If you live on Union Street in Carroll Gardens, you may have a holiday card coming to you. That is, if the dreaded Williamsburg Post Office ever figures out that the 11215 ≠ 11211. The envelope above, sent in by a Gothamist reader, was apparently mis-scanned by the post office and then delivered to the same wrong address four times. One theory by the 11211 recipient is that the bar code is causing the envelope to be sent to the wrong address again and again. But, as it turns out, the letter was delivered to the same address a fifth time even after the bar code was blacked out. Clearly, there was some sort of error in the complex USPS sorting process. Quick, cue Elvis!
