Crowley Container Tracking

Track on csight.crowley.com →

A company founded on a rowboat service in 1892 San Francisco harbor now anchors the supply chain of an island of three million — Puerto Rico gets a large share of its consumer goods on Crowley strings out of Jacksonville, where the company is headquartered today.

Regional focus keeps the tracking simple: one prefix, one portal, short voyages. Confirm the CMCU digit math below and cSight does the rest.

4 letters + 7 digits, printed on the doors

CMCU: prefix and SCAC in one

Crowley registers CMCU as its owner code, and the same four letters serve as the liner SCAC on US filings — a convenient overlap shared by few carriers (KMTC being another). Trailers and other equipment in Crowley’s ConRo system carry separate marks, but containerized cargo means CMCU.

Crowley bills of lading

B/L serials also open with CMCU, so document and box share a prefix and the cSight search treats them as one lookup. On ConRo services a single bill often covers mixed freight — a container plus a vehicle, say — and the document-level search is the view that keeps them together.

Using the cSight portal

csight.crowley.com is a Salesforce-based customer portal whose public shipment-tracking page needs no login for basic status. Deep links are not supported, and Crowley publishes no tracking app for phones — the portal is responsive enough to serve that role. Ignore App Store results: the similarly named app is another company entirely.

Fleet rank (Alphaliner, 2026)
outside the top 30

Thomas Crowley’s 1892 Whitehall-boat business grew into a family-held group spanning liner shipping, logistics, government services and energy — still independent, still outside the Alphaliner top 30, and running LNG-powered ConRos years before most of the industry ordered its first.

Frequently asked questions

Is the “Crowley Marine” app the carrier’s tracking app?

No — that app belongs to an unrelated boat-parts and outboard-motor retailer that happens to share the name. Crowley the shipping line offers no dedicated tracking app; use csight.crowley.com in any browser.

What are El Coquí and Taíno?

Crowley’s LNG-powered ConRo ships — combination container and roll-on/roll-off vessels — purpose-built for the Jacksonville–San Juan lane. If you ship containers or vehicles to Puerto Rico with Crowley, odds are they ride one of these two.

Where does Crowley actually sail?

Puerto Rico and the Caribbean, plus Central America — Guatemala, Honduras, El Salvador, Costa Rica and neighbors — out of US Gulf and Southeast ports. No transpacific or Asia–Europe loops; for those trades your cargo moves with a different line.

Why is there no TEU ranking listed for Crowley?

Its container fleet sits outside the Alphaliner top 30, where precise public capacity figures stop being meaningful — a reflection of a regional ConRo network, not of company size, since the wider Crowley group is substantial.

Does the Jones Act apply to Crowley’s Puerto Rico service?

Yes — San Juan is a domestic US trade, so it runs on US-built, US-flagged, US-crewed vessels. Central America and Caribbean international routes carry no such restriction.

Can csight.crowley.com track a shipment without an account?

Basic milestone tracking by container or B/L number is public. An account unlocks documents, invoices and notifications — worth it for regular shippers, unnecessary for a one-off status check.
