# 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.

This is for new sales, rebills will still go through.
{% endhint %}

### 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.
{% endhint %}
