> **In short:** Visitor identification (phone capture) finds the phone numbers of people who visited your site but did not leave a request, and sends them to your CRM. To start, check that the site has this project’s code, turn identification on in the Visitor identification section and, if needed, set a trigger delay and a source filter.

Most visitors look at the site and leave without filling in a form. Visitor identification — it is also called phone capture — helps you win some of them back: the system finds the phone number of such a visitor and sends it to your CRM as a lead. Watch the two-minute video, then use the steps below.

## How phone capture works

When a visitor leaves the site without a request, the system matches their digital fingerprint against a contact base. If there is a match, you get the phone number and can call the person while they are still choosing.

## How to turn it on

1. **Check the code on the site** — Open **Code on the site**, enter the page address and click **Check the code**. Identification works only on pages with the LPTracker code of this very project — the code of another project does not count.
2. **Turn identification on** — The price of each contact found is shown right under the switch. If your account has free identifications, their counter is shown in the Status block.
3. **Set the trigger delay** — The delay filters out people who opened the site for a couple of seconds. Five to fifteen seconds works for most sites.
4. **Set up the source filter if needed** — A whitelist identifies only visitors from the selected sources and campaigns, a blacklist — everyone except them.

> Identifications are paid from the balance, so keep it topped up — see [topping up the balance and auto-payment](http://my.lptracker.ru/land/lk/faq/?a=balance-topup&format=md&lang=en). After you turn identification off, numbers may keep coming for a few more days.

## Only the ads you need

If you only want contacts from certain campaigns, turn on the source filter, choose the whitelist and add rules: a source and, if needed, a campaign. Rules are saved right after each change.

## How to call these leads

This is a cold contact: the person only visited your site and did not leave a request. The manager should start the conversation calmly and ask whether your service is relevant — and be ready for the question “Where did you get my number?”.

> Don’t say “you left a request on our website” — the person didn’t, and the call will end in irritation. Better: “It came to me in the CRM, so I’m calling. Is an apartment renovation relevant for you?”

## Frequently asked questions

### Why are no numbers coming after I turned it on?
Check the status of the code: identification works only where the code of this project is installed. Also make sure the delay is not too long and the source filter does not exclude your traffic.

### How much does it cost?
The price of each identification is shown under the switch in the Status block. Only contacts that were found are charged.

### Can I get numbers only from ads?
Yes: turn on the source filter, choose the whitelist and add the sources and campaigns you need.

### What happens after I turn identification off?
New identifications stop, but numbers that were already being processed may keep coming for a few more days.
