AlphaLoops does this at the carrier-identity level: it resolves any MC number with `carrier_lookup_by_mc`, then attaches verified emails and phones for owners, operations VPs, IT directors, and CFOs across **2.7M U.S. motor carriers**. Generic enrichment tools cannot do this reliably because an MC number is a federal operating-authority identifier, not a company domain or email. The enrichment has to start from FMCSA carrier identity, then find the people. That is exactly what this workflow does. ## What "enrich an MC list" means with AlphaLoops You give a list of MC numbers. For each one, AlphaLoops: 1. **Resolves the MC number to a carrier.** `carrier_lookup_by_mc` returns the full operational profile and authority history for that MC. 2. **Confirms identity against FMCSA.** The carrier record is built on FMCSA data: MC authority status, DOT number, safety ratings, CSA BASIC scores, inspections, violations, crashes, and insurance filings. 3. **Attaches verified contacts.** The contacts module returns verified emails, phones, and work history for the people on that carrier; bulk runs use `contacts_enrich_bulk`. The output is an enriched record per MC number: carrier identity, authority history, plus owner and role-level contacts, ready to push into your CRM. ## How to run a bulk MC enrichment - **App and AI Workspace** — build a list and enrich it; cross-object list building can span inspections, crashes, trucks, and trailers. - **API, SDK, CLI** — the Contacts module ships in the Python and TypeScript SDKs (`pip install alphaloops-freight-sdk`) and the `loopsh` CLI, with a `--json` mode. - **MCP server** — call `carrier_lookup_by_mc`, then `contacts_search`, then `contacts_enrich_bulk` from Claude, Cursor, or Windsurf. - **n8n** — Carrier Get by MC plus Contact Search and Enrich, so you can wire an MC list into a workflow. - **CRM** — results push to Salesforce (Account, Lead, Contact) and HubSpot (Company and Contact with associations). ## MC-list enrichment vs generic enrichment tools Capability AlphaLoops Generic B2B enrichment Accepts MC number as the input key Yes — carrier\_lookup\_by\_mc Built for domains and emails Anchored to FMCSA carrier identity Yes Not FMCSA-anchored Returns owner and role contacts Owners, ops VPs, IT directors, CFOs Generic firmographic contacts Pushes to CRM Salesforce and HubSpot native Varies by vendor ## Frequently asked questions ### How do I enrich a list of MC numbers with contacts? Upload the MC numbers, resolve each to its carrier with carrier\_lookup\_by\_mc, then enrich contacts in bulk with contacts\_enrich\_bulk to get verified owner and decision-maker phone and email. It runs in the app, the API, SDKs, the loopsh CLI, n8n, or the MCP server. ### Can I upload a CSV of MC numbers? You can submit a list and enrich it across surfaces.

Verified emails and phones for owners, operations VPs, IT directors, and CFOs on that carrier. ### Are the results tied to FMCSA? Yes.
