Businesses using shared short codes often face issues like message filtering, compliance risks, and carrier restrictions. Transitioning to dedicated short codes or other messaging options ensures better control, security, and reliability. This guide explains the long code vs short code debate, why SMS short codes matter, and how businesses can make a smooth switch.

Why Move from Shared Short Codes?

A shared short code is used by multiple businesses. While cost-effective, it comes with risks:

1. Carrier Bans: Many mobile carriers no longer support shared short codes due to spam and misuse.

2. Message Filtering: If another business using the same short code violates policies, all messages from that code may be blocked.

3. Brand Identity Issues: Customers may receive messages from different businesses under the same short code, causing confusion.

Long Code vs Short Code: Which One to Choose?

Businesses switching from shared short codes have two main options: long codes or dedicated short codes

Long Codes (10-Digit Numbers)

Best for: Small businesses, personalized communication, and customer service.

Pros:

1. High-speed message sending (100+ messages per second).

2. Carrier-approved, reducing chances of message filtering.

3. Creates a strong brand identity.

Cons:

1. Higher cost compared to long codes.

2. Requires carrier approval, which may take weeks.

Steps to Transition from Shared Short Codes

To ensure a smooth move from a shared short code to a dedicated one or long code, follow these steps:

Assess Your Messaging Needs

1. Do you send high-volume marketing messages? → Use a dedicated short code.

2. Do you need a budget-friendly, two-way communication option? → Use a long code.

Apply for a Dedicated Short Code or Long Code

1. Contact an SMS provider to lease a dedicated short code.

2. If using a long code, register with A2P 10DLC (Application-to-Person 10-Digit Long Code) to improve deliverability.

Update Messaging Campaigns

1. Inform customers about the new number to avoid confusion.

2. Update marketing materials, websites, and customer service contacts.

Ensure Compliance with Carrier and Legal Rules

1. Follow CTIA (Cellular Telecommunications Industry Association) guidelines.

2. Get customer opt-in before sending marketing messages.

3. Provide an easy way for customers to opt out (e.g., texting “STOP”).

Test and Monitor Performance

1. Send test messages to ensure proper delivery.

2. Monitor response rates and fix issues quickly.

Switching from a shared short code to a dedicated short code or long code is essential for better control, security, and compliance. While SMS short codes are best for high-volume campaigns, long codes work well for two-way communication. Businesses should carefully choose the best option based on their needs and budget.
