Jabil Circuit (Shanghai) Ltd. — 2 prefixes (MA-L)

A MAC address starting with 14:63:08 or 4C:0D:EE belongs to Jabil Circuit (Shanghai) Ltd., an electronics manufacturing services (EMS) subsidiary of Jabil Inc., and typically identifies a contract-assembled device rather than a product Jabil ships under its own brand.

Both prefixes are dedicated IEEE MA-L (/24) blocks registered solely to this entity, at the identical registered address FL5-Unit A2, No. 1528 Gumei Road, Shanghai, CN 200233. Neither is a slice of a shared IEEE pool (unlike 70:B3:D5), so either prefix alone is an unambiguous signal for this registrant.

The entity has verifiable substance beyond the bare registration: jabil.com lists "Jabil Circuit (Shanghai) Limited" as a subsidiary, and FDA/BEUDAMED registration records plus FDA MAUDE adverse-event report titles name "JABIL CIRCUIT (SHANGHAI) LTD" as manufacturer of record for the Boston Scientific LATITUDE Communicator, an implantable-cardiac-device remote-monitoring accessory.

Because this is an EMS assembler, the OUI identifies who built the hardware, not the brand printed on it — the LATITUDE Communicator case is the only documented device tie found. A separate parent record, plain "Jabil" of St. Petersburg, FL, holds an unrelated MA-S sub-allocation inside the shared pool 70:B3:D5 and must not be conflated with this Shanghai entity.

IEEE assignment

14:63:08, 4C:0D:EE → JABIL CIRCUIT (SHANGHAI) LTD., registered Shanghai, CN [Confirmed] — the IEEE MA-L registry 146308, the IEEE MA-L registry 4C0DEE

Registry / block size

MA-L (24-bit OUI); two dedicated blocks, neither part of a shared IEEE pool [Confirmed] — the IEEE MA-L registry 146308, the IEEE MA-L registry 4C0DEE

HQ / registered address

FL5-Unit A2, No. 1528 Gumei Road, Shanghai, CN 200233 [Confirmed] — the IEEE MA-L registry 146308

Device types

contract-assembled electronics; documented medical-device remote-monitoring accessory (Boston Scientific LATITUDE Communicator) [Likely] — FDA MAUDE search-result titles (direct detail-page fetch returned HTTP 404, likely bot-blocked, so this rests on titles/metadata not a fetched page body)

Notable products

Boston Scientific LATITUDE Communicator / External Communicator, as assembler of record [Likely] — FDA MAUDE search titles; https://beudamed.com/fda_registrations/525bd790-e4fa-463f-98e7-d25085583c4f

Registration dates

IEEE's public OUI data publishes no assignment/registration date for MA-L blocks; maclookup.app (third-party) shows 2011-08-05 for 14:63:08 and 2013-11-12 for 4C:0D:EE as a database artifact, not an IEEE fact [Confirmed that IEEE publishes none; third-party dates unverifiable against a primary source] — https://maclookup.app/vendors/jabil-circuit-shanghai-ltd

Security context

no malware, botnet, or CVE association found for either prefix or for the company name, as of an August 2026 web search [Unknown — sourced negative, not an exhaustive clearance] — general web search, no dedicated abuse-feed check performed

Related vendors

parent "Jabil" (St. Petersburg, FL) holds a separate MA-S sub-allocation inside the shared IEEE pool 70:B3:D5, a distinct registrant record from this Shanghai entity [Confirmed] — /mac/vendor/jabil/; other same-family regional entities (Jabil Circuit Guangzhou, Jabil Circuit Hungary, Jabil Circuit de Chihuahua) named in company materials but cross-linking not verified this pass [Likely]

Analyst note

A match on 14:63:08 or 4C:0D:EE reliably identifies hardware assembled by Jabil Circuit (Shanghai) for an undetermined third-party brand; classify the actual product via hostname, DHCP fingerprint, or other signals, not from the OUI alone [Likely] — synthesis of registry and FDA MAUDE findings
