# 30036: Validity Period Expired

Log Type: APPLICATION

Log Level: ERROR

## Description

The specified validity period on this message has elapsed.

### Possible causes

The message has spent more than the specified amount of time in Twilio's system. This can be due to a long time spent in the queue due to a combination of your [messaging rate limits](https://support.twilio.com/hc/en-us/articles/115002943027-Understanding-Twilio-Rate-Limits-and-Message-Queues), the number of messages submitted in rapid succession, and the amount of time you have allotted via the [ValidityPeriod setting](https://www.twilio.com/blog/validity-period-promotional-verification-use-cases) in your messaging service or on the message itself.

### Possible solutions

You can retry the message with a longer validity period and avoid sending very large batches of messages at a rate that far exceeds your messaging rate limits.
