Send 'em a photocopy of your Driver's License (with your current address on it) and your SSN card. If you wanna make absolutely certain, include a photocopy of a recent utility bill with your current address on it. DL and SSN can be blown up to probably 200% original size and still both fit on one page of an 8.5x11 sheet. Use page 1 of your utility bill on the back. Minimize the number of sheets you have to send and avoid paying extra postal charges. Be glad it's EQ and not TU. TU is the worst for correcting these sorta things. EQ, IMHO, is the easiest. I would not bother with CMRRR.
