  • What kind of ARN do you want to send to multiple of? An SNS topic has one and only one ARN. What are you trying to accomplish? – Matt Houser Jan 8 '16 at 16:11
  • i want to send notifications to multiple arn:aws:sns (SNS ARN)..what im trying to accomplish is prod team has difeerent SNS ARN and we application team has different one...so i need notifications to be sent to both the teams...and the topic is attached to a cloudwatch alarm – shiv455 Jan 8 '16 at 16:19
  • How about sending the notifcation to a single sns topic and registering two suscriptions (prod and app teams) for that topic? – Jukka Jan 12 '16 at 6:20

It is not possible to send a single message to multiple SNS topics at the same time.

A single SNS message can only be sent to one SNS topic.

However, you could setup a third SNS topic which is designed for messages that go to multiple topics.

For example, TopicC could be designed to forward to TopicA and TopicB. Doing this, you would subscribe a Lambda function to TopicC, and in that Lambda function, forward the message to TopicA and TopicB.

    If not a topic ARN, what kind of SNS ARN are you trying to send to? Please supply a sample ARN. – Matt Houser Jan 8 '16 at 16:38

Official documentation, "When a topic is created, Amazon SNS will assign a unique ARN (Amazon Resource Name) to the topic, ..." https://aws.amazon.com/sns/faqs/
