# Recognizing and merging contacts

> One contact per person across every chat widget and mailbox: conversation history, recognition, the visitor profile, merging and deleting.

A contact is a person you talk to. This page explains how the same person becomes one contact, how visitors are recognized and how contacts are merged or deleted. Stages, lists and reminders: [Contacts and lists](https://hrc.lt/en/docs/contacts/contacts-and-lists).

## One contact everywhere

The same person writing through several chat widgets and by e-mail is one contact. They are joined by a verified e-mail or by your site's user id ([Identity verification](https://hrc.lt/en/docs/widget/identity-verification)).

## Anonymous visitors

Until a visitor gives an e-mail or is recognized, they show as "Visitor" with a short number. Once recognized, the anonymous contact is merged into the recognized one.

## Profile and activity

The contact page shows the company, phone, tags, custom fields with their source and all recorded activity. How to send them from your site: [Visitor profile](https://hrc.lt/en/docs/widget/visitor-profile).

## Merging and deleting

You can merge two contacts of the same person by hand. Deleting a contact deletes its conversations, profile and activity. Before deleting, the app shows what will be lost.
