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.

Search Capabilities

Search TypePatternExampleMatch TypeExpected Results
By Name2-100 chars"Acme LLC"Starts-with (case-insensitive)Up to 50 results
By Delaware File NumberNumeric3177627Exact (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

QuirkDetails
Status requires the paid tierThe 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 tierDelaware 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 disclosedDelaware 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 UBOsOwnership and beneficial-ownership information is not part of the Delaware public record for any entity type.
No legal address on the free tierThe 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 codesNAICS, SIC, and NACE codes are not collected by the Delaware business register.
Sole proprietors are not indexedSole proprietors register with state tax and county offices, not with the Delaware Division of Corporations.
Entity Status Report deduplicationThe 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” ruleDo not wrap name search queries in quotation marks. The register returns an error for quoted inputs.

Mappings

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.
