We have created a new Lockbox Filing Location Updates page on our website for customers to keep track of updates we make to lockbox filing locations. You can use this page to easily see which lockbox form filing locations we have updated and when we made the update. We will update this page regularly, but we always encourage you to check the “Where to File” section of your form’s webpage for the most current information on where to mail your form.
We periodically adjust filing locations among our lockbox facilities to balance our incoming workload for timely processing.
To receive updates on these lockbox filing location changes, please subscribe to the “Forms Updates” GovDelivery distribution list. In addition to updating the new page, we will issue a GovDelivery email with each filing location update and announce each update through social media.
