AI summary
To get an MC number, first determine the required operating authority, then use FMCSA's current registration workflow and submit the applicable filing. FMCSA's Get an MC Number page, accessed 2026-07-21, is the named source and distinguishes 3 docket prefixes. A number assignment alone does not activate authority.
Each receipt below describes its exact retained artifact or live source. Dates and digests never cross artifact boundaries.

Scope and material limitation
This guide gives the official handoff and decision sequence. Current forms, fees, and timing must be read on FMCSA before filing.
Dated source facts
Source-snapshot manifest receipt
This receipt attests the source snapshot manifest, not any individual fact.
The answer-series chain record is unsigned. It does not authenticate a person, organization, eligibility state, or individual fact.

Limitation: Registration workflow, forms, fees, and timing can change. Assignment of a docket number alone does not establish active operating authority.

Frequently asked questions
What’s on file, by the numbers
Platform snapshot · 2026-07-28
Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.
Source authority is record-specific
Use the issuer named on the record.
Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.
Reproducible by design
Inspect the evidence each published figure actually supplies.
Source and date
Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.
Available derivation
Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.
Daily observations
Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
