SMS Long Code

An SMS long code is a standard 10-digit phone number used for sending and receiving text messages. Unlike short codes, which are typically 5-6 digits, long codes function like regular phone numbers and support two-way SMS,  and allow unicode characters. Unlike SMS short codes, which are typically 5-6 digits and designed for high-volume messaging, long codes function like regular phone numbers and support two-way SMS.

Key Features of SMS Long Codes:

• 10-digit format (e.g., 123-456-7890)

• Supports two-way messaging – Great for customer service and conversational texting.

• Lower message throughput – Typically 1 message per second (MPS), making it ideal for person-to-person interactions.

• Cost-effective – Cheaper than short codes but not suited for high-volume marketing.

• Can be local or toll-free – Businesses can choose numbers that match their area or offer toll-free messaging.

• Displays as a phone number – Unlike an alphanumeric sender ID, which can show your business or brand name.
