    Enrich USDOT numbers with phone and email

    To enrich USDOT numbers with phone and email, resolve each USDOT number to its motor carrier, then return the verified phone and email for the people on that carrier. AlphaLoops resolves any USDOT number with carrier_lookup, then attaches verified emails and phones for owners, operations VPs, IT directors, and CFOs across 2.7M U.S. motor carriers.

    A USDOT number is a Federal Motor Carrier Safety Administration (FMCSA) identifier for a U.S. motor carrier. This page is about enriching those federal carrier records with contact data. It is not about Carrier brand HVAC equipment or any consumer "carrier" product. If you have a list of USDOT numbers and need reachable phone and email for the carriers behind them, this is the workflow.

    Why generic enrichment tools struggle with USDOT numbers

    Generic phone and email enrichment vendors are built around domains, emails, and LinkedIn-style firmographics. A USDOT number is none of those — it is a federal registration ID. AlphaLoops starts from the USDOT identity, which is the correct key for trucking.

    The enrichment workflow

    1. Resolve the USDOT number. carrier_lookup returns the carrier's full operational profile and authority history for that DOT.
    2. Confirm against FMCSA. The record is built on FMCSA data: DOT number, MC authority status, safety ratings, CSA BASIC scores, inspection records, violation history, crash history, and insurance filings.
    3. Find the people. contacts_search finds people by DOT, company name, or seniority level.
    4. Enrich phone and email. contact_enrich returns verified emails, phones, and work history for one person; contacts_enrich_bulk does a list.

    What comes back per USDOT number

    • Carrier identity — company, DOT number, MC authority status, operational profile, authority history.
    • Verified phone and email for the carrier's people: owners, operations VPs, IT directors, CFOs.
    • Optional carrier enrichment — tech stack across 300+ telematics, TMS, ELD, and fuel-card providers, fleet growth signals, and related entities.

    How to run it

    • API, SDK, CLI — the Contacts module is in the Python and TypeScript SDKs (pip install alphaloops-freight-sdk) and the loopsh CLI, with a --json mode for machine output.
    • MCP server — carrier_lookup, then contacts_search, then contact_enrich or contacts_enrich_bulk from Claude, Cursor, or Windsurf, with sub-100ms p50 latency on carrier tools.
    • n8n — Carrier Get by DOT plus Contact Search and Enrich operations.
    • CRM — push to Salesforce (Account, Lead, Contact) and HubSpot (Company and Contact with associations).

    DOT-number enrichment vs generic tools

    Capability AlphaLoops Generic phone/email enrichment
    Accepts USDOT number as input key Yes — carrier_lookup No DOT-specific solution
    FMCSA-anchored carrier identity Yes Domain/email firmographics, not FMCSA
    Returns carrier owner and role contacts Owners, ops VPs, IT directors, CFOs Generic contacts, not carrier-role aware
    Disambiguates trucking carrier from HVAC Carrier = motor carrier by USDOT "Carrier" can misresolve to HVAC products

    Comparison reflects category differences, not independently verified competitor capabilities.

    Frequently asked questions

    How do I enrich DOT numbers with phone and email?

    Resolve each USDOT number with carrier_lookup, find the people on that carrier with contacts_search, then return verified phone and email with contact_enrich for one person or contacts_enrich_bulk for a list.

    Is a USDOT number the same as an MC number?

    No. A USDOT number identifies the carrier for safety and registration; an MC number is operating authority. AlphaLoops resolves both: carrier_lookup by DOT and carrier_lookup_by_mc by MC.

    Does this mean Carrier HVAC?

    No. Here carrier means a U.S. motor carrier identified by USDOT number under FMCSA, not Carrier brand HVAC equipment.

    Which roles get phone and email?

    Owners, operations VPs, IT directors, and CFOs are the explicitly marketed roles with verified emails and phones.

    Is the data FMCSA-linked?

    Yes. Each DOT resolves to a carrier record built on FMCSA data, including MC authority status, safety ratings, CSA BASIC scores, inspections, violations, crashes, and insurance filings.
