GOFO Express Tracking API & MCP

Query live GOFO Express (gofo) US last-mile package status and scan history in a single synchronous GET request or MCP tool call. lastscanned auto-detects 18-character GFUS… barcodes in Pass 1 and 15-character GF… barcodes in Pass 2, returning a normalized TrackingResult JSON payload—with zero carrier credentials or webhook registration required.

Overview & Quick FactsCopy Anchor Link

Why developers use lastscanned for GOFO ExpressCopy Anchor Link

• No shipper contract or webhook setup: GOFO's merchant API is only provisioned to direct high-volume shippers and consolidators. lastscanned lets any e-commerce store, 3PL, or AI support agent query GOFO shipments synchronously via GET /v1/track/:number.
• Fixes GOFO's hardcoded -0700 timezone offset bug: GOFO's upstream API prints each scan in the facility's local clock alongside an IANA processTimeZone (e.g. America/New_York), but hardcodes -0700 on the timestamp string regardless of state. lastscanned strips the bogus offset and converts the scan's local clock using its true IANA timezone so timestamp (UTC) and localTime are always accurate.
• Strips boilerplate support footers: GOFO appends "For Delivery Issues & Tracking Support..." to every delivered scan description; lastscanned strips this noise automatically.

Tracking Number Formats & Auto-Detection (matches vs mayMatch)Copy Anchor Link

GOFO is evaluated eighth (#8) in lastscanned's two-pass detector and supports both Pass 1 (matches) and Pass 2 (mayMatch):

Disambiguating GOFO vs Cirro & YunExpress (?carrier=gofo)Copy Anchor Link

• Auto-detected (GFUS + 14 digits and GF + 13 digits): No ?carrier= parameter is needed.
• Querying GOFO by shipper number (CR… or YT…): GOFO's tracking system also indexes parcels by their upstream Cirro (CR + 12 digits) or YunExpress (YT + 16 digits) waybill numbers. Without ?carrier=gofo, CR… routes to cirro and YT… routes to yunexpress. Pass ?carrier=gofo if you want to query GOFO directly using the upstream shipper number.

Raw status & process codes: events[].code preserves GOFO's processCode ("100" → label_created, "200" loaded on vehicle, "201"/"202" arrived at station/hub, "205" → delivered, "208" → out_for_delivery, "411"/"412" → in_transit), while package-level statuses (Processing, Transit, Delivered, Alert, Returned) map cleanly to the 7 standard statuses.

Carrier-Specific Status & Integration NotesCopy Anchor Link

• CIRRO E-Commerce acquisition: GOFO acquired Cirro E-Commerce in 2026 and handles US last-mile delivery for Cirro parcels. You can track GFUS… numbers under gofo (default) or cirro.
• High-throughput batch support: Up to 35 GOFO tracking numbers can be queried in a single batch call via GET /v1/track?numbers=....
