HID® Corporate 1000 (35-bit)
Not just a bigger prox format — a managed, registered format program. A facility guide to what Corporate 1000 controls and why credentials come only through HID's channel.
Can you buy third-party HID Corporate 1000 (35-bit) cards?
HID Corporate 1000 is a managed 35-bit proximity format program: HID registers a unique format number to your organization and controls its allocation, so credentials must be ordered against that registration through HID or an authorized integrator. Although it runs on the 125 kHz prox platform, the format itself is HID-controlled, which is why an independent supplier cannot produce Corporate 1000 credentials.

Corporate 1000 confuses people because the underlying technology is ordinary 125 kHz proximity, yet you can't just order the cards from anyone — and this page explains why. The value isn't the chip; it's the managed, registered format program HID wraps around it. Here's what that controls, how ordering works, and where an independent supplier fits (the standard-format prox in the same building, not the Corp 1000 credentials).
Why Corporate 1000 is different from a normal prox format
Standard proximity formats like 26-bit H10301 are open — the structure is public, and anyone can program a compatible card. Corporate 1000 deliberately isn't. It's a managed format program in which HID registers a unique 35-bit format number to a single organization and controls its allocation, so no two customers share a format and no one outside the program can legitimately produce cards in it.
The 35-bit structure also solves a practical scaling problem: it provides a large, cleanly managed number space so a big organization can issue credentials for years without the facility-code collisions that plague the small 26-bit space. But the headline feature is the control, not the bit count — Corporate 1000 is about a format that belongs to you and is administered on your behalf.
What the managed program actually controls
Under Corporate 1000, HID holds the registration of your format number and manages issuance against it. That means card orders are checked against your registration, numbers are administered so they don't collide, and the format can't be duplicated by a supplier who simply knows the bit layout — because knowing the layout isn't enough without the registered allocation.
For a facility, this is the security and administrative benefit rolled together: your credentials sit in a namespace that's yours, HID prevents accidental or unauthorized duplication of your format, and your numbering stays orderly across a large, long-lived deployment.
How Corporate 1000 credentials are ordered
Because the format is registered and managed, credentials are ordered through HID or your authorized integrator against your organization's Corporate 1000 registration. There's no aftermarket path — an independent supplier can't produce cards in your registered format, and that's the point of paying for the program.
For replacements and growth, your integrator places the order against your registration on standard HID card bodies (the same physical clamshell, ISO, and fob styles used across HID prox). You manage enrollment and revocation in your access software as usual; the format registration is what stays controlled.
Where an independent supplier fits
We don't supply Corporate 1000 — the registered format is HID-controlled, and we won't claim to reproduce it. What we can supply is any standard, open-format proximity credential the same building runs: 26-bit or 37-bit prox on secondary doors, gates, or outbuildings that were never brought into the Corp 1000 program.
If you're auditing a large site and trying to separate the Corporate 1000 population from the standard-format prox, send photos of the credentials and readers. We'll help you identify which is which, supply the open-format stock, and point you to HID's channel for anything in your registered Corporate 1000 format.

How to order HID Corporate 1000 (35-bit) credentials
Corporate 1000 is a controlled format: HID registers and manages your organization's unique 35-bit format number, and credentials must be ordered against that registration through HID or your authorized integrator. American Key Cards does not supply Corporate 1000 credentials, because the format allocation is HID-controlled and cannot be reproduced by a third party.

We do not sell HID's secured credentials; brand and product names appear only to identify the technology discussed, and all trademarks remain the property of their respective owners.

How it worksHID Corporate 1000 (35-bit) — FAQ
Can I buy Corporate 1000 cards from an independent supplier?
No. Corporate 1000 is a managed format program — HID registers and controls your organization's unique 35-bit format number, and credentials must be ordered against that registration through HID or your integrator. Knowing the bit layout isn't enough to produce a valid card, which is the entire point of the program.
It's just 125 kHz prox — why can't you supply it?
Because the value and control are in the format registration, not the chip. HID administers your unique format allocation to prevent duplication and manage your numbering; an independent supplier can't legitimately issue against your registration. We can supply the standard open-format prox in the same building.
How do we order more Corporate 1000 credentials?
Through HID or your authorized integrator, against your organization's Corporate 1000 registration. They're produced on standard HID card bodies and enrolled in your access software as usual; the registered format is what stays controlled.
What's the difference between the 35-bit and 48-bit Corporate 1000?
Both are managed Corporate 1000 formats; the 48-bit version offers an even larger number space for the biggest deployments. Both are registered and HID-controlled, so both are ordered through HID's channel rather than an aftermarket supplier.
