I too got a 'here is your BAEC PIN' email earlier this year, with no mention of an account number so I didn't pursue it as the Avios account seemed to continue working.
However this month's Lloyds Avios did not credit on the statement date, so (to avoid extortionate 7p/minute phone call charges) I had an online chat with an agent. We soon established that the missing Avios had indeed been credited to a different BAEC account, which they had set up for me without telling me the number... (like so many others further up this thread). However once all the security rigmarole hoops had been jumped through, the agent said he was able to merge the two accounts and, importantly, the new one into the old one. It will take up to five working days... we shall see.
