Transferring the Serial Number
When replacing a bottom case, retain the customer’s bottom case until the repair is complete.
Before installing the replacement bottom case, use a fine tip permanent marker to write the
original serial number clearly and legibly in uppercase box letters directly onto the inside of the
new bottom case.
CAUTION: Take great care in deciphering the small typeface of the etched serial number
on the bottom case. You might need a magnifying glass to see it clearly. It is imperative
that you transfer the correct alphanumeric characters. Keep in mind that Apple serial
numbers always use the numbers 1 and 0 instead of the Roman letters “I” and “O.”
