I'm a first-time poster here. I applied for SSDI in November 2001 and was approved in February 2002. I had my first CDR (the short front & back form) in November 2004 and my second one in November 2007. I was approved both times. I apologize in advance to all members who are struggling to get approved.

I received my latest approval letter today. Of course, it doesn't say how long my diary is; but I'm going to assume it is another 3 years.

I'm curious about some codes above my mailing address on the top left of the letter. Could anyone interpret them for me or guide me to a site where I can look them up?

The codes read:

00037337 01MB 0.360 T011,0113,CDR,PC3,BI

I also found it curious that this letter came from the Southeastern Program Center in Birmingham, AL. All my previous correspondence has come from Wilkes-Barre, PA.

Thank you!
