Address-to-Identity Correlation

4 min read Apr 11, 2026

Overview

Address-to-identity correlation starts from a known address and finds all individuals and entities associated with it. This is the reverse of name-based lookup and is one of the most productive techniques in relationship mapping. A single address often yields multiple subjects: family members, business partners, tenants, and associated companies. Each new identity found at the address becomes a new investigation seed.

Companies registered at a residential address are a strong indicator of a connection between the address and the company's directors or shareholders. Both the UK and US company registries support address-based search.

Search Companies House by registered address:

┌──(kali㉿kali)-[~]
└─$ curl -s "https://api.company-information.service.gov.uk/search/companies?q=$ADDRESS" -u $COMPANIES_HOUSE_API_KEY: | jq '.items[] | {name: .title, number: .company_number, status: .company_status, type: .company_type}' 
{
  "name": "SMITH CONSULTING LTD",
  "number": "12345678",
  "status": "active",
  "type": "ltd"
}

Each company returned at the address leads to its directors and persons with significant control, expanding the set of associated individuals. A residential address with multiple companies registered to it may indicate a registered office service provider rather than a genuine operational address, but the companies' officers are still worth investigating.

Electoral Roll Reverse Lookup

Commercial people search platforms that incorporate electoral roll data support address-based search, returning all individuals registered to vote at that address. This is the most direct method for identifying all residents at a property.

UK-focused sources that support address lookup:

  • 192.com returns electoral roll entries by address with subscription access

  • FindMyPast and Ancestry hold historical electoral data going back decades, useful for establishing long-term residency

  • Credit reference agency data accessed through legitimate commercial channels returns current and historical residents

Planning applications submitted for a property name the applicant and agent. Searching by address rather than by name returns all applications submitted for that property, revealing historical owners or occupants who carried out works:

┌──(kali㉿kali)-[~]
└─$ curl -s "https://api.planningportal.co.uk/search?address=$ADDRESS&format=json" -H "Authorization: $PLANNING_API_KEY" | jq '.results[] | {applicant: .applicant_name, description: .development_description, date: .decision_date}'

Court filings that include an address as a defendant or claimant location can be searched in reverse. County court judgment searches by postcode or address return all judgments recorded at that address, potentially naming multiple individuals or companies that have been subject to proceedings there.

Search Engine Address Queries

Addresses appear across a wide range of publicly indexed sources: business listings, social media profiles, news articles, forum posts, and document metadata. A direct quoted address search surfaces all of these:

"123 High Street, London, EC1A 1BB"
"EC1A 1BB" "123 High Street"
"123 High Street" "EC1A" site:linkedin.com
"123 High Street London" contact

Format the address multiple ways since the same address appears differently across sources. Include and exclude postcode, abbreviate or spell out street type, and try both comma-separated and space-separated formats.

Satellite and Street-Level Imagery

Once an address is confirmed, satellite and street-level imagery provides physical context: the type of property, visible vehicles, business signage, and any identifiable features that support or contradict other intelligence. Cross-reference what is visible at the address against claims made in documents or profiles.

For detailed geolocation and imagery analysis techniques, see the Geolocation and Imagery Intelligence phase.

Neighbour and Surrounding Address Research

When a subject uses a registered office or accommodation address rather than their actual residence, researching nearby addresses in company filings and electoral data can identify the true centre of activity. Clusters of companies or individuals in adjacent properties sharing directorship or ownership patterns indicate a connection worth investigating.
