Data Availability

API access: US-DE is not yet part of the public countryCode enum. Contact us to enable it on your workspace. Requests sent with countryCode: "US-DE" will otherwise return 400 until the enum is expanded.

Data Sources

Delaware data is sourced from the Delaware Division of Corporations, ICIS eCorp portal (icis.corp.delaware.gov/eCorp/). The register indexes over 1.8 million entities: corporations, LLCs, limited partnerships, statutory trusts, and other business formations registered in Delaware. It is operated by the Delaware Department of State. Two tiers of data are available:

Free-tier lookup (fast, non-authoritative). Entity name, file number, entity classification, formation date, residency, and registered agent. The official entity status is not available on the free tier.
Entity Status Report (paid, authoritative). The same fields as the free tier, plus the official entity status (Good Standing, Void, Forfeited, and so on), sourced from the paid Delaware Entity Status Report. The report document is also included at no extra charge.

Status requires the paid tier. Delaware does not expose entity status on the free portal. To receive company.status, request the authoritative mode or include the status data block in your /v2/company call. See the pricing page for the current price.

Company Identifiers

Query Identifiers

Identifier Type	Format	Example	Notes
Delaware File Number	Numeric, 4 to 10 digits, no leading zeros	`3177627`	Assigned by the Delaware Division of Corporations at formation. Covers all entity types.

Pass the file number exactly as the register assigns it: no leading zeros, no separators. File number 3177627 is valid; 03177627 is not. Use /v2/search first to resolve a name to the canonical file number before calling /v2/company.

Identifiers in API Response

Identifier	Format	Example	Found In
`fileNumber`	Numeric, 4 to 10 digits	`3177627`	All entities

Search Capabilities

Search Type	Pattern	Example	Match Type	Expected Results
By Name	2-100 chars	`"Acme LLC"`	Starts-with (case-insensitive)	Up to 50 results
By Delaware File Number	Numeric	`3177627`	Exact (`matchType: id`)	Single result

Starts-with search. Name search anchors on the beginning of the legal name (case-insensitive). Use a more specific query to narrow a large result set. Results are capped at 50 per request.

Foreign qualifications are excluded from default results. ICIS indexes both domestic entities (formed in Delaware) and foreign qualifications (entities formed elsewhere that are registered to do business in Delaware). Foreign qualifications are filtered out by default. The authoritative record for those entities lives in their state of formation.

Quirks & Gotchas

Quirk	Details
Status requires the paid tier	The official entity status (Good Standing, Void, Forfeited, and so on) is only available through the paid Entity Status Report. Free-tier lookups return `company.status = undefined`.
No officers or directors on any tier	Delaware law does not require officers or directors to be disclosed on the public portal. Officer names appear only inside paid annual-report document images and are not available through this API.
LLC members are never disclosed	Delaware LLC membership is not filed with the state at formation and does not appear on annual reports. This is a statutory privacy feature under Delaware law, not a paywall.
No shareholders or UBOs	Ownership and beneficial-ownership information is not part of the Delaware public record for any entity type.
No legal address on the free tier	The free ICIS tier only exposes the registered agent’s address, not the entity’s legal address. `company.legalAddress` is not populated on the free tier.
No activity codes	NAICS, SIC, and NACE codes are not collected by the Delaware business register.
Sole proprietors are not indexed	Sole proprietors register with state tax and county offices, not with the Delaware Division of Corporations.
Entity Status Report deduplication	The paid Entity Status Report purchase is cached for 24 hours per entity. If you call both `company` and document retrieval within that window, the report is fetched once and billed once.
”Do not quote the query” rule	Do not wrap name search queries in quotation marks. The register returns an error for quoted inputs.

Mappings

Legal Forms

Delaware classifies entities with two labels: an Entity Kind (the primary classification) and, for corporations, an Entity Type (a sub-classifier). Topograph maps these to a standardized form and to an ISO 20275 ELF code where one exists.

All Delaware entity classifications

Local Name	Entity Kind	Entity Type	Standardized	ISO 20275
Corporation	Corporation	General	Corporation	`8888`
Close Corporation	Corporation	Close	Corporation
Public Benefit Corporation	Corporation	Public Benefit	Corporation
Non-Stock Corporation	Corporation	Non-Stock	NonprofitOrganization
Professional Corporation	Corporation	Professional	Corporation	`9AAS`
Exempt Corporation	Corporation	Exempt	NonprofitOrganization
Limited Liability Company	LLC		LimitedLiabilityCompany	`WYG5`
Limited Partnership	LP		Partnership	`FE1L`
Limited Liability Partnership	LLP		Partnership
General Partnership	GP		Partnership
Statutory Trust	Statutory Trust		Trust
Trust	Trust		Trust

The full legal form table with ISO 20275 mappings is available on the Delaware pricing page.
