EID Tags

HDX (Half Duplex) tags communicate with the reader in turns: the reader sends a signal, and the tag responds. HDX is commonly used in dairy operations and can perform well in certain environments with electrical interference.

FDX (Full Duplex) tags communicate with the reader simultaneously, allowing continuous signal exchange. FDX is well suited for many beef cattle, sheep, and deer operations.

Both technologies provide reliable animal identification.

EID (Electronic Identification) tags use radio-frequency technology to identify individual animals. Each tag contains a unique identification number that can be scanned using a compatible EID stick reader or panel reader. 

This allows producers to quickly identify livestock, reduce manual data entry errors, and link electronic identification (EID) numbers with visual identification (VID) numbers. 

The tag itself stores only the identification number. Additional information, such as weights, treatments, and animal records, is managed through compatible livestock management software.

Yes. A Premises Identification Number (PIN) or accepted Location Identifier (LID) is required to purchase official USDA 840 EID tags. 

This number identifies your ranch or farm location and helps support animal disease traceability. 

Standard 982 EID tags do not require a Premises ID, but they cannot be used as official USDA identification.

USDA-compliant EID tags (840) are approved for official animal identification in the United States. They support disease traceability and meet identification requirements for certain interstate livestock movements. A Premises ID or accepted Location Identifier is required to purchase them.

Standard EID tags (982) are intended for internal herd management and recordkeeping. They offer the same basic electronic identification functionality but are not accepted as official USDA identification. 

Both types can be used to collect and manage livestock data with compatible EID readers and software.

You can obtain a Premises Identification Number (PIN) by contacting your state's animal health department. Each state manages its own premises registration process.

A Premises ID identifies the physical location where your livestock are kept and is required when ordering official USDA 840 EID tags.
