Brivo Compatible Access Cards: Prox Cards for Brivo ACS
Brivo ACS panels accept standard 26-bit Wiegand proximity cards alongside Brivo’s own encrypted credentials, which means property managers and facility teams can order compatible replacement prox cards without buying from Brivo’s distribution channel. American Key Cards supplies standard 26-bit proximity cards and key fobs compatible with Brivo ACS reader infrastructure, programmed to your facility code and card number range. One important distinction: Brivo’s proprietary Unified Credential is an encrypted smart card that cannot be reproduced by any third party, and we say so plainly below.
What the Brivo Credential Ecosystem Actually Looks Like
Brivo is one of the most widely deployed cloud-based access control platforms in North America, used across multi-tenant residential buildings, commercial offices, and light industrial properties. What makes Brivo’s credential picture unusual is that it runs a genuine dual-format system. Full technical details for this format are on our Brivo Access Credentials format page.
On one side sit Brivo’s own Unified Credentials. The OEM part numbers B-BUC3-56-SC50, B-BUC3-56-SCP50, and B-BUC3-56-F50 all refer to DESFire EV3 smart cards operating at 13.56 MHz using a 56-bit credential structure encoded with Brivo’s LEAF file format. These are issued and managed entirely through Brivo’s platform and its authorized integrator network. No aftermarket supplier can produce them.
On the other side sits a wide range of standard 125 kHz proximity credentials. Brivo panels accept 26-bit Wiegand H10301 format cards from HID, Schlage, AWID, and compatible sources over the same reader hardware. This is the format that American Key Cards supplies for Brivo installations.
Understanding the Two-Track Credential System
The reason Brivo supports both tracks is practical: most of their commercial and residential customers migrated from legacy proximity systems. Ripping out and replacing every reader in a building on day one is expensive, so Brivo designed their hardware to accept the standard Wiegand formats already in use while offering the upgrade path to encrypted smart credentials when the customer is ready.
Many Brivo-managed properties today still run entirely on standard 26-bit prox. Some have mixed deployments. A smaller number have completed the migration to Unified Credentials. Where you are in that progression determines what kind of card you need.
If your Brivo system is issuing and accepting standard proximity cards, any compatible 26-bit prox card from American Key Cards will work. If your building has already moved to Brivo Unified Credentials exclusively, you need to work through Brivo’s integrator channel for replacements — we cannot help with that specific credential type, and we will tell you so rather than sell you something that will not work.
Compatible Card and Fob Specifications
The cards and fobs American Key Cards supplies for Brivo installations are standard 125 kHz passive proximity credentials encoded in 26-bit Wiegand H10301 format.
| Specification | AKC Compatible Card | Brivo Unified Credential |
|---|---|---|
| Frequency | 125 kHz | 13.56 MHz |
| Chip | Standard 125 kHz prox IC | NXP MIFARE DESFire EV3, 8K |
| Bit format | 26-bit Wiegand H10301 | 56-bit (LEAF file structure) |
| OEM equivalent part | HID 1326, 1386, 1346 class | B-BUC3-56-SC50, B-BUC3-56-F50 |
| Programmed to facility code | Yes | Via Brivo platform only |
| Third-party supply available | Yes | No |
| Cloneable | Yes (standard 125 kHz prox) | No (AES-encrypted) |
| Security level | Low (no encryption) | High (AES, mutual auth) |
The standard 26-bit format delivers a facility code (1—255) and card number (1—65,535) to the Brivo panel over the Wiegand interface, which is identical to how any other access panel receives credential data. The Brivo ACS300, ACS400, and Brivo Smart Reader all accept this Wiegand input when configured for standard prox operation.
Compatible Readers on Brivo Installations
Standard 26-bit proximity cards from American Key Cards are compatible with the following Brivo reader hardware when configured for standard prox mode:
- Brivo ACS300 / ACS400 door readers (Wiegand 26-bit input)
- Brivo Smart Reader (BRS) with OSDP and Wiegand support
- HID readers integrated with Brivo ACS (ProxPro, ProxPoint, and MaxiProx configured for 26-bit)
- Allegion readers on Brivo panels supporting standard Wiegand input
If your property uses HID H10301-format readers feeding into a Brivo panel, the compatible card is the same standard 26-bit card used across most of the North American proximity market. See our full HID Prox H10301 format guide for more on how that format works and what information you need to order.
The Security Picture: What Can and Cannot Be Reproduced
This is where honest positioning matters. There are two very different security profiles in a Brivo deployment.
Standard 125 kHz proximity cards (the ones we supply) carry no encryption. The 26-bit data stream — your facility code and card number — is broadcast in the clear and can be read and reproduced using commercially available RFID tools. This is true of all standard 125 kHz proximity credentials, regardless of brand: HID, Farpointe, Schlage, or the compatible card from American Key Cards. The security these credentials provide comes from physical possession and access system configuration, not from cryptographic protection.
Brivo Unified Credentials are a different category entirely. The B-BUC3-56-SC50 and related Unified Credentials use an NXP MIFARE DESFire EV3 chip with AES encryption and the LEAF file structure. Mutual authentication is required on every read. There are no known successful cloning attacks against DESFire EV3 credentials. No third-party supplier — including American Key Cards — can issue, clone, or replicate Unified Credentials. If your building has made the full transition to Unified Credentials, you are working with a secured smart card ecosystem and must obtain replacements through Brivo’s integrator channel.
For comparison, other secured smart card formats in the same security tier include HID iCLASS SE, which similarly cannot be sourced from aftermarket suppliers. Understanding where your credential sits on that spectrum is essential before placing any order.
How to Identify Which Credential Type Your Brivo Property Uses
The quickest way to determine whether your Brivo installation uses standard prox or Unified Credentials is to examine an existing working card.
- Standard proximity cards are typically thin clamshell or ISO PVC cards with a visible card number and facility code printed on the surface or back label. They may show HID branding, a Schlage logo, or no brand at all.
- Brivo Unified Credential cards (
B-BUC3prefix) are contact-less smart cards, often with Brivo branding, and will have a 56-bit credential number in the Brivo dashboard under the credential record — not a standard 26-bit facility code and card number pair. - Your Brivo ACS dashboard, under the Credentials section, will also identify the credential type for enrolled cards. Standard prox entries will show a facility code and card number; Unified Credential entries will show the 56-bit token format.
If you are unsure after checking the card and the dashboard, contact us with a photo of the reader and the card label and we will help you identify what you have before you order anything.
Ordering Compatible Brivo Prox Cards
For properties confirmed to be running standard 26-bit proximity credentials on Brivo hardware, ordering from American Key Cards is straightforward.
What you need to provide:
- Your facility code (site code) — a number between 1 and 255
- The card number range you want programmed (e.g., cards 101 through 150)
- Quantity and form factor — clamshell card or key fob
Your facility code is most commonly found on the label of an existing working card, in the Brivo ACS credential record, or in the original system documentation from your installer. Our facility code guide walks through all the ways to locate it if you are starting from scratch.
We program each card to your exact specification before shipping. There are no OEM minimum order quantities — you can order the quantity you actually need, whether that is 5 cards or 500.
Why Non-OEM Cards Cost Less
Brivo’s branded proximity credentials are priced at OEM margin, which includes dealer markup, distribution overhead, and the platform lock-in that Brivo’s channel model depends on. Compatible cards from American Key Cards are programmed to the same 26-bit Wiegand H10301 specification, operate on the same reader hardware, and enroll in the Brivo ACS software identically. The credential that reaches the Wiegand reader input on your Brivo panel is indistinguishable in data terms.
The cost difference is not a quality difference. It is a distribution model difference. American Key Cards is a direct supplier, not affiliated with Brivo, supplying compatible credentials by specification.

Frequently asked questions
What card formats does Brivo ACS support?
Brivo supports its own proprietary 56-bit DESFire EV3 Unified Credential as well as standard 125 kHz proximity credentials including 26-bit HID H10301, Schlage, and AWID formats. HID iCLASS is also accepted on Brivo readers with the appropriate reader firmware. For most properties using standard prox, any compatible 26-bit card from American Key Cards will work.
Can I use standard HID proximity cards with a Brivo system?
Yes. Brivo panels and readers accept standard 26-bit Wiegand proximity cards in the same way any Wiegand-compatible panel does. Cards encoded in HID H10301 format, programmed to your facility code and card number range, enroll and operate in Brivo ACS exactly as the OEM-branded credentials do.
Are Brivo Unified Credentials cloneable or available from third parties?
No. Brivo's Unified Credential uses an NXP MIFARE DESFire EV3 chip with AES encryption and the proprietary LEAF file structure. These credentials are not cloneable, and no third-party supplier can produce functional Brivo Unified Credentials. Only Brivo and its authorized integrators can issue them. American Key Cards does not supply or clone Unified Credentials.
What information do I need to order compatible Brivo prox cards?
You need your facility code (also called site code) and the card number or range you want programmed. Both are typically on the card label of an existing working credential, in your Brivo dashboard under the credential record, or in the original system documentation from your installer. Contact us and we will guide you through what to look for.
