Configure chains
Chains are the third level of the front-end hierarchy. They represent a collection of associated merchants. Chains that do not exist in Express are created automatically when you enter the front-end hierarchy on a terminal setup. These automatically created chains have an initial description of "unknown" in the database. You can replace this description with a description of your choice at any time.
To configure a chain:
- On the global navigation bar, click the Main button.
The Express Homepage opens.

- In the Merchant Number field, enter a back-end merchant number.

In the Merchant Number field, enter a front-end merchant number (POS Merchant ID), and then in the BIN field, enter a BIN number.
- From the New Entity Type field, select Agent.
- Click the adjacent Add button.
The Hierarchy Information - New page opens.

- Enter or edit values in the fields provided as follows:
- BIN: A six-digit number that identifies the client bank. A BIN is assigned by TSYS Acquiring Solutions and is the highest level of the front-end hierarchy. The front-end hierarchy is used by TSYS Acquiring Solutions to route an authorization or batch to the correct Acquirer. BINS contain Agents, the second level of the front-end hierarchy.
- BIN Name: The name assigned to the BIN; usually the merchant's business or bank name.
- Agent: A six-digit number that the client bank uses to identify a smaller bank (or ISO) that processes credit card transactions through the client bank. Agents are the second level of the front-end hierarchy. They contain Chains and roll up into BINs. If a merchant does not process transactions using the Agent level of the front-end hierarchy, enter 000000 as a value for this field.
- Agent Name: The full name of the merchant's agent.
- Chain: A six-digit number that identifies a merchant's chain of locations or stores. The client or agent bank assigns a Chain. Chains are the third level of the front-end hierarchy. They contain Merchants and roll up into Agents. If the merchant does not process transactions using the Chain level of the front-end hierarchy, enter 000000 in this field.
- Chain Name: The name of a merchant's chain.
