If your mail piece doesn’t have a tracking event, first check to see how much time has elapsed between your mail piece Send Date and the current date. Typically, it’ll take 3 business days (for First Class Mail), or 4-5 business days (for Standard Class Mail) from the time of your Send Date for USPS tracking events to appear.
If more than 5 business days have elapsed since your Send Date and you don’t have any tracking events, send an email to email@example.com. Our team will be able to confirm whether the mail piece has been mailed.
*Please note that if it has been more than 30 days, Lob will not have access to the API logs which track mailpiece tracking events, but you should be able to see the date when the mail piece was scanned by clicking on 'View details'
