Credits never expire. See [Credits](/find-enrich/lead-data/lead-credits) for balances, costs, and how to top up.

If your plan includes lead data, there is nothing to buy and the Credits page won't appear in your menu.
