When an account expires, the customer has 90 days to update their payment information and pay the outstanding balance. After that, the account becomes inactive automatically, and it is necessary for you to hold onto the mail an additional 90 days, for a total of 180 days. 

iPostal1 follows the USPS regulation that states mail must be held for 6 months which is why our mailbox statuses are set to these specific timelines. After this time, it is up to you to decide if you’d like to negotiate forwarding for the customer. Forwarding mail after the account is closed is processed entirely outside of the iPostal1 system.

• Existing mail items should be maintained at your location for a 90 day period. This should not be confused with the 90 day grace period of an expired account.
   
• New mail items that is received for "Inactive" accounts should be returned to sender. According to the new USPS guidelines, mail must be marked as ‘Undeliverable, Commercial Mail Receiving Agency, No Authorization to Receive Mail for this Addressee'.
