MAC address vendor

Aevoe Inc. (Moshi) — 00:14:3D (MA-L)

Primary prefix
00:14:3D
Block
MA-L
Status
Active

Summary

// what this is
Aevoe is registered to MAC prefix 00:14:3D in the IEEE OUI database. When a device's MAC address begins with 00:14:3D, that block was registered by Aevoe — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A MAC starting 00:14:3D most likely identifies Moshi Bluetooth audio hardware filed by Aevoe Inc. under FCC grantee 2AA7Y, rather than the brand's passive cases or chargers; no evidence supports Wi-Fi or IoT device attribution for this block.

About this vendor.

Updated  ·  Confidence: Likely  ·  7 sources  ·  How this page is checked

A MAC address starting with 00:14:3D belongs to Aevoe Inc., a Taipei, Taiwan-based company operating under the Moshi consumer-electronics brand, and is most plausibly seen on Moshi Bluetooth audio hardware — on-ear headphones and earbuds — rather than the brand's passive accessories.

Aevoe Inc. holds a single MA-L (24-bit OUI) block, 00:14:3D, registered to an address on Keelung Road in Taipei's Xinyi District. No second OUI assignment for Aevoe appears in the IEEE MA-L, MA-M (the IEEE MA-M registry), or MA-S (the IEEE MA-S registry) registries, so this is a one-company, one-block registration rather than a multi-OUI footprint.

Company substance for this registrant comes from its own regulatory filings rather than a trademark record: FCC grantee code 2AA7Y is registered directly to Aevoe Inc. at a Taipei address, and covers 21 FCC equipment authorizations for Moshi-branded RF products, including a Bluetooth-earphone filing and several Qi wireless-charging SKUs. This ties the actual OUI registrant to a live hardware line with no entity mismatch.

Device attribution should stay broad rather than pinned to one discontinued model. Independent press (The Gadgeteer, 9to5Google) reviewed the earlier "Avanti Air" Bluetooth on-ear headphones, and Moshi's current catalog lists newer Bluetooth on-ear and earbud models. No Wi-Fi, smart-home, or other IP-networked Moshi hardware was found, so attribution for this prefix should stay narrow to Bluetooth audio accessories.

A separate US trademark for "MOSHI" (serial 86771973, filed 2015-09-29, registered 2018-01-16) is held by "Aevoe Corp.," San Francisco, CA — a distinctly named, distinctly located entity from OUI registrant Aevoe Inc. of Taipei. No source found ties the two companies together, so the trademark is not used as substance for this entry.

No CVE, malware association, or security advisory referencing "Aevoe," "Moshi," or the 00:14:3D prefix was found as of an August 2026 search, including a check against current Airoha Bluetooth-chip CVEs (2025-20700, 2025-20701, 2025-20702), whose published affected-brand lists do not name Moshi.

Corporate-entity caution
a US trademark "MOSHI" (serial 86771973, granted 2018) is owned by "Aevoe Corp.," San Francisco, CA — not "Aevoe Inc.," Taipei, the OUI registrant; no source ties the two companies together, so this record is not used as substance here [Unknown] — https://tsdr.uspto.gov/statusview/sn86771973

Regulatory footprint
FCC grantee code 2AA7Y registered directly to Aevoe Inc. (Taipei), 21 RF product authorizations including a Bluetooth-earphone filing and several Qi wireless-charging SKUs [Likely] — https://fccid.io/2AA7Y/amp
Corporate-entity caution
a US trademark "MOSHI" (serial 86771973, filed 2015-09-29, registered 2018-01-16) is owned by "Aevoe Corp.," San Francisco, CA — not "Aevoe Inc.," Taipei, the OUI registrant. No source found establishes these are the same or a related company, so the trademark is not used as substance for this entry
[Unknown] — https://tsdr.uspto.gov/statusview/sn86771973
Third-party date artifact
a third-party aggregator lists a registration date for 00:14:3D; IEEE's own OUI data publishes no assignment date, so that figure is a database artifact and is not carried into this entry as an IEEE fact [Confirmed] — https://maclookup.app/vendors/aevoe-inc
Security context
no CVE, malware, or advisory reference to Aevoe, Moshi, or 00:14:3D found as of an August 2026 search, including cross-check against current Airoha Bluetooth-chip CVEs (2025-20700, 2025-20701, 2025-20702), whose published affected-brand lists do not name Moshi
[Likely] — general web/CVE search, no single citable URL

none confirmed [Unknown]
Analyst note
this is a single-OUI registrant, but it is backed by an identifiable, actively trading company that files its own FCC equipment authorizations (grantee 2AA7Y) for Bluetooth and wireless-charging hardware under the Moshi brand — treat the block as belonging to genuine Moshi Bluetooth-audio hardware, not Wi-Fi or IoT devices, since none were found under this OUI.
