Best company headquarters location API 2026
Nine APIs—People Data Labs, Apollo, Parallel, Predict Leads, Explorium, CompanyEnrich, ZoomInfo, Exa, and Seltz—receive the same company domain and enrich it by API calls from their official docs.
Parallel has the highest measured HQ-location correct-field yield: 90.9%, with 250/275 eligible company headquarters correct.
Their primary headquarters city and country were normalized and judged against human-reviewed Ground Truth. The table separates correct yield, coverage, and accuracy when returned.
Headquarters correctness, completeness, and writeback risk.
Correct-field yield is the primary ranking because it penalizes both missing and incorrect HQ locations. Coverage measures whether a provider returned a location; accuracy when returned measures how often a populated location was correct.

How much does company headquarters location data cost per record, and which API is cheapest?
At each provider's public entry self-serve rate, Nimble lite was the cheapest for the full 282-company run at $0.31, about $0.00 per company record. Pricing is for the whole enrichment call, not this field alone; no provider prices company headquarters location data separately. Cheapest is not best: read cost beside this page's accuracy table.
Which API has the most accurate company headquarters data?
Parallel has the highest measured end-to-end HQ-location yield at 90.9% (250/275 eligible headquarters correct). Compare coverage and accuracy when returned separately if missing values and incorrect CRM writebacks have different costs.
What location does this benchmark measure?
It measures the company's primary headquarters city and country. It does not score street address, postal code, legal domicile, incorporation jurisdiction, branch offices, service areas, or every operating location.
How do I enrich a list of company domains with headquarters locations?
Send the same normalized primary domain to each candidate API, map the result into separate city and country fields, and measure missing and incorrect values separately. Keep HQ enrichment distinct from address verification or office-location discovery, which require different Ground Truth.
