# Delaware

Company data from the Delaware business register, through the Topograph API.

> **Beta**: this country is in early development. Some datapoints or documents may be missing, the integration may be unstable, prices may change without notice, and it is not covered by SLAs.

## Overview

Topograph reads Delaware Division of Corporations and returns the company profile and other key persons of Delaware companies through one API.

## Coverage

What comes back for each datapoint and document, as on the coverage matrix.

Requests run in prefill mode (fast) or verification mode (the authoritative register answer).

| Datapoint | Returned |
| --- | --- |
| Company profile | Yes |
| Other key persons | Yes |

| Document | Returned |
| --- | --- |
| Register extract | Yes |
| Articles of association | No |
| Financials | No |
| UBO extract | No |

### Documents, as the register names them

- Entity Search Status Copy

### Speed

A company profile typically comes back from the register in 2 s in prefill mode. These are typical observations, not a service-level commitment: set your timeouts well above them.

## Sources

The registers this country’s data comes from. Secondary sources only enrich or check what the registers return.

- **[Delaware Division of Corporations](https://icis.corp.delaware.gov/eCorp/)**: The official filing portal of the Delaware Division of Corporations, part of the Delaware Department of State. The Division counted more than 2.2 million business entities at the end of 2025: limited liability companies, corporations, limited partnerships and statutory trusts. Its entity search lists active and inactive entities by name or file number and shows the entity name, file number, entity kind and type, formation date, residency and registered agent. The official entity status is published on the Entity Status Report.
- **[GLEIF (Legal Entity Identifiers)](https://www.gleif.org/en/lei-data/gleif-golden-copy/download-the-golden-copy)** (secondary): Global Legal Entity Identifier Foundation – Legal Entity Identifier reference data
