# Address, Phone, Email and People Match Sources

> Mar 9, 2026

The web presence response now includes `address_match_sources`, `phone_match_sources`, `email_match_sources`, and `people_match_sources` fields.

These arrays tell you exactly which online source (one or multiple) confirmed each piece of contact information. Possible sources include:

`INPUT_WEBSITE` — the website you provided
`FOUND_WEBSITE` — a website discovered during analysis
`SOCIAL_PROFILE` — a social media profile
`REVIEW` — an online review platform
`DIRECTORY_LISTING` — a directory listing (e.g., BBB, Yelp)

This gives you full transparency into where Baselayer found matching data, making it easier to assess confidence in each data point.
