# Bin Profiles

## Blocking Bins

In this section, you can manage BIN (Bank Identification Number) restrictions to help control which credit cards are accepted in your system.

### Overview

Your CRM provides two primary ways to block or restrict BINs:

1. **Bin Profiles (Campaign-Level Control)**
2. **Blacklist (Account-Level Control)**

***

### 1. CRM > Gateways > Bin Profiles

Use **Bin Profiles** to create BIN ranges you want to restrict. You can then attach these profiles to specific campaigns. Any transactions using a BIN within the defined range will be prevented from processing **only** for the campaigns where the profile is applied.

**How to Create a Bin Profile:**

* Navigate to **CRM** > **Gateways** > **Bin Profiles**
* Create a new profile
* Define the BIN range(s) (e.g., `400000–499999`)
* Save the profile
* Attach the profile to the desired campaigns

**Example Use Case:**\
Preventing a certain card issuer from processing on a particular product line or promotion.

***

### 2. CRM > Admin > Blacklist

The **Blacklist** is used to block specific BINs **across your entire account**. Unlike Bin Profiles, the blacklist applies globally to all campaigns and gateways.

**How to Blacklist a BIN:**

* Go to **CRM** > **Admin** > **Blacklist**
* Choose **BIN** as the blacklist type
* Enter the BIN you want to block (e.g., `411111`)
* Save your changes

{% hint style="danger" %}
Once a BIN is blacklisted here, no transactions will process using that BIN, regardless of the campaign.
