I received a letter in the mail saying it doesn’t appear to be sent by me, what is this?

Letters from bureaus you may receive

These letters are known as "stall letters." The bureaus use them to buy more time, as they are required by law to act within 30 days and assume this works to buy them more time. It does not, and we deal with these in response. Please forward the letter to us through the secure message portal in your dashboard, and we will handle it.
