- Which business identifiers reduce duplicates?
- What should never be inferred?
Nigeria manufacturing research worksheet
Build a company list from registry, industry, and official company evidence. Record business contact routes separately from personal contact details.
| Column | What to record | Validation rule |
|---|---|---|
| company_name | Registered or trading name | Preserve the source spelling |
| registration_reference | Registry identifier, when public | Do not invent or normalize away identifiers |
| manufacturing_evidence | Published product, facility, or industry evidence | Link the exact supporting source |
| location | City/state or facility location | Separate registered office from plant location |
| business_url | Official company website | Confirm the domain represents the same entity |
| source_url | Evidence URL | Required for every row |
| checked_at | Date reviewed | Use ISO format: YYYY-MM-DD |
Research safeguards
- Do not infer manufacturing activity from a company name alone.
- Do not publish guessed email addresses as company contacts.
- Keep registry facts, website observations, and analyst conclusions in separate fields.
- Respect correction, deletion, and opt-out requests.
A defensible workflow
- Start with a primary or official source and record the URL and access date.
- Separate observed facts from assumptions. Never infer a personal email address or verification score.
- Deduplicate by legal name, domain, and location; keep evidence for every important claim.
- Before outreach, confirm applicable privacy, marketing, and opt-out requirements.
Evidence record
| Field | What to record | Why it matters |
|---|---|---|
| Entity | Organization name and website | Prevents person, branch, and brand mix-ups |
| Observation | Specific fact found in the source | Keeps research auditable |
| Source | URL, publisher, and access date | Allows independent checking |
| Confidence | High, medium, or unresolved | Stops assumptions becoming facts |
| Action | Review, correct, remove, or do not contact | Creates a responsible next step |
