Who is The Campaign Registry?

The Campaign Registry completes company identification checks and reviews SMS Campaign data to provide transparency to Mobile Network Operators (MNOs) in the United States. This process is required when businesses or organisations send high-volume SMS messages using 10DLC numbers. The verification process aims to reduce spam and fraud SMS messages for message receivers.

All your 10DLC Campaign questions, answered.

A 10 Digit Long Code (10DLC) number enables a business to send Application-to-Person (A2P) SMS messages in the United States. Using a 10DLC increases message reliability, security, and throughput due to The Campaign Registry validation process.
MNOs are Mobile Network Operators in the United States such as AT&T and T-Mobile. These mobile carriers provide cellular phone services to the general public and organisations.
10DLC Campaign use cases summarise the purpose of sending the SMS and indicates the type of content your SMS will contain.
Yes, it is industry mandated that message senders reply to START, STOP and HELP messages received from customers for 10DLC Campaigns.
Character limits and message parts apply when sending an SMS through Notifyre. It is important to be aware of message characters as this can affect your total message cost. The maximum character limit for a single SMS text message is 160 characters or 1 message part. However, Notifyre does not restrict its users from sending an SMS text message that is longer than 160 characters (unless Character Limit is toggled ON under SMS Settings). If a longer message (multi-part message) is sent, each message has a maximum of 153 characters due to seven characters being needed to facilitate re-joining of the message on delivery. For longer messages sent, the SMS is split into two or more messages that may be reassembled on delivery, so they are a single message (or, on some handsets, may be delivered as a series of separate SMS). If you send an SMS text message that contains more than 160 characters or 1 Message Parts, every 153 characters or part thereof will be charged as an additional SMS message. For example, if a SMS text message is sent with 300 characters, the SMS will contain 2 Message Parts and therefore the second Message Part will be charged as an additional SMS text message.
